TSM and Turbidity  Turbidity is a measure of the clarity of water and an important parameter in environmental monitoring. High turbidity can be linked to a high amount of sediments suspended in water. These sediments prevent light reaching aquatic plants and organisms and can carry contaminants. The aquaculture sector, environmental agencies or dredging companies can all benefit and take actions based on turbidity measures. Although PROBA-V is a vegetation satellite designed to observe the land surface, the satellite covers coastal waters as well.  The resolution and specifications of PROBA-V facilitate the generation of almost daily turbidity maps in coastal areas. This animation shows the combination of a PROBA-V image and a turbidity map of the Eastern part of the North Sea, near Belgium and the southern part of the Netherlands. The image was captured on 3rd of April 2016. You can see higher turbidity values in the Scheldt river and near the coastline around Zeebrugge.

The resource over-consumption was recorded first in the early 1970s. During the following decades, Overshoot Days gradually occurred earlier, from late December in the 1970s to 29 July this year. Additional to Earth Overshoot Day, a country’s Overshoot Day is the fictive Earth Overshoot Day if the entire world population would consume similar to a country’s population. These span a range from 11 February (Qatar) to 18 December (Indonesia). The image below shows a 10-day 300 m composite (11 – 20 August 2017) of Brazil, which has its Country Overshoot Day closest (31 July) to Earth Overshoot Day. The image shows among others the Amazon river basin and its vast tropical rain forest in dark green, with intermittent light brown patches indicating deforested areas. The extensive brown/reddish area in central and eastern Brazil indicates the Cerrado (tropical savanna) plateaus.

This day was established in 1972 by the United Nations to raise people’s awareness on our vulnerable environment and the actual environmental issues. This year’s World Environment Day is hosted by China, with a theme on air pollution, a world-wide issue that is most prominent in the Asia-Pacific region. In this region, air pollution directly or indirectly causes an estimated 4 million deaths (from the 7 million people world-wide). In some major Chinese cities, the air can sometimes be so polluted that even on a ‘clear’ sunny day people hardly see the sun.  Nevertheless, the Chinese government is taking measures to improve the air quality, which is already observed over the last few years from space by dedicated air quality satellite sensors. Below we show a PROBA-V image of 17 May 2019 of Zhanjiang, a city in the south of China with ~6.5 million inhabitants, located at the South Chinese Sea. The city can be seen as a grey area in the top-middle part of the image. At the bottom of the image the northern part of the Hainan island is visible.

Copernicus Climate Change Service  In days of a heated climate change debate, objective, consistent, and quality-assured data and information about the various biospheres’ state is of vital importance. Such data will encourage our policy makers to take proper actions and stop global warming. Therefore the European Centre for Medium-Range Weather Forecasts (ECMWF) implemented the Copernicus Climate Change Service (C3S), one of the six thematic information services provided by the Copernicus Earth Observation Programme of the EU. In C3S, Climate Data Records (CDRs) of Essential Climate Variables (ECVs) using multiple satellite and in-situ data, as well as re-analyses of climate models and their projections, are generated. The C3S Land Biosphere component uses e.g. PROBA-V data to generate the longest possible, consistent, and mature satellite-based biosphere ECVs. An example of such a long-term consistent biosphere satellite data record is shown in the animation above. It presents for 2018 the monthly Leaf Area Index (LAI) anomaly (deviation) over Europe from the 1998 – 2017 average using harmonized SPOT-VGT and PROBA-V observations. It can be seen very well that due to the 2018 summer drought the vegetation’s leaves gradually dried out, resulting in lower LAI (indicated by the red areas) than the 1998 – 2017 average.

Red Sea  World Wildlife Day, on March 3rd, reminds us of the signing of the Convention on  International Trade in Endangered Species (CITES). It has become the most important global, annual event dedicated to the conservation of wildlife. This year, the event focuses on UN SDG 14 – the sustainable use of our planet’s oceans, seas and marine resources. The Red Sea is a rich and diverse ecosystem, supporting over 1200 species of fish, in part due to the 2000 kilometers of coral reefs along its coast. It features on the WWF’s Global 200 list of priority ecoregions for conservation. This 100 m image of the northern half of the Red Sea, highlights nicely the coral reefs along the coast of the Saudi region Tabuk (east). The wildlife and reefs make for attractive diving spots for tourists, like those visiting Ras Mohammad, the marine national park nearby Sharm El Sheikh, at the tip of the Sinai peninsula (north).

It drains 5 – 10% of West-Antarctica’s ice sheets and is the continent’s fastest melting glacier. Since the 1990s, the glacier has thinned by about 1.5 meters per year and its flow into the sea has increased. Recently, as for the previous years, a large iceberg with an area of ~300 km2 calved off the glacier. As PROBA-V observes Antarctica during the austral summer, it was able to capture this calving. The 300 m image of 19 November 2018 shows the iceberg a couple of weeks after it calved off from the Pine Island Glacier. PROBA-V will observe Antarctica till the end of February 2019. All observations (November 2018 - February 2019) are made available through the data portal and the Mission Exploitation Platform (MEP) so users can play around with the data using all available tools.

The park’s area is geologically active and contains about half of the world’s geysers and hydrothermal features. The Yellowstone Lake is located at 2,350 m altitude over a supercaldera (~70 km diameter) that could emit about 2,500 km3 of ash when erupting.  Yellowstone’s climate is significantly influenced by the Snake River Plain, a geological feature that formed over millions of years when the North-American tectonic plate moved over the Yellowstone hotspot. This eventually resulted in a 100 km wide channel from the Pacific Ocean into Yellowstone Park, enabling a dominant maritime airflow into the park and adjacent areas. This leads to annual precipitation amounts of up to 2,000 mm in the park’s western part, with abundant snow during November – April, as is visible from the images covering the four seasons from autumn (upper left) through summer (lower right).

On this day, a large number of events promote awareness and call to action to ensure food security worldwide, with a strong message: hunger can be ended in this lifetime. Let’s work together to become the Zero Hunger Generation! Within FAO’s Global Information and Early Warning System (GIEWS), a specific system for global drought monitoring was addd: the Agricultural Stress Index System (ASIS). For ASIS, VITO automatically processes Remote Sensing data to produce maps on the extent, duration and severity of drought events every 10 days, like the example for Nicaragua above. Information on the historical probability of drought is provided as well.  Such information is found particularly useful to guide public investments, for instance in the establishment of irrigation systems.

The 40 to 80 million adult locusts in each square kilometre of the swarm can eat up the same amount of food in one day as roughly 35 000 people. Combined with its ability to migrate over large distances, this makes the Desert Locust a threat to food security in many countries in and around the Sahara and the deserts of the Middle East and South-West Asia. To help monitor and control the locusts, the United Nations Food and Agriculture Organization (FAO) operates a central information service, called Locust Watch, and gives out timely warnings, forecasts, training and support to the staff of locust control centres in the affected countries. In a pilot on the MEP platform and supporting FAO’s efforts, UCL extended an algorithm used to produce dynamic greenness maps to use PROBA-V 100 m input data instead of MODIS. These maps highlight areas in need of locust surveying.

It included the first VEGETATION instrument (VGT-1) with four optical bands to monitor global vegetation at 1km spatial resolution. The ground segment preparations started one year earlier and provided the starting point for VITO’s operational processing and delivery of Earth Observation satellite data, as part of a joint programme of the European Commission, France, Belgium, Sweden and Italy. This week’s image celebrates this anniversary, by taking us back to the very first global, 10-daily synthesis (S10) of 1-10 April 1998. With SPOT5-VGT2 (since 2003) and PROBA-V (since May 2013), the time series of vegetation data is continuing. It has been an interesting journey indeed: from a small team, with just a few computers and less than 1TB of data, up to today’s data centre with 5PB storage, on-demand and cloud processing, used for multi-mission data processing. These capabilities were used in over 15 years of R&D projects, and are still used in operational services, like those for the European flagship programme Copernicus, still called GMES when it was established back in…1998.

In Dec 2017, the BELHARMONY research project started off with the aim to assess the consistency between recent, high resolution Earth Observation sensors, focusing on PROBA-V (100m), Sentinel-2 and Landsat-8 and DEIMOS-1. It addresses for instance biases between the sensors at early processing stages (level-1, top-of-atmosphere) using a series of calibration sites. An example is the dry lakebed of the Railroad Valley Playa calibration site in Nevada, USA, shown in this week’s 100m PROBA-V image. In addition, BELHARMONY looks into the differences in the relative spectral response (for level-2 reflectance products) and the use of a common processing chain towards a set of derived land and water parameters (level-3 processing). To evaluate the impact of the harmonization measures, the project relies on EO and in situ data collection over the network of urban, agricultural and coastal sites from the Belgian BELAIR network.

Atacama, Chile and Catamarca, Argentina  In the Southern Volcanic Zone of the Andes, on the border of Chile and Argentina, at altitudes ranging between 3 and 6.5 kilometers above sea level, PROBA-V spotted a lovely patchwork of volcanic fields, with several calderas and lava flows (black), alternating with salt deserts and salt lagunes (white) in this false-colour, 100 m image from April last year. Prominently visible is the elongated and narrow salt desert of Antofalla, the longest in the world. It is accompanied by the Namesake volcano (6,400 m) to its northwest. In the northwest corner is the Lago Salar del Hombre Muerto (salt lake of the dead man), a name that testifies to the harsh, dry and cold environment of this remote area, used mainly for tourism and scientific expeditions. Despite the aridity (less than 200 mm precipitation annually), there are some green pastures and small lakes (Lagunas), shown here in bright blue that support for instance Andean wildlife such as flamingos, foxes or vicuñas.

The EO data they use is derived from SPOT/VGT and PROBA-V, in the context of a long-standing bilateral partnership ACF-VITO and the Copernicus Global Land Service. It’s a clear example of a collaboration that can make a real difference on the ground, by feeding into a web-GIS portal that shows the latest maps on water resource availability and biomass production anomalies (like the examples above). These maps and data are also shared with other humanitarian aid workers and used as input for Mali’s national early warning system.

This station, covering an impressive 23 square kilometres, has become one of the most productive in the world, yielding around 850MW in solar and almost 1300MW in hydroelectric power. Moreover, the joint regulation of the solar park and the dam’s turbines balance the output from the variable solar power generation and helps to conserve water. The picture also captured Qinghai Lake, the largest lake in China, located in a hollow of the Tibetan Plateau at at 3200 m above sea level. No deeper than 30 meters and declining in depth, it’s still a major water source for many. The lake shrunk in surface area in most of the 20th century, but its size is recovering since 2004.

Chott Melghir, Algeria  The 100 m false-colour PROBA-V image of 12 September 2017 shows us a mix of wadi, agriculture patterns, alluvial fans,  around Chott Melghir (upper center) and Chott Felrhir (lower center), 2 endorheic salt lakes in northeastern Algeria. It lies almost entirely below the sea level and contains the lowest point in Algeria, −40 meters. The shallow waters of the lake contain scarce vegetation composed of 72 species of plants which have adapted to salty water, such as Parish's glasswort, sea lavender, rushes, glasswort, etc. Some species are unique for Algeria and 14 are endemic.

It shows the huge, almost perfect circle that scientists believe resulted from the impact of a giant meteorite, 200 million years ago. The collision melted the rock and pressure created the central mound. The crater is a multiple-ring structure about 100 km across, with the reservoir at its 70 km diameter inner ring being its most prominent feature. It surrounds an inner island plateau called René-Levasseur Island. The lake and island are clearly seen from space and are sometimes called the "eye of Quebec."

The large island in the west is called Ayon. Pevek is a port town located just southeast of the two small islands east of Ayon. Apparently Pevek is the northern-most town in Asia.  The two islands are Bolshoy Routan Island (larger) and Malyy Routan Island (smaller one). Ayon is inhabited by the Chukchi people. The Chukchi are indigenous to the area and many still practice a semi-nomadic lifestyle, hunting marine wildlife and herding reindeer.  The island, peninsula and delta is peppered by lakes and is clearly a wetland habitat with many rivers draining into the bay especially the Chaun river. Chaunskaya Guba is a natural reserve or zakaznik in Russian. Eight species of whale have been reported here with only 3 common species: Beluga, Gray and Bowhead whale. Walrus and four species of seal are reported from here while the Polar Bear is common. Several Eider species migrate from the east into the Bay during the Spring. The bay itself is dominated by Bivalves.  Ayon is also a seabird colony with nearly 10,000 individuals. The wetlands are rich in plant communities typically known as salt marsh vegetation. It consists of sedges, grasses, herbs of the families: Cyperaceae, Pooaceae and Rosaceae typically native to the Arctic. Notice the distinct spectral light brown of North Ayon island indicative of a Poacea dominant habitat. The hills inland of Pevek are part of the Chukotsky range and are composed of granite dated to 100 million years ago. These are dark brown in colour sitting above the green mat of vegetation. These hills can be seen around Pevek as well.  Chintan Sheth from India is the winner of our 4th PROBA-V Quiz! Congratulations!

This town is on a significant route for cattle trade in the Haud, an area with typical thorn-bush and grasslands used by traditional Somali herdsmen. Along with the more populated, nearby districts (woredas) in the Somali region, and neighbouring parts parts of Kenya (to the southwest) and Somalia (to the east), this area in the Horn of Africa is regularly hit by drought, often driven by El Niño climatic events. With cumulative rains between June 2016 and June 2017 reaching the first or second lowest level in 36 years, the prolonged drought drove a major food security emergency and marked the areas as priority for international food aid, disaster relief efforts and health workers.

Standing Rock Indian Reservation, USA  At 9 August, the UN “International Day of the World’s Indigenous Peoples” is celebrated to pay attention to the survival, dignity, and well-being of indigenous peoples. This year’s theme is dedicated to the 10th anniversary of this day. The American Indians are probably the most well-known Indigenous Peoples. Dispossessed from their land and relocated to dedicated areas remote from European-populated areas during the 19th century, the United States Government created dedicated reservations for the American Indians from the 1880s onwards.  The Standing Rock Indian Reservation is one of seven reservations (established in 1889) created for Sioux Indians, covering an area of nearly 9,300 km2 in North and South Dakota. Last year, large protests against the construction of the Dakota Access Pipeline through the Reservation area drew international attention. The false-colour 100 m image of 3 June 2017 shows the Standing Rock Indian Reservation area, with a remarkable alternation of red and grey appearing patches, which indicate cultivated and bare soils, respectively. At the right part of the image, the Missouri River is visible, flowing southward towards Saint Louis to merge with the Mississippi River.

Mangroves provide substantial benefits, by improving food security, protecting against storms or shoreline erosion, providing habitats of rare wildlife species and sequestering and storing blue carbon important for mitigating climate change. To this occasion, PROBA-V visits the Can Gio mangrove forest and biosphere reserve in Vietnam, ~40 km southeast of Ho Chi Min city that is visible in grey tones at the top of the image. The myriad of waterways through the mangrove forest (dark red, centre) and agricultural fields (dark tones on the banks) are particularly striking. This is put in contrast to the city’s growth in population, which has nearly doubled to 8.5 million over the last 20 years.

The Belgian Science Policy Office (BELSPO) and VITO are proud to be the local organizer of Multitemp 2017, to take place in Bruges, Belgium this week (27-29 June). By focussing on methodological improvements, Multitemp welcomes and encourages the cross-fertilization between application domains like climate, biodiversity and ecosystems, forestry, water and coastal management. Those application domains are particularly relevant in the protection of the extensive wilderness of the Florida Everglades, displayed in this PROBA-V image from early May 2017. The southern 20% of the original Everglades are a national park and one of only three locations in the world that are recognized, simultaneously, as International Biosphere Reserve, World Heritage Site (UNESCO) and Wetland of International Importance (RAMSAR).

The gulf is named after the port city of Mottama (formerly known as Martaban). The Salween Sittaung and Yangon rivers flow into it.  A characteristic feature of the Gulf of Martaban is that it has a tide-dominated coastline. Tides range between 4–7 m, with the highest tidal range at Elephant Point in the western Gulf of Martaban. During spring tide, when the tidal range is around 6.6 m, the turbid zone covers an area of more than 45,000 km², making it one of the largest perennially turbid zones of the world's oceans. During neap tide (the lowest level of high tide), with a tidal range of 2.98 m, the highly turbid zone coverage drops to 15,000 km². The edge of the highly turbid zone migrates back-and-forth in-sync with every tidal cycle by nearly 150 km. This 300 m image of 4 March 2014 shows the Gulf of Martaban and the various rivers flowing into it. The light-brown haze in the Gulf indicates increased phytoplankton concentrations.
