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.
