Earth Day - Thinking about our Globe
Each year, on the 22nd of April we celebrate Earth Day to raise awareness on humankind's impact on the Earth's resources, such as climate change, deforestation, habitat loss, and trafficking and poaching.
In days of a heated climate change debate and to provide planning and decision making support, objective, consistent, and quality-assured data and information about the various biospheres' state is of vital importance.
The European Centre for Medium-Range Weather Forecasts (ECMWF) implemented the Copernicus Climate Change Service (C3S) to generate Climate Data Records (CDRs) of Essential Climate Variables (ECVs) using multiple satellite, in-situ, and re-analyses of climate models and their projections. The C3S Land Biosphere component uses 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 below. 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.
The image below shows the impact of the the 2018 summer drought in which vegetation gradually dried out, resulting in lower LAI (indicated by the red areas) than the 1998 – 2017 average.
