Executive summary
The EO-based crop productivity indicators provide insight in the productivity and yield of the four main crops (wheat, maize, soybean, rice) and main production regions at a global scale over the period 2000-2018. The algorithm combines earth observation data of plant light interception with a simple crop model that converts intercepted light into crop biomass and uses a phenological model to determine the cropping season length.
The product is provided at a 0.1x0.1 degree resolution and can be used to analyse the effect of climate variability on crop yields at regional scale. The product is not suitable for field scale analysis and is therefore only provide at the 0.1 degree aggregated level. The data product contains three main variables:
