General description

Biomass Proxy is a fusion of microwave and optical satellite imagery, using the advantages of each to accurately estimate relative above-ground crop biomass regardless of cloud cover and at a high spatial resolution (10 m x 10 m).

It integrates microwave data from the European Space Agency (ESA) Sentinel-1 satellites and optical images from its Sentinel-2 satellites.

Planetary Variables then fuses the output from these combined data sources in an algorithm designed to provide a reliable measurement of crop biomass over agricultural areas under all circumstances.

This is a relative measure of biomass, so each pixel value has a value of 0 (low biomass) to 1 (high biomass).

It should be computed over agricultural fields.
