Funded by the European Space Agency from June 2022 to June 2024
The OSMOSE project, conducted in the frame of the 10 years of the SMOS satellite, aims at estimating temporal and global maps of forest abevoground biomass, by creating two consistent data cubes containing long, consistent, times series of vegetation variables estimated with microwaves and visible observations. The microwave Vegetation Optical Depth (VOD) is derived at frequencies from 1.4GHz to 37 GHz, whereas vegetation variables such as the Fraction of Absorbed Photosynthetically Active Radiation or Leaf Chlorophyll Content are derived from visible wavelengths.
The methods for estimating forest biomass will be evaluated by assessing the most efficient and appropriate method to estimate AGB, and improving current biomass estimates from remote sensing observations.
SMOS is at the core of this project as it provides 12 years of L-band observations, which are sensitive to forest biomass and vegetation water content.
