摘要：
Launched in 2009, the SMOS satellite provides measurement of Soil Moisture (SM) and Vegetation Optical Depth (VOD) at L-band over land at high temporal resolution. L-VOD is known for being a good proxy for biomass, and 10 years of measurements are now available to analyze the behaviour of biomass over the whole world. Here, we investigate the links between L-VOD and SM seasonality, together with other vegetation and climatic variables (LAI, precipitation, temperature, and insolation). We also present time series of climatic variables for specific areas, showing remarkable trends of the L-VOD over the 10 year period (2010-2019), linked to climate change.
