SMOS-IC v2

The SMOS-IC v2 product includes both a soil moisture (SM) and a L-band vegetation optical depth (L-VOD) data set which are currently at the basis of several studies evaluating the impact of climate and anthropogenic activities on aboveground carbon stocks. Since the release of the first version, the algorithm has been significantly changed in support to key applications. It has a spatial resolution is around 0.25° and a daily temporal resolution.
