- A series of versions exists: v1.0, v2.0, v2.1, v3.0. NRT version also exists. Version 3.0 is close to Snow CCI, Combination of climate station snow depth observations and forward microwave emission model simulations with SMMR and SSM/I satellite passive microwave data. Version 3.0 includes several enhancements: (1) inclusion of lake ice; (2) revised modelling of forest canopy Tb; (3) enhanced surface observations and quality control. A V3 bias-corrected version includes corrections based on snow. Data is available at daily time step after 1987, every other day before that with some gaps. Also available weekly and monthly.
