-TSMM Terrestrial Snow Mass Mission
-GNSS-RO community for Soil Moisture/Water bodies
On LSM shortcoming:
-Diurnal cycles
...
-Snow Fraction (need to represent hysteresis)
-Variable Water cover (separating permanent water from seasonal/inundated areas, ML approaches to delineate water bodies)
-Moving towards 2-way coupling to reinfiltrate and re-evaporate surface water and consider in LDAS (SAR data, SWOT data in October 23, P-band SNOOPI (RFI), BIOMASS, Copernicus Water-bodies/Water-product, Organic soil, Wetland)
-Ancillary datasets compilation
-Hydrology
On insito observations:
COSMOS network very promising for verification. Is there an effort
Metrics for using insitu soil moisture and snow observations
