Derived Vegetation Water Content used by the NASA-ISRO Synthetic Aperture Radar (NISAR) Mission
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/nivwc-1
The Derived Vegetation Water Content used by the NASA-ISRO Synthetic Aperture Radar (NISAR) Mission collection contains vegetation water content products used for creation of products from the NISAR mission.
Description
Vegetation water content (VWC) ancillary serves two purposes in the soil moisture algorithms: (1) to correct for the effect by vegetation during retrieval by the physical model inversion approach (2) to flag heavily-vegetated regions where the retrievals are deemed not so reliable such as forest.
The products provided are interpolated to 200 meters using the the daily climatology of 1-km resolution VWC generated by the SMAP project derived from MODIS data.
