Smerge-Noah-CCI root zone soil moisture 0-40 cm L4 daily 0.125 x 0.125 degree V2.0 (SMERGE_RZSM0_40CM) at GES DISC
Smerge-Noah-CCI root zone soil moisture 0-40 cm L4 daily 0.125 x 0.125 degree V2.0 is a multi-decadal root-zone soil moisture product. Smerge is developed by merging the North American Land Data Assimilation System (NLDAS) land surface model output with surface satellite retrievals from the European Space Agency Climate Change Initiative. The data have a 0.125 degree resolution at a daily time-step, covering the entire continental United States and spanning nearly four decades (1979 to 2016). This data product contains root-zone soil moisture of 0 - 40 cm layer, CCI derived soil moisture anomalies of 0-40 cm layer, and a soil moisture data estimation flag.

Version Description
SMERGE version 2.0 is an improvement of the previous version (v1.0) of the dataset. The main differences between SMERGE v1.0 and SMERGE v2.0 are the addition of a new variable, CCI derived soil moisture anomalies of 0-40 cm layer, and an additional year of data for 2016. -
