This data set contains satellite-retrieved geophysical parameter files generated from the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the National Aeronautics and Space Administration (NASA) Aqua satellite and the Advanced Microwave Scanning Radiometer 2 (AMSR2) sensor on the JAXA GCOM-W1 satellite. The geophysical parameters include daily air surface temperature, fractional open water cover estimates, vegetation optical depth, surface volumetric soil moisture, and atmosphere total column precipitable water vapor. The global retrievals were derived over land for non-precipitating, non-snow, and non-ice covered conditions.
Data Set ID:
NSIDC-0451
Daily Global Land Parameters Derived from AMSR-E and AMSR2, Version 2
This is the most recent version of these data.
Version Summary:
For Version 2, data were processed for the entire AMSR-E operational record (19 June 2002 to 4 October 2011) and part of the AMSR2 record (24 July 2012 to 30 June 2017), with planned updates and LPDR continuity enabled from continuing AMSR2 operations. The associated version 2 algorithms were revised from the prior version 1 algorithm (Jones et al, 2010) and as detailed in the literature by Du et al., 2014, 2015 and 2016) and summarized in (Du et al., 2017).
