The Daily Global Land Parameters Derived from AMSR-E and AMSR2, Version 3 dataset, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated. The dataset now covers the time period from 19 June 2002 to 31 December 2021. The 2016 data record has also been reprocessed to correct an issue caused by an incomplete reading of the 2016 brightness temperature record, which affected the DOY 204 to 366 data files.
This dataset is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program. It contains satellite-retrieved geophysical parameters generated from the AMSR-E instrument on the NASA Aqua satellite and the 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 atmospheric total column precipitable water vapor. The global retrievals were derived over land for non-precipitating, non-snow, and non-ice covered conditions.
