The LPDR v2 record provides consistent land parameter retrievals spanning both AMSR-E and AMSR2 (AMSR-E/2) operational records, and are suitable for science quality evaluations of key land parameters important to ecosystem processes. A detailed LPDR (v2) accuracy and performance assessment was conducted over the global domain (Du et al. 2017). Additional bit-wise data quality files (QA) are provided in GeoTIFF (.tif) format for describing the quality information of LPDR data files. The Questions and feedback should be sent to Jinyang Du (jinyang.du@ntsg.umt.edu).EnglishNASA NSIDC DAACNASA NSIDC DAACNASA National Snow and Ice Data Center Distributed Active Archive Centerhttp://nsidc.org/daac/index.htmlData Center ContactNSIDCUser Servicesnsidc@nsidc.org1-303-492-61991-303-492-2468National Snow and Ice Data CenterCIRES, 449 UCBUniversity of ColoradoBoulderCO80309-0449USAHTTP173 GBGeoTIFFKim, Y., Kimball, J.

Satellite microwave remote sensing of daily land surface air temperature minima and maxima from AMSR-E. IEEE J. Sel. Top. Appl. Earth Obs. Remote Sens. 2010, 3, 111–123.Notice to Data Users: The documentation for this data set was provided solely by the Principal Investigator(s) and was not further developed, thoroughly reviewed, or edited by NSIDC. Thus, support for this data set may be limited.
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 Advanced Microwave Scanning Radiometer 2(AMSR2) instrument on the Japan Aerospace Exploration Agency (JAXA) Global Change Observation Mission 1st- Water (GCOM-W) satellite. The daily parameter retrievals extend from 19 June 2002 to 30 June 2017 and include daily air temperature minima and maxima (Tmn and Tmx) at approximately 2 m in height; 60-day temporally smoothed fractional open water cover (fw) and daily (non-smoothed) fractional open water (fwns) estimates; vegetation optical depth (VOD); surface soil moisture (vsm) at ~1 cm soil depth; and integrated water vapor content of the intervening atmosphere (V) for the total column. The global retrievals were derived over land for non-precipitating, non-snow, and non-ice covered conditions. The primary input data were daily AMSR-E and AMSR2 dual polarized multi-frequency, ascending and descending overpass brightness temperature data. The total volume for this data set is approximately 173 gigabytes.
