MEaSUREs has added SSM/I data from the F14 platform to the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR data set available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The temporal coverage is 9 July 1987 through 4 October 2011. This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.

The MEaSUREs Annual Antarctic Ice Velocity Maps, 2005-2016 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides 11 annual maps of Antarctic ice velocity from 2005-2016. The maps are assembled using ALOS PALSAR, ENVISAT ASAR, RADARSAT-1, RADARSAT-2, Sentinel-1, TerraSAR-X (TSX), TanDEM –X (TDX) SAR data, and Landsat-8 optical imagery acquired between 2005 and 2016.

Terra MODIS experienced a data outage stemming from the Science Formatter Equipment (SFE) Assembly. All data between time stamps 2017/114 0320 and 2017/114 1950 are unavailable and likely unrecoverable. Level 3 daily products remain unavailable since the beginning of the outage because of post outage data recovery and QA/QC procedures. However, Level 2 products have been recovered and are available outside of the aforementioned time stamps. If you have any questions, please contact NSIDC User Services at nsidc@nsidc.org.
