MEaSUREs has added SSM/I data from the F11 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 now 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.
NOAA@NSIDC is pleased to announce the release of the Sea Ice Index in GeoTIFF format. GeoTIFF files are available for both concentration and extent data for both hemispheres at daily and monthly resolutions. The daily and monthly GeoTIFF files provide the Sea Ice Index concentration and extent data in a georeferenced format. The GeoTIFF images are single band images with an embedded color table to make visualizations of the dataset in GIS programs as easy as possible.
The International Glaciological Society will hold an International Symposium on ‘Polar Ice, Polar Climate, Polar Change’ at the University of Colorado in Boulder on 14–19 August 2017. The meeting will take place at the University Memorial Center’s Glenn Miller Ballroom.

Are you looking to customize MODIS, ICESat/GLAS, AMSR-E, or SMAP data? While customization options such as subsetting and reformatting are currently available through the NASA Earthdata Search web application, these services can now be accessed programmatically as a synchronous REST interface. How does the API work? Programmatic access to these data services is provided via an HTTPS URL.
