Update to MEaSUREs Greenland Ice Velocity Maps from InSAR

NSIDC_USO

The MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, Version 2  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, consists of mean monthly velocity maps for selected glacier outlet areas. The maps are generated by tracking visible features between optical image pairs acquired by the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), the Landsat 8 Operational Land Imager (OLI), and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). The Version 2 update expands the temporal coverage of the data set through September 2016, using cross-path Landsat pairs to fill in temporal gaps in the 2016 data. Version 2 also includes the application of a more aggressive filtering method, the correction of misnamed error values, and the addition of a west coast grid at 80.75 degrees north.

Access to the data and documentation is provided on the data set Web page at the NSIDC DAAC: http://nsidc.org/data/nsidc-0646
