MEaSUREs Greenland Ice Sheet Mosaics from SAR Data

Calibrated and uncalibrated radar backscatter was used to create ice-sheet-wide image mosaics. The 20 m resolution mosaic consists of 25 tiles.

GIMP Data

The objective of the Greenland Ice sheet Mapping Project (GIMP) is to establish benchmark data sets for observing ice sheet change and stability. Utilizing data from a variety of satellites and sensors, including Landsat-7, Landsat-8, TSX, RADARSAT-1, and RADARSAT-2, the acquired data covers multiple years, beginning in 2000. These data include ice-sheet-wide ice velocity, surface elevation, and surface morphology maps.

The following data sets were generated by the GIMP project, which is funded through NASA's Making Earth System data records for Use in Research Environments (MEaSUREs) program. The GIMP project principle investigators are Ian Joughin of the Applied Physics Laboratory and Ian Howat of the Byrd Polar Research Center.
