NASA Earthdata CMR2026 · Raster · GeoTIFF

This data set contains grounding lines for major glaciers and ice shelves in East Antarctica, West Antarctica, and the Antarctic Peninsula, plus corresponding Differential Interferometric Synthetic Aperture Radar (DInSAR) interferograms (phase and coherence), generated from X-band SAR data acquired by the COSMO-SkyMed mission between 30 April 2020 and 10 June 2022.

NASA Earthdata CMR + NASA Data Portal2026 · Image data

This dataset provides global, wall-to-wall estimates of the Waveform Structural Complexity Index (WSCI) at 25-meter spatial resolution with 3-monthly temporal frequency from 2015 to 2022. The product advances the sparse footprint-level GEDI L4C product by using deep learning to fuse spaceborne lidar observations with multi-sensor Synthetic Aperture Radar (SAR) data, producing spatially continuous

NASA Earthdata CMR2022 · Array · NetCDF

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains four, as-complete-as-possible 450 m resolution reference maps of ice component velocities for the Antarctic ice sheet. Maps are available for 1995 – 2001; 2007 – 2009; 2014 – 2017; and 2020 – 2022. Velocities are derived by applying phase analysis and speckle tracking to s

NASA Earthdata CMR2021 · Image data

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides velocity estimates determined from Interferometric Synthetic Aperture Radar (InSAR) data for major glacier outlet areas in Greenland, some of which have shown profound velocity changes over the MEaSUREs observation period. The InSAR Selected Glacier Site Velocity Maps are

NASA Earthdata CMR2020 · collection

ICEYE full archive and new tasking products are available in Strip, Spot, SLEA (Spot Extended Area), Scan, and Dwell modes: • Strip instrument mode: the ground swath is illuminated with a continuous sequence of pulses while the antenna beam is fixed in its orientation. This results in a long image strip parallel to the flight direction: the transmitted pulse bandwidth is adjusted to always achieve

NASA Earthdata CMR2018 · collection

The ICEYE ESA archive collection consists of ICEYE Level 1 products requested by ESA supported projects over their areas of interest around the world. The dataset regularly grows as ESA collects new products over the years. Three different modes are available: • Spot: with a slant resolution of 50 cm in range by 25 cm in azimuth that translated into the ground generates a ground resolution of 1 m

NASA Earthdata CMR2016 · collection

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides comprehensive high-resolution mapping of grounding lines in Antarctica from February 1992 through November 2025. The data were derived by applying differential satellite synthetic aperture radar (SAR) interferometry (DInSAR) to SAR data acquired by various space-based plat

NASA Earthdata CMR2000 · Image data

Culminating more than four years of processing data, NASA and the National Geospatial-Intelligence Agency (NGA) have completed Earth's most extensive global topographic map. The mission is a collaboration among NASA, NGA, and the German and Italian space agencies. For 11 days in February 2000, the space shuttle Endeavour conducted the Shuttle Radar Topography Mission (SRTM) using C-Band and X-Band

The Space Radar Laboratory-1 (SRL-1) was a payload launched with the Space Shuttle &Endeavor& (STS-59) on April 9, 1994. The SRL-1 comprises two elements: a suite of radar instruments called the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR), and the Measurement of Air Pollution from Satellite (MAPS) instrument. The SIR-C/X-SAR radar was jointly developed by NASA with DAR
