NASA 2015_AK_UAF Project

This data set contains radar echograms acquired by the University of Alaska Fairbanks High-Frequency Radar Sounder over select glaciers in Alaska. IRUAFHF2 This data set contains measurements of glacier surface elevation, bed elevation, and ice thickness for Alaska and Northwestern Canada. Glacier surface elevation is derived from IceBridge UAF Lidar Scanner L1B Geolocated Surface Elevation Triplets (ILAKS1B). Radar bed returns are sourced from IceBridge UAF L1B HF Geolocated Radar Echo Strength Profiles (IRUAFHF1B) to provide glacier bed elevation and ice thickness. Radar-derived ice thickness and glacier bed elevation are provided as per-trace measurements from the corresponding L1B radar echo strength profile (referencing the WGS 84 ellipsoid). Data Discovery Explore this data using NASA's Earthdata Search, a comprehensive tool for discovering and visualizing Earth science datasets. Data Access Access requir[...]

This data set contains flight reports from NASA Operation IceBridge Greenland, Arctic, Antarctic, and Alaska missions. Flight reports contain information on region, mission, aircraft model, flight data, purpose of flight, and on-board sensors. The flight reports were collected as part of Operation IceBridge funded aircraft survey campaigns. The corresponding flight lines can be found in the IceBridge L1B Thinned Flight Lines (IPFLT1B) data set. ILAKP1B This data set contains surface profiles of Alaska Glaciers acquired using the airborne University of Alaska Fairbanks (UAF) Glacier Lidar system. The data were collected as part of Operation IceBridge funded aircraft survey campaigns. ILAKS1B This data set contains scanning laser altimetry data points of Alaskan glaciers and parts of East and West Antarctica acquired by the airborne University of Alaska Fairbanks (UAF) Glacier Lidar system. The data were collected as part of NASA Operation IceBridge funded camp[...]

This data set represents a collection of orthorectified images that were created using the NASA Ames Stereo Pipeline. The final images were obtained by processing stereo images from the IceBridge DMS L0 Raw Imagery data set, along with NASA's Land, Vegetation, and Ice Sensor (LVIS) and Airborne Topographic Mapper (ATM) lidar data from the IceBridge LVIS L2 Geolocated Surface Elevation Product and IceBridge ATM L1B Elevation and Return Strength data sets, respectively. The closely related data set IceBridge DMS L3 Ames Stereo Pipeline Photogrammetric DEM provides the corresponding digital elevation models (DEMs) in GeoTIFF format. IODEM3 This data set represents a collection of digital elevation models (DEMs) that were created using the NASA Ames Stereo Pipeline. The final DEMs were obtained by processing stereo images from the IceBridge DMS L0 Raw Imagery data set, along with NASA's Land, Vegetation, and Ice Sensor (LVIS) and Airborne Topographic Mapper (ATM) lidar data[...]

This data set, part of the NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides a complete 15 m resolution image mosaic of the Greenland ice sheet, derived from USGS Landsat 7 ETM+ imagery and Canadian Space Agency's (CSA) RADARSAT-1 imagery from the years 1999 to 2002. Additional bands (some at 30 m resolution) are provided for each tile in the mosaic and are useful for understanding surface properties, such as snow grain size, bedrock outcrops, mapping layering in the snow, and blue ice or lake-filled regions, during the spring and summer months. The panchromatic (band 8) mosaic provides the highest-resolution view of the ice sheet surface at 15 m, resolving topographic features, large crevasses, and other geophysical structures. See Greenland Ice Mapping Project (GIMP) for related data. NSIDC-0714 This data set, part of the NASA Making Earth System Data Records for Use [...]
