MEaSUREs Multi-year Reference Velocity Maps of the Antarctic Ice Sheet V001
https://cmr.earthdata.nasa.gov/search/concepts/C2274866095-NSIDC_ECS.xmlDescription:This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, consists of three as-complete-as-possible mosaic maps of velocities on the Antarctic ice sheet for the time periods 1995–2001, 2007–2009, and 2014–2017. The maps are posted at 450 m in the WGS 84/Antarctic Polar Stereographic projection. In addition to ice velocity, the data set provides maps of velocity error and standard deviation; counts of velocity estimates used per pixel; date ranges; and masks that delineate the ice fronts and grounding lines for the each period.

MEaSUREs Phase-Based Antarctica Ice Velocity Map V001
https://cmr.earthdata.nasa.gov/search/concepts/C1699753973-NSIDC_ECS.xmlDescription:This data set, as part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, combines interferometric phases from multiple satellite interferometric synthetic-aperture radar systems to derive the first comprehensive phase-based map of Antarctic ice velocity. The precision in ice speed and flow direction over 80% of Antarctica is better than prior mappings based on feature and speckle tracking by a factor of 10. Phase-derived velocity mostly covers the years between 2007 and 2018, while tracking-derived velocity (for regions along the coasts) is mostly found in the years from 2013 to 2017. Additional data acquired between 1996 and 2018 were used as needed to maximize coverage.

Modelling of microwave scattering in sea ice and radar image classification in Ross Island, Antarctica
https://cmr.earthdata.nasa.gov/search/concepts/C1214621883-SCIOPS.xmlDescription:This data set consists of ground truth measurements of sea ice in Ross Island, Antarctica. In the study of microwave remote sensing, field measurements or in-situ data collections play an important role towards verifying the accuracy of theoretical models. It is essential to understand the electrical property and structure of the medium that is to be scanned by the radar as these parameters greatly affect the microwave backscatter return signals. Measurement of the sea ice provides vital information to aid in the development and verification of the theoretical models. Furthermore, to better understand how the overlying snow layer influences microwaves, the overlying snow layer characteristics are also included in the measurements. Other parameters that are to be measured during the field trip are the air and ocean temperature as well as the ocean salinity. Fieldwork team performed ground measurements and took samples from areas surrounding Ross Island, Antarctica, including the front of Scott Base, McMurdo runway (United States), Willy's Field, Turtle Rock, Cape Evans and Cape Royds. Several locations were selected and the coordinate positions of the locations were acquired using the GPS system. In the ground measurements, 7 main parameters were identified and measured in the fieldwork. The 7 parameters are: Sea ice and snow cover thickness, Air, sea ice, snow and ocean temperature, Sea ice and snow density, Sea ice brine volume, crystal size and Orientation, sea ice, snow and ocean salinity, Sea ice and snow surface roughness and finally the site location coordinates. This field measurement results would later be used in the theoretical modelling of the snow and sea ice medium. The microwave Synthetic Aperture Radar (SAR) image at C-Band with HH polarization on the 27th of Oct 2005 had been requested from the Canadian Radarsat satellite.

Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH), Version 1
https://cmr.earthdata.nasa.gov/search/concepts/C1386246275-NSIDCV0.xmlDescription:The Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH) products provide measurements of daily sea ice extent and sea ice edge boundary for the Northern Hemisphere and 16 Arctic regions in a polar stereographic projection at both 1 km and 4 km grid cell sizes. MASIE products include an ASCII text file of sea ice extent values in square km for each Arctic region, time series plots, and image files that visually show where the sea ice is. Note: MASIE may look like several other sea ice products distributed at NSIDC and elsewhere, but its source data and intended uses are different. If intended and appropriate uses of the data are not clear after reading the documentation, please contact <a href="mailto:nsidc@nsidc.org">NSIDC User Services</a>.
