Data download and acquisition could not occur simultaneously, consequently data gaps exist in the EASE-Grid data for Alaska and the Canadian Prairies from early 1994 until data acquisition by the DMSP-F13 SSM/I began in May 1995.
Nsidc: National Snow and Ice Data Center. doi: https://doi.org/10.7265/N5/Nsidc-GPC-2009-12. [Date Accessed]. Below is an excerpt from data file Ilatm2_20130424_183845_smooth_nadir3seg_50pt.csv. This data set contains Greenland and Antarctica gravity measurements taken from the Sander Geophysics AIRGrav airborne gravity system. The data are scaled instrument counts of the following: These data are not suitable for time series, anomalies, or trends analyses. They are meant to provide a best estimate of current ice and snow conditions based on information and algorithms available at the time the data are acquired. OpenSearch interface to a Solr backend.

The US National Snow and Ice Data Center (Nsidc) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and…

Waiscores researchers acquired and analyzed ice cores from the Siple Dome, in the Siple Coast region, West Antarctica.
Antarctic Grounding Line Mapping from Differential Satellite Radar Interferometry, Geophyical Research Letters. 38. This data set consists of brightness temperatures acquired from the Scanning Multichannel Microwave Radiometer (SMMR) on board the Nimbus-7 Pathfinder satellite. Ancillary data include time, geolocation, and quality assessment. On Wednesday, January 8th between 9 am and 9:30 am MDT, the following data collections may not be available due to planned system maintenance: AMSR-E, Aquarius, ASO, High Mountain Asia, IceBridge, Icesat/GLAS, Icesat-2, Measures, Modis… The NASA National Snow and Ice Data Center Distributed Active Archive Center (Nsidc DAAC) is pleased to announce that the Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-Ssmis Passive Microwave Data has been updated through 31… It was constructed by combining Aster and SPOT 5 DEMs over the ice sheet periphery and margin with Avhrr photoclinometry for the interior and far north, and calibrating the data to approximate mean Icesat/GLAS elevations from 2003 to 2009.
The image maps are constructed from Modis imagery acquired during 2005, 2010, and 2015 and provide nearly cloud-free views of all land areas and islands larger than a few hundred meters, including the ice caps on Baffin Island, Devon Island… It is derived from passive microwave satellite brightness temperature characteristics using the Cross-Polarized Gradient Ratio (XPGR) of Abdalati and Steffen (1997).
