This is the most recent version of these data.
Version 2 data provide an improvement of the geolocation of the KT-19 footprints, due to replacing the coarse real-time GPS positions with post-processed differential GPS positions. The post-processed trajectories are the same as used for the ATM lidar processing. The user is encouraged to use Version 2 data.
Version 1 data additionally provide data from the National Suborbital Research Center (NSRC), which extend the spatial and temporal coverage.
This data set contains surface temperature measurements of Arctic and Antarctic sea ice and land ice acquired by the Heitronics KT19.85 Series II Infrared Radiation Pyrometer. The instrument is operated by the Wallops Flight Facility (WFF) as part of the ATM instrument suite. The data were collected as part of the Operation IceBridge funded survey campaigns.
Many NSIDC data set web pages provide the ability to search and filter data with spatial and temporal contstraints using a map-based interface. This article outlines how to order NSIDC DAAC data using advanced searching and filtering.
