Description
Summary:To better understand processes affecting the ice sheets and to supply boundary condition information into ice sheet models and ice thickness for other ice sheet analysis, the Center for Remote Sensing of Ice Sheets (CReSIS) has designed, developed, and deployed several multichannel radar depth sounders in Greenland. This dataset contains data collected mostly around outlet glaciers in Greenland, including a large grid at Jakobshavn, with the specific purpose of improving understanding in this dynamic and fast changing part of the ice sheet. Using this radar dataset, various manual and semi-automated techniques are used to track the ice surface and ice bottom in the echogram data products. The ice surface and ice bottom are stored in comma separated values (CSV) format files. Files are named according to the format: Data_{$frame_id}_HHmmss.csv. The frame ID is a concatenation of the segment ID and a frame number and follows the format YYYYMMDD_SS_FFF where FFF is the frame number from 000 to 999. HHmmss is the GPS time stamp for the first range line in the csv file where HH is 00-23 hours, mm is 00-59 minutes, and ss is 00-59 seconds. For example, “Data_20080627_05_001_164310.csv” contains data from segment 05, frame 001, and is from 2008-06-27 starting at 16:43:10. “2008_Greenland_TO.csv” contains all the individual frames from the whole season concatenated together.
