| 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 a near high frequency (33-37 MHz) radar depth sounder in Greenland. An uninhabited aerial vehicle (UAV), dubbed the G1XB, was modified to carry this HF sounder. This dataset contains data collected at Russell Glacier in Greenland to demonstrate the system. This product uses unfocused synthetic aperture array (SAR) processing to improve resolution in along-track. The data product format is a Mathworks MATLAB file. Files are named according to the format: Data{$image_id}_{$frame_id}.mat. The {$image_id} is a string which may be empty when it is a composite image or is of the form “img_II” where II is the 2-digit zero-padded image number always starting with 1 and incrementing from there. 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. For example, “Data_20080627_05_001.mat” contains data for a composite image from segment 05, frame 001, taken on 2008-06-27. More information can be found in “Readme.pdf”.
