Detailed Data Description

The IceBridge DMS L0 Camera Calibration files contain DMS camera calibration summary reports in PDF format for missions flown over Antarctica and Greenland.

The Camera Calibration Report summary PDF files include the lens characterization of the instrument, i.e., the lens camera-body-specific distortion. DMS is currently on its 23rd camera (late 2016), and there is a new calibration for each camera. The science team found that after about 400,000 exposures, the camera life degraded to the point where even after maintenance the camera was no longer usable for mission purposes, so a new camera was obtained to carry on with the next campaigns. Table 1 lists the calibration reports for each IceBridge DMS campaign. There are one or two calibration summary files per campaign. If the primary camera failed during the campaign and the second camera was used, there are two files for that campaign.
