File and Directory Structure

Data files are on the FTP site https://n5eil01u.ecs.nsidc.org/icebridge/iodms0.001/ in folders organized by year and location, for example /2009_AN_NASA/ and /2016_GR_NASA/, where AN = Antarctica, and GR = Greenland.

Sub-directories containing raw JPEG images are named by month (MM), day (DD), and year (YYYY), for example /03142013_raw/.

DMS Camera Calibration Summary

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

The Camera Calibration Report summary PDF files include lens characterization of the instrument, that is, the lens camera-body-specific distortion. DMS is currently on its 23rd camera (Late 2016), and there is a new calibration for each camera. Typically 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.

Data Acquisition and Processing

Data Acquisition Methods

DMS is a visible imaging system, capturing data throughout flight. Level-0 products for raw DMS include raw JPEG files. Most imagery were acquired in panchromatic mode, but all provided output is 3-banded imagery.

Background color on
Sensor or Instrument Description

The DMS airborne digital camera acquires high resolution natural color and panchromatic imagery from low and medium altitude research aircraft. The system configuration includes a 21 megapixel Canon EOS 5D Mark II digital camera, computer-controlled intervalometer, and an Applanix POS/AV precision orientation system. In-flight operators maximize image quality with adjustments to exposure and intervalometer settings.
