This report describes the airborne part of the field work of the CryoSat Validation Experiment (CryoVEx) 2008 and the processing of the collected datasets. The airborne part of the campaign was carried out by DTU Space (former Danish National Space Center, DNSC) using a Twin Otter chartered from Air Greenland. The main purpose was to collect coincident ASIRAS and laser elevation data form validation sites on land and sea ice and in addition offer logistical support to ground teams. Overflights of corner reflectors were done at main validation sites in order to calibrate the ASIRAS data. The datasets from this campaign will be important for understanding the CryoSat-2 radar signals. The airborne part of CryoVEx 2008 was successfully carried out between April 15 and May 8 and the datasets have been stored and secured at DTU Space and Alfred Wegener Institute (AWI). Afterwards extensive data processing has been done by DTU Space and AWI in cooperation. This report describes the airborne system, the field work, and the data processing together with short descriptions of each validation site. The data from AWI’s helicopter electromagnetic sea ice sounder (EM bird) are included along with the field report of the sea ice in situ validation work carried out near Alert in May 2008.
