Title: Mircowave remote sensing scattering parameters
Description:
Abstract:
This data set consists of ground truth measurements of snow and sea ice in Ross Island, Antarctica. In the study of microwave remote sensing, field measurements or in-situ data collections play an important role towards verifying the accuracy of theoretical models. It is essential to understand the electrical property and structure of the medium that is to be scanned by the radar as these parameters greatly affect the microwave backscatter return signals. Measurement of the sea ice provides vital information to aid in the development and verification of the theoretical models. Furthermore, to better understand how the overlying snow layer influences microwaves, the overlying snow layer characteristics were also included in the measurements. The fieldwork team performed ground measurements and took samples from areas surrounding Ross Island, Antarctica, including the front of Scott Base, McMurdo runway (United States), Willy's Field, Turtle Rock, Cape Evans and Cape Royds. Several locations from the stated areas were selected and the coordinates were acquired using the GPS system. 7 main parameters were identified and measured in the fieldwork. The 7 parameters were: Sea ice and snow cover thickness; air, sea ice, snow and ocean temperature; sea ice and snow density; sea ice brine volume, crystal size and orientation; sea ice, snow and ocean salinity; sea ice and snow surface roughness and finally the site coordinates. The field measurement results would later be used in the theoretical modelling of the snow and sea ice medium. A Radarsat image of Ross Island with HH polarization on the 19th of October 2006 had been requested. In addition, an ERS satellite image of Ross Island with VV polarization on the 18th of October 2006 had also been requested. These images will be used together with the field measurement results to verify the theoretical models researched.
