IMPROVED SEA-ICE MONITORING FOR THE BALTIC SEA: PROJECT OVERVIEW AND FIRST RESULTS

摘要

In 2007 a field campaign was conducted in the Gulf ofrnBothnia. The aim was to collect validation data for anrnevaluation of the possibilities to use SAR data from thernALOS satellite for sea-ice monitoring. This paper givesrnan overview of the field campaign, collected data andrnthe first results. A comparison between ScanSARrnimages from ALOS and Envisat indicate that the mainrnice features can be seen in both image types. An initialrnanalysis also shows that the L-band backscatter fromrnopen water is less sensitive to wind in the crosspolarizedrnthan in the co-polarized channels.
