The operational sea ice service at MET Norway produces high resolution sea ice concentration charts based on a manual interpretation of satellite data. The icecharts are updated every week day.
Satellite data used
SAR-dataThe main satellite data used are the weather independent Synthetic Aperture Radar data from the Radarsat-2 satellite. The Radarsat data are in scansar wide mode dual polarization. Each scene covers an area of 500 x 500 km and has a spatial resolution of approximately 50 meter. The scenes are mainly focused around the Svalbard and Barents Sea areas. For more info about SAR and interpretation see NOAA's "SAR Users Manual" at: http://www.sarusersmanual.com/
MODIS, NOAA and METOP dataIn addition to SAR data, we use visual and infrared data from METOP, NOAA and MODIS in cloud free conditions. These satellites data cover the charting area several times each day and are resampled to 1000 x 1000 meter.
MET Norway are running several sea ice models on a daily basis. The models have different time and spatial resolutions. A regional forecast product can be accessed from the "Main page". There is a continuasly work going on to improve the sea ice forecasting models. Pleace contact the ice service for more information.
