The operational sea ice service at met.no produces high resolution sea ice concentration charts based on a manual interpretation of satellite data. The 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.
MODIS, NOAA and METOP data
In 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. The operator uses the latest available satellite data to manually analyse and classify areas of different concentrations based on the concentration intervals defined by the WMO (World Meteorological Organization).
A new sea ice concentration product is available every weekday around 1400 GMT.
- Latest updated ice chart are available at http://polarview.met.no/clickmap.htm
- The ice charts are also available as a WMS layer at http://wms.met.no/icechart/
- Historical ice charts back to 1998 can be found at http://126.96.36.199/archive/
- met.no also runs different sea ice models showing the expected ice development. One model that uses the ice charts an initial start and derives a 24 hours forecast with a horizontal resolution of 2 km can be found her http://polarview.met.no/regs/f24.png
