Icechart (manual analysis) (ice.ice_chart)
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 daily from Monday to Friday. 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. In addition to SAR data, visual and infrared data from METOP, NOAA and MODIS in cloud free conditions are used. 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). The scenes are mainly focused around the Svalbard and Barents Sea areas, but when needed charts are also made for the Norwegian coastline, i. e. Oslofjorden. Every Monday and Thursday charts for Antarctic are made.

Automatic sea ice analysis from SAR data (ice.ice_analysis_sar)
Automatic sea Ice analysis based on high resolution satellite data from Radarsat-2. The product is generated from an Bayesian approach witch utilize HH and HV polarization to separate ice and water. From this classification the ice concentration is calculated by counting number of ice points in an area of 1x1 km. Each analysed Radarsat-2 image are compiled into a daily mosaic image which are updated when a new image is received and analysed at the ice service.

Sea ice concentration statistics from MET NORWAY ice charts (iskart.konsentrasjon)
This monthly sea ice statistics is based on ice charts produced by the Norwegian ice service at the Meteorological institute. The products have a spatial resolution of 4 x 4 km and give a mean ice concentration in concentration intervals defined by the World Meteorological Organisation (WMO). The ice charts are produced at the operational sea ice service at MET Norway. They produces high resolution sea ice concentration charts based on a manual interpretation of satellite data. The icecharts are updated Monday to Friday. 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. In addition to SAR data, visual and infrared data from METOP, NOAA and MODIS in cloud free conditions are used. These satellites data cover the charting area several times each day and are resampled to 1000 x 1000 meter. The icecharts are updated daily from Monday to Friday. This service is developed in cooperation with BarentsWatch.no
Strike Probability (strike_probability)
Maps showing probability of the path of a polar low hitting an area in the next 42 hours. The product is updated four times per day. The map is based on the AROME-Arctic numerical model with 2.5 km horisontal resolution. This service is developed in cooperation with BarentsWatch.no
