Ice and sea surface temperature in the Arctic Ocean
Daily updated ice temperature from satellite observations
The ice surface temperature strongly affects heat exchange between the surface and the atmosphere and the rate
of ice growth. In order to perform proper forecasting of weather and sea-ice conditions, it is essential to obtain accurate surface temperatures.
A sparsely distributed observational network, consisting of drifting buoys, cannot resolve the surface temperature
variations in the Arctic sufficiently but satellite observations can fill in the gaps of the traditional observational network.
The DMI ice temperature product (IST) uses three thermal infrared channels from the Advanced Very High Resolution
Radiometer (AVHRR) on board the Metop-A satellite to calculate the surface temperatures in the Arctic.
