Response of passive microwave sea ice concentration algorithms to thin ice

The influence of sea ice thickness brightness temperatures and ice concentrations retrieved from passive microwave observations is quantified, using horizontally homogeneous sea ice thickness retrievals from ESAs SMOS sensor observations at high incidence angles. Brightness temperatures are influenced by thickness below 18 cm (89GHz) and 50 cm (1.4 GHz). Ice concentration retrievals reduced by ice thickness below 0.17 m and 0.33 m, with higher frequency algorithms being less influenced.

Sentinel-1 results: Sea ice operational monitoring

In the present paper we demonstrate the capabilities of the Sentinel-1 SAR data for operational sea-ice and iceberg monitoring. Most of the examples are drawn from the Copernicus Marine Environmental Monitoring Service (CMEMS) production.

IWICOS: Integrated Weather, Sea Ice and Ocean Service System

Abstract The objective of IWICOS is to develop a prototype marine information system that will provide end-users with a single-entry access point to meteorological, sea ice and oceanographic data and products in electronic form for users of operational services. These include national ice and weather services, shipping companies and sea traffic adminis- tration, icebreaker captains and ice pilots of ships, oil companies and offshore industry, fishing vessels and other ships operating in harsh climate, and finally climate research, education and media. The core elements of the IWICOS system are standardised formats (BSQ, GRIB, Shapefile and XML) a common metadata definition, a producer server, a broker, and facades that allow different client software to interact with the system. Practical demonstrations and evaluation of the IWICOS system have been performed for selected end-users during 2002. More information can be found on http://www.nersc.no/Mwicos
