【 摘 要 】

The CryoClim project has developed a new operational and permanent service for long-term systematic climate monitoring of the cryosphere. The product production and the product repositories are hosted by mandated organisations, and the service is delivered through a state-of-the-art web service and web portal. The service provides sea ice and snow products of global coverage and glacier products covering Norway (mainland and Svalbard). The sea ice sub-service is based on data from passive microwave radiometers (SMMR and SSM/I). The same period is covered by snow cover extent products based on passive microwave radiometers (SMMR and SSM/I) and optical (AVHRR from 1982). Glacier maps, including glacier area outline and glacier lakes have been generated from Landsat TM, ETM+ and historic topographic maps for all glaciers in mainland Norway starting the time series from 1952. For Svalbard, glacier products are based on optical data (SPOT and MODIS) for glacier area outline and glacier snow line, and SAR data (ERS-1, ERS-2, Envisat ASAR and Radarsat) for glacier surface type. The period covered with satellite data starts in the early 1990s. The glacier area outline time series has in Svalbard also been extended with map data and aerial images from earlier days.
