Global Daily Sea Ice Concentration Reprocessing Data Set for 1978-2007 from the EUMETSAT Ocean and Sea Ice Satellite Application Facility (NODC Accession 0068294)

These data constitute the reprocessed sea ice concentration data set from the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF), covering the period from 1978-2007, with data from the Scanning Multichannel Microwave Radiometer (SMMR) and the Special Sensor Microwave/Imager (SSM/I). The data set provides daily, global coverage at 10 km and 12.5 km spatial resolution. Ice concentration is computed from atmospherically corrected brightness temperatures, using a combination of state-of-the-art algorithms and dynamic tie-points. The data set includes uncertainty estimates for each grid cell (error estimates). Version 1 of the data set was released in early 2010.

ABOUT THE PROJECT:
Sea ice is a part of our changing climate system. Continuous monitoring of sea ice globally on a daily basis started with the launch of SeaSat in June 1978 and Nimbus-7 in October of the same year, both with a SMMR instrument on board. SMMR was the first multi-frequency and dual polarization microwave radiometer satellite instrument which was particularly well suited for sea ice monitoring. American satellite microwave radiometer instruments still provide sea ice observations today in an unbroken record since 1978. The Nimbus-7 SMMR brightness temperature data from October 1978 to August 1987 was provided by OSI-SAF's partner in the project, the U.S. National Snow and Ice Data Center (NSIDC). EUMETSAT purchased the DMSP SSM/I data from Remote Sensing Systems.

EUMETSAT initiated the reprocessing of both microwave radiometer datasets in 2005 and the OSI-SAF team developed a new processing chain and selected new algorithms. The initial development has been done in cooperation with the Met Office and NSIDC. Further development is ongoing. Both the SMMR and SSM/I data sets from October 1978 to December 2007 for both hemispheres have been processed using a sea ice concentration algorithm and methodology which is consistent for all 7 sensors throughout the time series. The first version of the global sea ice concentration data set was complete in 2010. Updates are planned with current satellites.

DATA SET INFORMATION:
The data are available in two projections: Polar Stereographic and Lambert Azimuthal Equal Area. Polar Stereographic files are at 10km spatial resolution, and Lambert Azimuthal Equal Area files are at 12.5km spatial resolution. Both projections are stored in two files per day; one each for the Northern and Southern Hemispheres. All files are in Climate Forecast-compliant netCDF format.

CITATION INFORMATION:
When using these data, please acknowledge EUMETSAT by referring to:

These data are used as the auxiliary sea ice field for the AVHRR Pathfinder Version 6 Sea Surface Temperature product, which is produced as part of the Group for High Resolution Sea Surface Temperature (GHRSST).
Purpose Sea ice is part of our changing climate system. Continuous monitoring of global sea ice on a daily basis started with the launch of SeaSat in June 1978 and Nimbus-7 in October of the same year, both carrying the scanning multichannel microwave radiometer instrument. Since the start of the operational production of sea ice products in 2002, the growing user base has brought more focus on expanding the available data set. As a result, in 2006 EUMETSAT began an effort to reprocess historical passive microwave data to extend the OSI SAF sea ice data set.
