Reynolds NCEP Level 4 Optimally Interpolated SST Weekly Version 1

DescriptionThe NOAA/NCEP Reynolds Optimally Interpolated (OI) Sea Surface Temperature weekly Level 4 product consists of aggregate 7 day global sea surface temperature fields on a 1 degree by 1 degree grid. The OI analysis employed uses both in-situ SSTs from ships and buoys and satellite derived SSTs from the NOAA Advanced Very High Resolution Radiometer (AVHRR). The satellite derived SSTs are from the Multichannel Sea Surface Temperature products that have been constructed operationally from the five-channel AVHRR by NOAA's Environmental Satellite, Data, and Information Service (NESDIS) since late 1981 through to 2002. This SST OI Version 1.0 weekly product has been available since 1993 and is widely used for weather and climate monitoring and forecasting.
