The Next Generation of Sea Surface Tempoerature Climate Data Records
Abstract
A new generation of integrated sea surface temperature (SST) data products are being provided by the Global Ocean Data Assimilation Experiment (GODAE) High-resolution SST Pilot Project (GHRSST-PP). These combine in near-real time various SST data products from several different satellite sensors and in situ observations and maintain fine spatial and temporal resolution needed by SST inputs to operational models. The practical realisation of such an approach is complicated by the characteristic differences that exist between measurements of SST obtained from subsurface in-water sensors, satellite microwave and satellite infrared radiometer systems. Furthermore, diurnal variability of SST within a 24 hour period, manifested as both warm layer and cool skin deviations, introduces additional uncertainty for direct inter-comparison of data sources and the implementation of data merging strategies. The GHRSST-PP has developed and now operates an internationally distributed system that provides operational feeds of regional and global coverage, high-resolution SST data products (better than 10 km and ~ 6 hourly). A suite of on-line satellite SST diagnostic systems are also available within the project. All GHRSST-PP products have a standard format, include uncertainty estimates for each measurement and, are served to the international user community free of charge through a variety of data transport mechanisms and access points. They are being used for a number of operational applications. The approach will also be extended back to 1981 by a dedicated re-analysis project. This paper provides a summary overview of the GHRSST-PP structure, activities and data products. For a complete discussion, access to data products and services see http:www.ghrsst-pp.org.
