Abstract:
In this presentation we present the comprehensive ocean surface datasets and services and the most recent progresses at the NOAA National Centers for Environmental Information (NCEI). NCEI provides scientific stewardship for climate and oceanographic data in six conceptual levels/tiers, from basic long-term preservation and basic data access to enhanced data access and basic quality control, scientific improvements, derived products (e.g. blended and gridded products), authoritative records (e.g., a Climate Data Records), and finally to national services and international leadership. NCEI’s comprehensive ocean surface datasets and services encompass all six tiers of NCEI’s scientific data stewardship. Examples include the in-situ observation based foundational datasets, such as the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) and its near-real-time version from GTS data collection, the Thermosalinograph (TSG) database, and the centennial scale (1854-present) monthly Extended Reconstructed Sea Surface Temperature (ERSST). Higher-tier examples include the modern time satellite observation based Pathfinder Sea Surface Temperature (PFSST), the blended Optimum Interpolation Sea Surface Temperature (OISST) combining observations from in-situ and satellite platforms, the multi-satellite blended sea surface winds, the collection of altimeter and sea level data, and the gridded sea surface salinity, among others.. NCEI also serves as the Long Term Stewardship and Reanalysis Facility (LTSRF) for the GHRSST. We present the user community an update on the most recent improvements to these datasets and services, such as the development of an updated ICOADS near-real-time product of merged ASCII/TAC and BUFR, development of ERSST ensemble uncertainty estimates, new capacity of near-real-time updates to the PFSST, OISST improvements in Arctic Region, and expanded GHRSST collection and services. Most recent improvements in the above will be described.
