NOTICE: There is currently a delay in updating the data for the Global Hourly and Daily Summary data. We are working to resolve the issue.

Blended and Global

We produce various high-level datasets and products that are generated by blending together observations from various platforms and instruments, as well as by merging data over different geographic domains, for example, over both land and ocean surfaces for globally covered products. Datasets and products in this category include those listed below.

  • NOAA Global Surface Temperature (NOAAGlobalTemp)
    NOAAGlobalTemp is a globally gridded surface temperature dataset that is generated by blending surface air temperature over land and sea surface temperature over the ocean.
  • Optimum Interpolation Sea Surface Temperature (OISST)
    OISST is a gridded global sea surface temperature dataset with 0.25° spatial resolution and daily time resolution that is generated by blending observations from satellites with those from ships and buoys (both moored and drifting).
  • Blended Sea Winds
    The Blended Sea Winds dataset contains globally gridded, high-resolution ocean surface vector winds and wind stresses on a global 0.25° grid, with multiple time resolutions of six-hourly, daily, monthly, and 11-year (1995–2005) climatological monthlies, generated by blending observations from multiple satellite instruments and model simulated wind directions.
  • Climate Monitoring Indices
    These climate monitoring indices are computed from various global blended and merged datasets.
  • The Global Observing Systems Information Center (GOSIC)
    The GOSIC Portal is hosted at NCEI and provides an information center that facilitates the search of and access to data, products, metadata, and information for the Global Climate Observing System (GCOS).
  • The World Data Center for Meteorology, Asheville
    The World Data Center (WDC) for Meteorology, Asheville is hosted by and operated in conjunction with NCEI, in accordance with the principles set forth by the ICSU World Data System (WDS).  The WDC for Meteorology, Asheville acquires, catalogs, and archives data and makes them available to users in the international scientific community as well as to the general public. Data are exchanged with counterparts, including the WDC for Meteorology, Obninsk and WDC for Meteorology, Beijing as necessary to improve access to climate and weather data.  The WDC for Meteorology, Asheville, was a founding member of the WDS in 2011 and was a member of the predecessor to the WDS dating back to the 1960s.
