NOAA NCDC participates in both of the projects and serves as the central archive for the SURFA datasets. In addition to the NCEP archive at NCDC by NOMADS, the archive currently includes the in situ data from the OceanSITES reference stations, and NWP model output from ECMWF and German DWD. Satellite-based turbulent air-sea heat fluxes and related parameters are also being developed at NCDC. These include the global 0.25-degree sea winds and sea surface temperatures blended from multiple satellites and in situ observations, and retrievals of sea surface air temperature and humidity using a neural-network approach from the AMSU measurements onboard the NOAA polar orbiting satellites. Both the SURFA datasets and the NCDC satellite-based datasets are available in user friendly formats at http://www.ncdc.noaa.gov/oa/satellite.html.
