WHOI Objectively Analyzed Air-Sea Fluxes (OAFlux_V3)

Woods Hole Oceanographic Institute's objectively analyzed air-sea heat fluxes

Monthly 1° gridded global surface latent and sensible heat fluxes for the period from January 1958 to December 2006 have been developed and validated against in situ flux measurements. The product integrates satellite observations with surface moorings, ship reports, and atmospheric model reanalyzed surface meteorology and is developed by the OAFlux project (PIs. Drs. Lisan Yu and Robert A. Weller). The project is sponsored by the NOAA Office of Climate Observations (OCO) and Climate Change Data and Detection (CCDD). Further project information can be found at http://oaflux.whoi.edu.

Data in this release also include net longwave and shortwave radiations acquired from the International Satellite Cloud Climatology Project (ISCCP). This set of surface radiation data (three-hourly, 2.5-degree) is provided by Dr. William B. Rossow for distribution along with the OAFlux product. The ISCCP radiations have been monthly averaged and re-gridded onto the spatial and temporal resolution used by the OAFlux product, but only for 1983-2004. Information about the full, global ISCCP dataset can be found at http://isccp.giss.nasa.gov/projects/flux.html.
