    Heat flux freshwater (evaporation) momentum

    OAFlux datasets:

    (1) Turbulent latent and sensible heat fluxes analysis (ftp sites: daily monthly Plots)

    The OAFlux project provides near-realtime 1-degree global analysis for the following variables from
    January 1958 onward:
    • Latent heat flux 102               (W/m2, positive upward)
    • Sensible heat flux  102           (W/m2, positive upward)
    • Wind speed at 10m 2             (m/s)
    • Air specific humidity at 2m      (g/kg)
    • Air temperature at 2m 4         (C)
    • Sea surface temperature        (C)
    • Error fields estimates for all the six variables
    • ISCCP net downward shortwave radiation on OAFlux grids (W/m2, positive downward)
    • ISCCP net downward longwave radiation on OAFlux grids (W/m2, positive upward)
    (The surface radiation from ISCCP-FD datasets (3-hourly, 2.5 -degree) is kindly
         provided by Dr. William B. Rossow for distribution along with the OAFlux products)
    • Net heat fluxes (OAFlux+ISCCP) over the global oceans (W/m2, positive downward)
    (2) Ocean evaporation (ftp sites: daily monthly Plots)

    The OAFlux project provides near-realtime 1-degree global analysis for the following variables from
    January 1958 onward:
    • Evaporation (cm/yr, positive upward)
    • Error fields estimate
    (3) High-resolution momentum flux analysis (daily, monthly, plots)

    The OAFlux project provides 0.25-degree global analysis for the following variables from July 1987
    onward):
    • wind speed at 10m                      (m/s)
    • zonal wind at 10m                       (m/s, positive eastward)
    • meridional wind at 10m               (m/s, positive northward)
    • Error field estimates for wind speed, zonal and meridional winds
    • wind stress magnitude                (N/m2)
    • zonal wind stress                        (N/m2, positive eastward)
    • meridional wind stress                (N/m2, positive northward)
    • wind stress curl                           (N/m3 , positive upward)
    • convergence/divergence             (s-1, positive upward)
    • convergence/divergence             (s-1, positive upward)
    • The wind and momentum flux products on 1-degree grid are also made available to support the 1-degree global heat flux analysis. The 1-degree products are the 16-point averages of the 0.25-degree products.
