OAFlux 1° Analysis of 60+ Years
- OAFlux global ocean evaporation, latent/sensible heat fluxes, and related surface meteorology have been updated to 2021-MAR-31.
(1) 1° gridded daily-mean (1985 onward) and monthly-mean (1958 onward):
- latent heat flux (positive upward)
- sensible heat flux (positive upward)
- wind speed at 10m
- sea surface temperature
- air temperature at 2m
- air specific humidity at 2m
- error field estimates for all the six variables
(2) ISCCP radiation products interpolated onto OAFlux 1° grids:
- net surface shortwave radiation (positive downward)
- net surface longwave radiation (positive upward)
- The ISCCP datasets (7/1/1983-12/31/2009) are kindly provided by Dr. William B. Rossow for distribution along with the OAFlux products.
- The ISCCP datasets available here are on the OAFlux daily and 1-degree grid. The ISCCP original data products are gridded on 3-hourly, 2.5-degree resolution.
- Work is underway on developing surface shortwave and longwave radiation analysis that balances the OAFlux surface turbulent heat fluxes.
(3) Net heat flux (1-degree gridded daily- and monthly-mean (1985-2009)):
- net heat flux (positive downward, combined OAFlux and ISCCP)
