OVERVIEW OF OAFLUX PRODUCTS

 

The following two versions of OAFlux products are available.

  1. OAFlux-1° blended products: developed from optimal synthesis of satellite wind and SST observations and atmospheric reanalysis of air temperature and humidity. The products are available on 1° resolution from 1958 to the present. The project is sponsored by NOAA GOMO program.
  2. OAFlux-0.25° satellite products: developed from merging satellite observations from multiple sensors including scatterometers, radiometers, and sounders. he products are available on 0.25° resolution for the satellite era (1988 onward). The project is sponsored by NASA MeaSUREs program.

Note: The two versions of products are developed using different methodologies, different algorithms, and different source datasets. For more information about the differences between the two products, please read here. A summary of air-sea fluxes and variables contained in each product is provided below.
