Description:

Seasonal air-sea carbon dioxide (CO2) flux maps were calculated from wind speed data and the difference in CO2 partial pressure between surface seawater (pCO2SW) and the overlying atmosphere. To infer the seasonal variability of global net air-sea CO2 fluxes over the last three decades, we derived the optimum subannual relationships between pCO2SW and the sea surface temperature (SST). These optimum subannual relationships accounted for the variations between pCO2SW and SST and showed significantly better correlations than previous relationships with fixed monthly boundaries. The derived algorithms were then applied to high-resolution SST data to yield changes in pCO2SW on a monthly basis. The pCO2SW values were also combined with a gas transfer velocity estimate derived from high resolution wind products to estimate seasonal fluxes. The seasonal fluxes that are calculated with a three- to six-month lag from real-time can be obtained at http://cwcgom.aoml.noaa.gov/erddap/griddap/aomlcarbonfluxes.graph. Here, we describe in detail the procedures and uncertainties of this product.
