CORE.2 Global Air-Sea Flux Dataset

This dataset contains the complete set of global air-sea heat and water flux components computed from version 2 of CORE (Common Ocean Reference Experiment) atmospheric state fields starting from 1949. The air-sea fluxes are derived from bulk formulae applied to atmospheric state fields from multiple sources together with a merged Hadley-OI SST product at monthly resolution. The primary atmospheric input data are based on NCEP reanalyses at 6-hourly resolution. In addition, satellite-based radiation, precipitation, and sea ice concentration are used, at resolutions from daily to monthly. Some of the input data have been adjusted to agree in the mean with a variety of more reliable satellite and in situ measurements that themselves are either too short in duration or too regional in coverage. Fluxes have been temporally averaged as needed for distribution as monthly means.
