#### Description

The Ocean Heat Fluxes dataset is part of the NOAA Ocean Surface Bundle (OSB)
and provides a high quality Climate Data Record (CDR) of the air/ocean heat
fluxes over ice-free oceans.

This dataset is calculated from the OSB CDR parameters of near-surface
atmospheric and sea surface temperature using a neural-network
emulator of the TOGA-COARE Bulk Air-Sea Flux Algorithm.

### Terms of Use

**Terms of Use**

The NOAA CDR Program's official distribution point for CDRs is NOAA's
National Climatic Data Center which provides sustained, open access and
active data management of the CDR packages and related information in
keeping with the United States' open data policies and practices as
described in the President's Memorandum on "Open Data Policy" and pursuant
to the Executive Order of May 9, 2013, "Making Open and Machine Readable
the New Default for Government Information". In line with these policies,
the CDR data sets are nonproprietary, publicly available, and no
restrictions are placed upon their use. For more information, see the
[Fair Use of NOAA's CDR Data Sets, Algorithms and Documentation](https://www1.ncdc.noaa.gov/pub/data/sds/cdr/CDRs/Aerosol_Optical_Thickness/UseAgreement_01B-04.pdf)
