Google Earth Engine——海洋热通量数据集是NOAA海洋表面束（OSB）的一部分，提供了无冰海洋上空气/海洋热通量的高质量的气候数据记录（CDR）。
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.

数据说明：
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 pdf.
