Composite Datasets Product Description

Presented here are year-to-date (for the current year), monthly, and annual composites of the NOAA Coral Reef Watch (CRW) experimental daily global 5-km (0.05 degree) satellite coral bleaching heat stress monitoring products. The high-resolution 5-km daily products are based on the NOAA/NESDIS operational daily global 5-km Geo-Polar (geostationary-polar-orbiting) Blended Night-only SST Analysis and currently include sea surface temperature (SST), SST Anomaly, Coral Bleaching HotSpot, Degree Heating Week (DHW), and Bleaching Alert Area products. The maximum composites are available for all of these variables; minimum and mean composites are available only for SST and SST Anomaly because the Bleaching Alert Area, DHW, and HotSpot are positive-value-only products. Click on the link below for more details about the 5-km product suite.

 

Development of the next-generation 5-km product suite has been accomplished through a collaboration of NOAA Coral Reef Watch, the University of South Florida, NASA-Ames, the UNEP World Conservation Monitoring Centre, and the Cooperative Institute for Research in Environmental Science, with funding support from the NASA Biodiversity and Ecological Forecasting program, the NOAA Coral Reef Conservation Program, and the NOAA/NESDIS Ocean Remote Sensing Program. The 5-km product suite, which was featured in the NASA Applied Sciences Program's 2013 Annual Report, will undergo continuous improvements.

CRW will continue to produce the current operational 50-km product suite until the 5-km product suite becomes operational. As noted above, there will be some differences between the two product suites in certain areas, and user discretion is advised. We expect that the 5-km product suite will be more accurate due to the improved data quality, density, spatial and temporal resolutions, and climatology.
