Thermally induced mass coral bleaching has become a serious threat to coral reefs worldwide and is most often caused by anomalously elevated SSTs. In recent decades, coral reef ecosystems have been declining at alarming rates worldwide, with thermally induced coral bleaching being one of the most significant contributors to this increased deterioration. The need for improved understanding, monitoring, and prediction of coral bleaching is imperative. Satellite remote sensing, with its capability of providing synoptic views of the global oceans in near-real-time and its ability to monitor remote reef areas, has been an essential tool for coral reef managers, researchers, and other stakeholders worldwide. The NOAA CRW mission is to utilize remote sensing, modeled, and in-situ tools for near real-time and long-term monitoring, modeling and reporting of physical environmental conditions of coral reef ecosystems. CRW has been producing satellite SST-based global (and regional) products to monitor thermal conditions conducive to coral bleaching and assess the severity of coral bleaching since 1997. This effort was carried out originally using CRW’s twice-weekly 50km global coral bleaching product suite. It has been enhanced with CRW's next-generation, daily global 5km product suite, available since 2012 and currently in Version 3.1, as documented in this metadata file. The next-generation 5km products significantly advance CRW's capability for near real-time satellite coral bleaching heat stress monitoring, as compared with CRW’s heritage twice-weekly 50km global coral bleaching product suite. This Version 3.1 suite, in particular, was developed based on user requests for a longer time series of comparable CRW 5km products, and to address errors identified in the operational daily global 5km Geo-Polar Blended Night-only SST Analysis for some coral reef regions during 2013-2016. CRW’s satellite products have been used extensively by coral reef ecosystem managers, scientists, and other stakeholders to guide their management practices, reef conservation and protection initiatives, public outreach campaigns leading up to and during major bleaching events, in-situ surveys, research efforts, and more. With significantly higher spatial and temporal resolutions in the 5km products, CRW can provide service at or close to the scale of coral reefs, allowing direct monitoring of 95% of global coral reefs and significantly reducing data gaps caused by cloud cover.
