The heritage 50km products served the U.S. and international coral reef communities for more than 20 years (1997-2020) as the only global early-warning system of coral reef ecosystem physical environmental changes. These near real-time products successfully and accurately monitored and predicted all major mass coral bleaching events observed globally since 1997, while also providing other critical information to users, especially during times of high heat stress. They helped resource managers, scientists, decision makers (including elected officials), and the public monitor climate impacts to reef ecosystems worldwide; enhance understanding of links between environmental conditions and ecosystem impacts; assess when reefs were vulnerable or resilient to climate change and its impacts (especially bleaching); and prepare and prioritize resources to implement timely, effective protective responses and adaptation actions (including restoration efforts), helping improve coral reef management and regulation in a warming world. With the retirement of the twice-weekly global 50km satellite coral bleaching heat stress monitoring products, NOAA CRW is still providing an archive of the 50km data and images for the following products: Sea Surface Temperature (SST), SST Anomaly, Coral Bleaching HotSpot, coral bleaching Degree Heating Week, Bleaching Alert Area, monthly and annual composites of the 50km products, and the 50km Virtual Stations. The 50km monthly mean satellite-only nighttime SST climatologies for all 12 months, and the maximum of those monthly mean climatologies are also available. Archived 50km data and images are available at https://coralreefwatch.noaa.gov/product/50km/. Supplemental_Information: All products mentioned in this metadata file are accessible at https://coralreefwatch.noaa.gov/product/50km/.

The twice-weekly global 50km satellite SST, used for deriving the SST Anomaly and coral bleaching heat stress monitoring products (Coral Bleaching HotSpot, Degree Heating Week, and Bleaching Alert Area), was a satellite-based nighttime ocean temperature analysis. The SST for earlier years (before February 1, 2016) was derived from measurements by the Advanced Very High Resolution Radiometer (AVHRR) sensors onboard NOAA's Polar-orbiting Operational Environmental Satellites (POES). Each twice-weekly SST analysis was based on data from one AVHRR sensor onboard a single POES. As of February 1, 2016, however, the twice-weekly 50km SST analysis was based on NOAA's operational daily global 5km Geostationary-Polar-orbiting (Geo-Polar) Blended Nighttime-only SST Analysis. Note: the accuracy of the twice-weekly global 50km satellite coral Bleaching Alert Area product depends on the accuracy of CRW's twice-weekly global 50km satellite coral bleaching Degree Heating Week and Coral Bleaching HotSpot products, which, in turn, depend on the accuracy of the twice-weekly global 50km satellite SSTs and bleaching threshold SSTs. Evaluations of the performance of the twice-weekly global 50km satellite products throughout the years have shown that these products demonstrate remarkable success in detecting, monitoring, and predicting all large spatial scale mass coral bleaching events. Polar Orbiting Environmental Satellite (POES) AVHRR-SST values used for creating CRW 50km SST analysis fields were accurate to within 0.5 degree Celsius and adjusted by in-situ buoy observations to best approximate SST at the depth of one-meter. However, when producing a complete, gap-filled SST analysis with global coverage, estimation of SST at the pixels covered by cloud may occasionally reduce the accuracy of SST at these pixels.

Process_Step: Process_Description: The level of coral bleaching heat stress at a data grid presented in the Bleaching Alert Area product is determined by the values of Degree Heating Week and Coral Bleaching HotSpot at the data grid. A Degree Heating Week is calculated as the accumulation of Coral Bleaching HotSpots over 12 consecutive weeks. At each satellite pixel, a coral bleaching threshold SST value is subtracted from the SST value to produce a Coral Bleaching HotSpot. See the CRW web site at https://coralreefwatch.noaa.gov/product/50km/ for more information.
