NOAA Coral Reef Watch Operational Near-real-time Twice-weekly Global 50 km Satellite Coral Bleaching Thermal Stress Monitoring Product Suite from 2009-12-31 to 2010-12-30 (NODC Accession 0075824)

NOAA's polar-orbiting satellites measure SST around the globe in near-real-time, and Coral Reef Watch produces a suite of products derived from this set of satellite SST and uses them to pinpoint areas around the world where corals are at risk for bleaching. This is a suite of operational products produced at 0.5 degree (approximately 50 km) spatial resolution twice-weekly. The products include nighttime sea surface temperature, nighttime sea surface temperature anomaly, coral bleaching HotSpots, and Degree Heating Weeks for the global oceans.美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的极轨卫星可近乎实时地在全球范围内采集海表温度（Sea Surface Temperature, SST）数据。珊瑚礁观察（Coral Reef Watch）项目依托这套卫星海表温度数据集研发了一系列产品，并利用这些产品精准定位全球范围内珊瑚面临白化风险的海域。该系列业务化产品的空间分辨率为0.5度（约50公里），更新频次为每周两次，产品涵盖全球海域的夜间海表温度、夜间海表温度距平、珊瑚白化热应激热点（HotSpots）以及累计加热周数（Degree Heating Weeks）。
