NOAA Coral Reef Watch program 20000101 One Remote sensing image, animation, HDF data, ASCII, KML, Google Earth, webpage Silver Spring, Maryland, USA NOAA Coral Reef Watch program http://coralreefwatch.noaa.gov/satellite/current/products_hotspot.html The NOAA Coral Reef Watch (CRW) satellite Coral Bleaching HotSpots product is part of the CRW operational near-real-time global 50-km satellite coral bleaching thermal stress monitoring product suite. This product suite was initially implemented in 2000 and continues to provide updated monitoring information twice-weekly. This metadata file provides information on the HotSpots product for both the most recent near-real-time updates and the archived HotSpots product dating back to 2000. A Coral Bleaching HotSpot is a specific type of sea surface temperature (SST) anomaly that measures the amount of SST exceeding a static coral bleaching threshold SST; it serves as a measure of instantaneous bleaching thermal stress and shows the occurrence, magnitude, and spatial distribution of the stress during the twice-weekly period ending on the day indicated in the product. All non-positive HotSpot values are recorded as zeros. A more detailed description of the HotSpots product can be obtained at: http://coralreefwatch.noaa.gov/satellite/methodology/methodology.html#hotspot. Near-real-time satellite data from the Advanced Very High Resolution Radiometer (AVHRR) on some of NOAA's Polar Orbiting Environmental Satellites (POES) were used to generate AVHRR-SST that this CRW product suite is based on. Related details, as well as other important information, are provided in each HotSpot HDF data file. Additionally, CRW's coral bleaching Degree Heating Weeks Product (another key tool in the CRW operational product suite) is derived from the accumulation of the HotSpots. The HotSpots product is available in various formats, including static image, animation, HDF data, and Google Earth and is delivered through multiple mechanisms, including websites, ftp, and OPeNDAP, along with time series data in text format at selected locations, known as CRW Satellite Virtual Stations. The product, its detailed description, and available data formats and delivery mechanisms are accessible at: http://coralreefwatch.noaa.gov/satellite, along with general CRW product information and access to other CRW products. The NOAA Coral Reef Watch program seeks to fully utilize space-based sea surface temperature (SST) observations combined with in-situ data to continually monitor for early indications of thermally-induced coral reef bleaching worldwide. A suite of monitoring and predicting products, including this satellite HotSpots product, has been developed by CRW as a decision support system to provide critical and timely coral reef environment information to the U.S. and international coral reef communities.

Silver Spring Maryland 20910-3226 USA 301-713-2857 ext 109 301-713-3136 coralreefwatch@noaa.gov http://www.ospo.noaa.gov/data/cb/hotspots/hotspotgcurrent.gif This is the most recent image of the NOAA CRW operational near-real-time twice-weekly global 50-km satellite Coral Bleaching HotSpots product. GIF The accuracy of the HotSpots product depends on the accuracy of satellite SSTs, and bleaching threshold SSTs. A full evaluation and validation of CRWs HotSpots have not been completed yet. A preliminary evaluation revealed, however, that the HotSpots product, along with coral bleaching Degree Heating Weeks product (another key tool in the CRW operational product suite), demonstrates 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 50-km 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. none There is no spatial data gap existing in this data set. No change will be made to the original HotSpots data, but occasional revisions to some images may occur if an inaccuracy is detected in the image display of the data. New near-real-time HotSpots products will be continuously added into this data collection at scheduled routine data update times.
