abstract: NOAA Coral Reef Watch program produces a suite of near-real-time global 50 km monitoring products, based on sea surface temperature (SST) observations from NOAA's Polar-orbiting Operational Environmental Satellites (POES), to pinpoint areas around the world where heat stress is sufficient to cause mass coral bleaching. This product suite is produced twice a week operationally and includes nighttime sea surface temperature, nighttime sea surface temperature anomaly, coral bleaching HotSpot, Degree Heating Week, and Bleaching Alert Area products.
purpose: This dataset is available to the public for a wide variety of uses including scientific research and analysis.

supplementalInformation: Coral Reef Watch's (CRW) near-real-time twice-weekly global 50 km (0.5 degrees exactly) satellite coral bleaching thermal stress monitoring products are CRW's heritage operational products and form the core of CRW's first Decision Support System for tropical coral reef management. The products include Sea Surface Temperature (SST), SST Anomaly, Coral Bleaching HotSpot, Degree Heating Week (DHW), and Bleaching Alert Area products. These products are based on NOAA/NESDIS' operational twice-weekly global 50 km nighttime SST Analysis derived from the Advanced Very High Resolution Radiometers (AVHRR) onboard NOAA's Polar-orbiting Operational Environmental Satellites (POES). A set of SST climatologies and coral bleaching SST threshold climatology are used to derive SST anomaly, HotSpot, DHW, and Bleaching Alert Area from SST Analysis. All products are currently updated twice-weekly every Monday morning (using observations from the previous Thursday through Sunday) and Thursday morning (using observations from the previous Monday through Wednesday), U.S. Eastern Time. Prior to May 3, 2007, the products were updated every Tuesday morning (using observations from the previous Saturday through Monday) and Saturday morning (using observations from the previous Tuesday through Friday), U.S. Eastern Time. The data are available for use without restriction, but it is required to credit NOAA Coral Reef Watch program for any data use. Recommendations for citing and providing credit are provided at http://coralreefwatch.noaa.gov/satellite/docs/recommendations_crw_citation.php. Users are referred to the footer section of Coral Reef Watch's website (http://coralreefwatch.noaa.gov/) for disclaimers, policies, notices pertaining to the use of the data. Data layers included in the data files: Data Layer; Definition; Type; Dimensions (RxC) CRW_SST; Twice-weekly global 50km satellite nighttime sea surface temperature; int16; 331x720 CRW_SSTANOMALY; Twice-weekly global 50km satellite nighttime sea surface temperature anomaly; int16; 331x720 CRW_HOTSPOT; Twice-weekly global 50km satellite coral bleaching HotSpot; int16; 331x720 CRW_DHW; Twice-weekly global 50km satellite coral bleaching Degree Heating Week; int16; 331x720 CRW_BAA; Twice-weekly global 50km satellite Bleaching Alert Area; int16; 331x720 surface_flag; Pixel characteristics flag array; uint8; 331x720 Individual SST, and SST Anomaly, HotSpot, DHW, and BAA HDF files contain two data layers including the corresponding data layer named in the table above (CRW_SST, CRW_SSTANOMALY, CRW_HOTSPOT, CRW_DHW, and CRW_BAA) and a surface_flag layer. Each of these files also contains an 8-bit raster image of the corresponding geophysical data layer contained in the file. The dimension of each image is 720 columns by 411 rows. Each image displays a data layer in its pre-defined color scale and the color legend is shown on each image. Corresponding color palette is attached on each image and extractable from the HDF file. An all-in-one file is also available and contains all the data layers, except for the CRW_BAA data layer, listed in the table and their raster images with color palettes. All these data files are in HDF format, containing internally all the necessary information to understand and to properly use the data. Liu, G., J.L. Rauenzahn, S.F. Heron, C.M. Eakin, W.J.

code: AVHRR-2
type: AVHRR-2
description: Advanced Very High Resolution Radiometer-2 The AVHRR-2 is a multi purpose imaging instrument used for global measurement of cloud cover, sea surface temperature, ice, snow and vegetation cover and characteristics. This instrument was initially carried on NOAA-7 (launched June 1981) and was last flown on NOAA-14 which was decommissioned in 2005. This 5-channel radiometer covering 2 visible and 3 thermal infrared between 0.63 and 12.0 micrometers, has an instantaneous footprint of 1.1 km at the sub satellite point.

code: AVHRR-3
type: AVHRR-3
description: Advanced Very High Resolution Radiometer-3 The AVHRR-3 is a six channel scanning radiometer providing 3 solar channels in the visible-near infrared region and 3 thermal infrared channels. The AVHRR-3 has two one-micrometer wide channels between 10.3 and 12.5 micrometers. This latest version of AVHRR was first carried on NOAA-15 launched in May 1998 and subsequently in all current NOAA and MetOp platforms. Measuring the same view, this array of diverse wavelengths, after processing, permits multi spectral analysis for more precisely defining hydrologic, oceanographic, and meteorological parameters. Comparison of data from two channels is often used to observe features or measure various environmental parameters. The three channels operating entirely within the infrared band are used to detect the heat radiation from and hence, the temperature of land, water, sea surfaces, and the clouds above them.
