  Description: 
    Abstract: This file contains NOAA Coral Reef Watch (CRW)'s most recent 
      Operational global satellite nighttime AVHRR sea surface temperature (SST) anomaly 
      raw data at 50km resolution produced twice-weekly in near-real-time.
      The SST anomaly is the difference of SST compared to daily SST climatology.
      Satellite data from the Advanced Very High Resolution Radiometer (AVHRR) on
      NOAA's Polar Orbiting Environmental Satellite (POES) are used to generate
      AVHRR-SST. The most recent AVHRR data obtained from the POES that is presently
      in operational mode are processed to generate the near-real-time SSTs and SST 
      anomalies. This data file is in Hierarchical Data Format Release 4 (HDF4) that is 
      a commonly used data format. The SST data and SST anomaly data
      are produced twice-weekly on every Tuesday (using AVHRR data from the previous
      Saturday through Monday) and on every Saturday (using AVHRR data from the
      previous Tuesday through Friday).
    Purpose: The twice-weekly near-real-time global 50km satellite nighttime SST anomaly 
      data were primarily developed for NOAA's Coral Reef Watch (CRW) for both 
      monitoring and assessment of coral bleaching. CRW's other satellite coral bleaching
      monitoring and assessment products include SST, coral bleaching HotSpots,
      Degree Heating Weeks, Tropical Coral Bleaching Indices, SST time series, etc.
      SST Anomalies also show upwelling "scars/wakes" from tropical storm
      activity and regions where excess "fuel" is available for tropical storm
      intensification and quickly point out anomalous large-scale climate swings
      such as El Nino and La Nina.
    Supplemental_Information: The SST anomaly chart created from this SST anomaly data 
      is accessible at http://www.osdpd.noaa.gov/PSB/EPS/SST/climo.html
      The graphic display of the SST data used to derive the SST anomalies is available at
      http://coralreefwatch.noaa.gov/satellite/current/key_sst_50km_field.html

  Attribute_Accuracy: 
    Attribute_Accuracy_Report: Polar Orbiting Environmental Satellite (POES) 
      AVHRR-SST values are accurate to within 0.5 degrees C and adjusted by 
      in-situ information (buoys) to best-approximate SST at a depth of 1 
      meter. However, to provide a complete global coverage, estimation of 
      SSTs at all pixels that are cloud covered may occasionally reduce the 
      accuracy of SST at these pixels. The accuracy of the SST anomaly 
      depends on both SST and the SST climatology. No estimation on the 
      accuracy of the SST anomaly has been done yet.
  Logical_Consistency_Report: none
  Completeness_Report: None for the SST anomaly. The information for the AVHRR-
    derived sea surface temperature is described in the following user's guide.

      Process_Description: At each pixel, climatological sea surface temperature value 
        is subtracted from AVHRR sea surface temperature value to produce sea surface
        temperature anomaly. The global SST anomalies are then stored in HDF format.
