CRW Next-Generation 5-km Composite Product Suite


* For details on HDF data format, please read the description on our HDF data web page. The free CoastWatch Data Analysis Tool to view these HDF data files and perform data analyses can be downloaded from that page. Note: the file size can be up to ~500KB for a single variable HDF data file, ~3MB for an all-in-one annual HDF data file, and ~2MB for an all-in-one monthly data file.
** An all-in-one HDF data file contains all of the available composites for the selected timeframe.


The images and data posted on this web page are composites of NOAA Coral Reef Watch's operational twice-weekly global 50-km satellite coral bleaching monitoring products. A monthly composite is derived from the corresponding data from all the twice-weekly periods that end in that month. An annual composite is derived from the corresponding data from all the twice-weekly periods that end in that year. Current year-to-date composites are derived from the corresponding data from all the twice-weekly periods starting from the beginning of the year to the past month in which all twice-weekly data are available. They are updated each month when the monthly composites are produced.

To learn more about the related operational twice-weekly 50-km products, please go to the corresponding product pages (available via coralreefwatch.noaa.gov/satellite/index_50.php); check out our detailed product methodology web page; or view our recent NOAA/NESDIS Technical Report about the product suite.
