This data package includes 50 km monthly mean satellite-only nighttime SST climatologies for 12 months and the maximum of these monthly mean climatologies. The 12 monthly mean SST climatologies have been used for producing CRW near-real-time SST anomalies. The maximum climatology is also known as Maximum Monthly Mean SST (MMMSST) Climatology and has been used for producing CRW near-real-time HotSpots. For more information on these climatologies, please visit the methodology webpage.

Previous versions of the software tools

* The sea surface temperatures (SSTs) used in bleaching monitoring are nighttime-only and all other variables are derived from the nighttime-only SSTs.
** An all-in-one data file contains four variables (SST, SST anomaly, Bleaching HotSpot, and Degree Heating Weeks) and does not include Bleaching Alert Area product.
*** Unfortunately, our OPeNDAP service is temporarily not available.

A suite of datasets used by NOAA Coral Reef Watch for its near-real-time satellite coral bleaching monitoring are now available for download and use. These are the data that have been used for making the images and charts posted on our satellite monitoring website. The data are available in the Hierarchical Data Format (HDF) via FTP, HTTP, and OPeNDAP servers.

The first first three tables above list the available data files and the protocols in which the data can be downloaded. User can choose a desirable server for download by clicking on the server name. Using the OPeNDAP protocol, the metadata (i.e., the information about the data file) contained in an HDF data file can be viewed before download. Click here for more information about our HDF data.

The last table provides some software tools (the CoastWatch Software Library and Utilities) that can be used for visualizing data, viewing data information and values, calculating certain statistics, creating graphic output, etc. Please see our Software Details page for more information. The software is easy to install and use and is customized for Coral Reef Watch HDF data files. This software is not required to visualize and manipulate the data; many commonly used computer languages and software packages can read and process HDF files.
