NOAA CoastWatch distributes chlorophyll-a concentration data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. THIS IS AN EXPERIMENTAL PRODUCT: intended strictly for scientific evaluation by professional marine scientists. The algorithm currently used in processing the water leaving radiance to chlorophyll concentration has not yet been accepted as science quality. In addition, assumptions are made in the atmospheric correction in order to provide the data in a timely manner. The units of the data are mg Chl-a m^-3.
Products are intended for federal, state, and local government environmental decision makers. Other uses include recreational boating, educators, resource managers, and researchers. Products are validated with in situ measurements to quantify their accuracy.
For further information on the data set, including a description of processing steps, calibration and validation methods, and references, see the Pre-Dissemination Review. These documents will be available on the website in the future. Users should note that data marked as clouds could be either clouds or missing data.

Files are available in ASCII, NetCDF, HDF, MATLAB, GIF, or PDF formats.
Compressed files are compressed using ZIP method.
All data is accessible through the CoastWatch, West Coast Regional Node website: https://coastwatch.pfel.noaa.gov. Primary access to the data is through the CoastWatch Browser. The CoastWatch Browser is a web page for selecting, viewing, and downloading near-real-time satellite data and other data for the west coast of the U.S. and Mexico. It creates custom maps on-the-fly of the data that you select. The maps can include bathymetry contour lines, contour lines from other data sets, and vectors from other data sets. The data can be downloaded in several different data file formats.

The ASCII format is recognized by most GIS software and common commercial spreadsheets. The GIF format is recognized by most graphics applications. The PDF format is a file format designed for electronic document display, and can be viewed using PDF viewing software. The HDF format is recognized by image analysis programs including CDAT, a freely distributed viewing program provided by NOAA CoastWatch. The MATLAB format is recognized by MathWorks MATLAB computing software.
