Summary
Abstract: ABSTRACT: NOAA CoastWatch produces near real-time ocean color products, e.g. chlorophyll-a concentration and turbidity (reflectance), with data from NASA's GeoEye's Orbview-2 satellite (via contractual purchase). The data is collected by selected HRPT ground stations. Each level 2 satellite specific product has unique characteristics dependent on the sensor and the algorithm applied. While level 2 ...

Purpose: PURPOSE: The purpose of SeaWiFS data is to examine oceanic factors that affect global change and to assess the oceans' role in the global carbon cycle, as well as other biogeochemical cycles, through a comprehensive research program. SeaWiFS data are being used to help clarify the magnitude and variability of chlorophyll and primary production by marine phytoplankton and to determine the distribution and timing of spring blooms, i.e., the time of highly abundant growth.

Quality ATTRIBUTE ACCURACY REPORT: Ocean Color values are accurate to within 10 percent. NOAA CoastWatch performs validation of the data through buoy match-ups or other in situ measurements for adjusting processing algorithms as necessary. Chlorophyll values (.001 - 64.767 micrograms per liter) in GeoTIFFs are scaled to 1 to 100. The current turbidity product is the remote sensing reflectance for band 5 ... View entire text
Access Constraints ACCESS CONSTRAINTS: If you need access to the data (i.e., HDF files) or near real-time SeaWiFS imagery (i.e., coastal management, resource monitoring) then you must become a registered user, due to licensing contracts with OrbImage. Users may find instructions on how to become registered users with SeaWIFS at http://coastwatch.noaa.gov/cw_faq.html#ocean%20color.
