Chlorophyll-a

Metadata Updated: October 31, 2024

This algorithm returns the near-surface concentration of chlorophyll-a (chlor_a) in mg m-3, calculated using an empirical relationship derived from in situ measurements of chlor_a and remote sensing reflectances (Rrs) in the blue-to-green region of the visible spectrum. The implementation is contingent on the availability three or more sensor bands spanning the 440 - 670 nm spectral regime. The algorithm is applicable to all current ocean color sensors. The chlor_a product is included as part of the standard Level-2 OC product suite and the Level-3 CHL product suite. The data represents monthly mean climatologies on a monthly data time scale for a ten-year period between 2007 and 2016. These climatologies were created using the 'Create Climatological Rasters for NASA OceanColor L3 SMI Product' in the Marine Geospatial Ecology Toolbox for ArcGIS Desktop 10.1-10.6.
