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.

The attributes in this dataset are believed to be accurate.
Maximum scale of intended use is 1:80,000.
Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness.
These data are believed to be logically consistent. Geometry is topologically clean.

Monthly or Annual Climatologies for Chlorophyll-a Concentration
1
(1) Monthly and annual climatologies for chlorophyll-a concentration were downloaded using the Marine Geospatial Ecology Toolbox. The tool used to download these data is 'Create Climatological Rasters for NASA OceanColor L3 SMI Product'. The climatologies are created using monthly resolution data at a 10-year temporal resolution from 2007 to 2016. (2) Data were projected from WGS 1984 GCS to WGS 1984 World Mercator (WKID: 3395).
