20221206 13493700 1.0 TRUE Total Suspended Matter Four raster layers show the seasonal (Spring, Summer Fall and Winter) concentration of Total Suspended Matter (or Total Suspended Solids) in milligrams per liter (mg/L) in surface water (approximately top 1 meter of surface water). Dataset was acquired from NOAA Coast Watch East Coast Node (http://eastcoast.coastwatch.noaa.gov/). The dataset represents 7-year seasonal average (2009-2015). Once-daily satellite overpasses for years 2009-2015 are averaged for spring, summer, fall and winter seasons. Spring: Mar., Apr., May; Summer: Jun, Jul., Aug.; Fall: Sep., Oct., Nov.; Winter: Dec.., Jan, Feb. Spatial Resolution: 250 meter satellite nadir resolution gridded to 70 meter grid.
