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. |
