20221206 13493700 1.0 TRUE Concentration of Total Suspended Matter (Spring, 2009-2015)(mg/L) This raster image shows the concentration of Total Suspended Matter (or Total Suspended Solids) in milligrams per liter (mg/L) for spring surface water (approximately top 1 meter of surface water). The dataset represents 7-year seasonal average (2009-2015). Once-daily satellite overpasses for years 2009-2015 are averaged for spring (March, April and May). Spatial Resolution is 250-meter satellite nadir resolution gridded to 70-meter grid. NOAA CoastWatch East Coast Node (http://eastcoast.coastwatch.noaa.gov/)
