This is regarding the Level-2 Processing Land Flag that is used to mask the water pixels very close to the coastline to avoid the impact of adjacent land reflectance. Is there a standard "buffer" size considered to mask these pixels ? For a 1 km product how many pixels adjacent to the coast are masked? Is it the same for Chl a, TSS and SST? Also are these flags site specific? My study areas are the Galveston Bay(Texas), Mobile Bay (Alabama) and the Caloosahatchee Estuary (Florida). In order to use 1 km, 500 m and 250 m products, how many pixels near the coast need to be masked to avoid the impact of land reflectance? Can anyone please suggest some literature that discusses this issue?
