Previously, chlorophyll from the NASA OC3 NIR algorithm regionally tuned for Chesapeake Bay (Werdell, 2007) had been available. This is now available only by request. More information

The Daily Map Viewer (at top of page) diplays MODIS chlorophyll generated from both of the above algorithms:

1. Regionally tuned NASA OC3 NIR algorithm: 30 January 2009 - 1 October 2014
2. NOAA OC3 NIR-SWIR algorithm: 1 October 2014 - present

Total suspended matter (TSM) is a measure of the concentration of material in the surface water including mud, silt, and other fine-scale debris. More information

Effect of 2011 tropical storm Lee on Chesapeake Bay

Diffuse Attenuation Coefficient at 490 nm (Kd-490) from MODIS measures how strongly light intensity at the specified wavelength (490 nm) is attenuated within the water column. This Kd-490 product is specific for Chesapeake Bay with higher accuracy for Chesapeake Bay than the standard "KD2" product.
