AVHRR
Surface water temperature for Chesapeake Bay from NOAA's Advanced Very High Resolution Radiometer (AVHRR). Overpasses from all operating AVHRR instruments are averaged into a single daily, 3-day, or 7-day composite (composite includes day and night overpasses). Spatial resolution is 1km. More information

AVHRR-VIIRS Multisensor
Surface water temperature combined from the Advanced Very High Resolution Radiometer (AVHRR) and the Visible Infrared Imaging Radiometer Suite (VIIRS). Overpasses from all operating AVHRR and VIIRS instruments are averaged into a single daily composite (nighttime only). Spatial resolution is nominally 750 km.

PODAAC Multiscale Ultrahigh Resolution (MUR)
Surface water temperature analysis from all available infrared and microwave satellites. Coverage from all satellites and the analysis method assure cloud-free coverage on a daily basis. Product is "foundational" SST, i.e. surface temperature before the diurnal heating begins. Spatial resolution is 1 km. More information

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


OLCI
Chlorophyll-a from the Ocean and Land Colour Intrument (OLCI) onboard the European Sentinel-3A and 3B satellites, courtesy of the European Union's Copernicus satellite program. The data are processed with the European Space Agency's ocean color 4-band combination chlorophyll-a algorithm (OC4ME) and the MERIS 1999 Baseline Atmospheric Correction. More information

VIIRS
Chlorophyll-a from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi-NPP satellite, processed with the NOAA OC3 algorithm (Wang et al., 2017) and the NIR atmospheric correction of Jiang & Wang (2014). More information

Diffuse Attenuation Coefficient at 490 nm (Kd-490) measures how strongly light intensity at the specified wavelength (490 nm) is attenuated within the water column. It is a measure of the water's turbidity.
