Chesapeake and Delaware Bays Satellite Data
Data Descriptions and Download Links
AVHRRSurface 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).
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.
MODISChlorophyll-a from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the NASA Aqua satellite, processed using the NOAA OC3 algorithm with the combined NIR-SWIR atmospheric correction (NOAA OC3 NIR-SWIR). 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:
Total Suspended Matter from MODIS
Total suspended matter (TSM) is a measure of the concentration of material
in the surface water including mud, silt, and other fine-scale debris.

Diffuse Attenuation Coefficient at 490 nm
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.
A high-resolution Kd-490 at 250m spatial resolution is also available from MODIS. The algorithm was developed by NOAA National Ocean Service, and is well-suited for coastal and turbid water.
True Color satellite image data from the Visible Infrared Imaging Radiometer Suite (VIIRS) at 750 m spatial resolution. Data files contain red, green and blue radiance data; images are also available. More information
