        Water Temperature

          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

          Chlorophyll-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:

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

          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

          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
