NASA distributes Diffuse Attenuation Coefficient at 490 nm Wavelength data from NASA's Aqua satellite. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft.

This Coastal Relief Gridded database provides the first comprehensive view of the US Coastal Zone; one that extends from the coastal state boundaries to as far offshore as the NOS hydrographic data will support a continuous view of the seafloor. In many cases, this seaward limit reaches out to, and in places even beyond the continental slope. The gridded database contains data for the entire coastal zone of the conterminous US, including Hawaii and Puerto Rico.

NOAA CoastWatch provides SST data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft.

MODIS measures chlorophyll fluorescence, which gives insight into the physiology of phytoplankton in the ocean. When phytoplankton are under stress, the rate at which the fluoresce can be decoupled from the rate of photosynthetic productivity.

NOAA CoastWatch distributes science quality wind stress data in zonal, meridional, modulus, and wind stress curl sets. This data begins with wind velocity measurements from the SeaWinds instrument onboard NASA's QuikSCAT satellite. SeaWinds is a microwave scatterometer designed to measure surface winds over the global ocean. NOAA CoastWatch processes wind velocity to wind stress and wind stress curl.

MODIS measures photosynthetically available radiation that may be used to mode primary productivity. THIS IS AN EXPERIMENTAL PRODUCT: intended strictly for scientific evaluation by professional marine scientists.

NOAA CoastWatch distributes chlorophyll-a concentration data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. The algorithm currently used in processing the water leaving radiance to chlorophyll concentration has not yet been accepted as science quality. In addition, assumptions are made in the atmospheric correction in order to provide the data in a timely manner.

NOAA CoastWatch distributes chlorophyll-a concentration data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) on the Orbview-2 satellite. Because the data was purchased under a NOAA contract with GeoEye, the data can be used but not redistributed. Images made from the data, however, can be used for any purpose. Questions regarding data access should be directed to NOAA CoastWatch.

NOAA CoastWatch provides SST data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. Currently, only daytime imagery is supported. This is Science Quality data.
