NRL HYCOM 1/25 deg model output, Gulf of Mexico The HYCOM consortium is a multi-institutional effort sponsored by the National Ocean Partnership Program (NOPP), as part of the U. S. Global Ocean Data Assimilation Experiment (GODAE), to develop and evaluate a data-assimilative hybrid isopycnal-sigma-pressure (generalized) coordinate ocean model (called HYbrid Coordinate Ocean Model or HYCOM).

AVHRR Pathfinder Oceans Project seeks to create a long-term, continuous sea surface temperature data series for use in climate research. The Pathfinder SST data begins with historic AVHRR Global Area Coverage SST. This data is re-evaluated and re-calibrated, improving both the accuracy and number of valid SST values (due to improved cloud-masking).

MODIS data is used to develop an index of the amount of chromophoric dissolved organic material (CDOM) in the surface waters. CDOM absorbs heavily in the blue wavelengths and thus can skew many derived products, especially in coastal waters. THIS IS AN EXPERIMENTAL PRODUCT: intended strictly for scientific evaluation by professional marine scientists.

NOAA OceanWatch provides a blended sea surface temperature (SST) products derived from both microwave and infrared sensors carried on multiple platforms. The microwave instruments can measure ocean temperatures even in the presence of clouds, though the resolution is a bit coarse when considering features typical of the coastal environment. These are complemented by the relatively fine measurements of infrared sensors. The blended data are provided at moderate spatial resolution (0.1 degrees) for the Global Ocean. Measurements are gathered by Japan's Advanced Microwave Scanning Radiometer (AMSR-E) instrument, a passive radiance sensor carried aboard NASA's Aqua spacecraft, NOAA's Advanced Very High Resolution Radiometer, NOAA GOES Imager, and NASA's Moderate Resolution Imaging Spectrometer (MODIS). 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.

MODIS measures the remote sensing reflectance (Rrs) at 667nm. This can be used to view very high concentrations of phytoplankton in the very surface of the water.

NOAA OceanWatch provides sea surface temperature (SST) products derived from microwave sensors, which can measure ocean temperatures even in the presence of clouds. This data is provided at moderate spatial resolution (0.025 degrees) for the Global Ocean. Measurements are gathered by Japan's Advanced Microwave Scanning Radiometer (AMSR-E) instrument, a passive radiance sensor carried aboard NASA's Aqua spacecraft.

This data is re-evaluated and re-calibrated, improving both the accuracy and number of valid SST values (due to improved cloud-masking).

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.

OSU 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. Data is received from the satellite and processed to level 2 by the NASA GSFC Ocean Biology Products Group.
