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 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.

Analyzed Foundation, Microwave + InfraRed Optimally Interpolated, Science Quality, Global, Sea Surface Temperature data. The through-cloud capabilities of microwave radiometers provide a valuable picture of global sea surface temperature (SST). To utilize this, scientists at Remote Sensing Systems have calculated a daily, Optimally Interpolated (OI) SST product at quarter degree (~25 kilometer) resolution. This product is ideal for research activities in which a complete, daily SST map is more desirable than one with missing data due to orbital gaps or environmental conditions precluding SST retrieval. Improved global daily NRT SSTs should be useful for a wide range of scientific and operational activities. The addition of SST derived from Infrared (IR) measurements allows higher spatial resolution, and SST near land. However, IR input is less accurate than MW due to cloud contamination. Blending MW and IR enables greater coverage and higher accuracy than IR only SSTs, but current OI does not completely eliminate cloud contamination inherent to IR SSTs.

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 CoastWatch distributes chlorophyll-a concentration data from NASA's Terra 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 Oregon State University (OSU) College of Oceanic and Atmospheric Sciences (COAS). THIS IS AN EXPERIMENTAL PRODUCT: intended strictly for scientific evaluation by professional marine scientists.

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.
