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.

Currents, HF Radar, Monterey, Near-Real Time, Hourly, 2.0 km

Surface ocean velocities estimated from HF-Radar are
representative of the upper 0.3 - 2.5 meters of the
ocean.  The main objective of near-real time
processing is to produce the best product from
available data at the time of processing.  Radial
velocity measurements are obtained from individual
radar sites through the U.S. HF-Radar Network.
Hourly radial data are processed by unweighted
least-squares on a 2 km resolution grid of the U.S.

NOAA CoastWatch distributes near real time Ekman current (in zonal, meridional, and modulus sets) and Ekman upwelling data.  This data begins with wind velocity measurements from the ASCAT instrument onboard EUMETSAT's ASCAT satellite.  ASCAT 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, and finally to Ekman current and Ekman upwelling.

NOAA CoastWatch, Sea Surface Height Anomalies from Altimetry, Global, 2017-present, EXPERIMENTAL

The altimetry data are from RADS (http://rads.tudelft.nl/rads/rads.shtml), the Radar Altimetry Database System, first developed at Delft University of Technology, now also at the NOAA and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The RADS data for each mission is updated with state of the art corrections for tides, atmospheric path delay, etc. Because they are all computed consistently between the various missions, this avoids the possibility of introducing biases and drifts because of the different implementation of the various corrections by different agencies. The goals of RADS are to provide a homogenous dataset of sea level anomalies, wave heights, and wind speeds, along with database selection and analysis tools.
