Additional Satellite Datasets
Additional Satellite Datasets
Posted January 12, 2015Voyager’s “remote sensing” > “satellite data” category now contains a few additional datasets. Voyager continues to provide daily, weekly, and monthly Advanced Very High Resolution Radiometer (AVHRR) global sea surface temperature (SST) at a spatial resolution of 0.1 degrees (approximately 8 km per pixel). We now also provide the higher resolution Global 1-km Sea Surface Temperature (G1SST) daily composite produced by NASA Jet Propulsion Laboratory (JPL). Spanning June 2010 up to the present, this blended product optimally interpolates SST observations from multiple satellite instruments and in situ observations, including the following:
- Advanced Along Track Scanning Radiometer (AATSR)
- Advanced Microwave Scanning Radiometer-EOS (AMSR-E)
- Advanced Very High Resolution Radiometer (AVHRR)
- Geostationary Operational Environmental Satellite (GOES) Imager
- Moderate Resolution Imaging Spectroradiometer (MODIS)
- Multi-Functional Transport Satellite 1R (MTSAT-1R) Radiometer
- Spinning Enhanced Visible and Infrared Imager (SEVIRI)
- Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI)
- in situ data from drifting and moored buoys

We also now provide additional biology-related satellite data derived from the Moderate-Resolution Imaging Spectroradiometer (MODIS). In addition to MODIS estimates of chlorophyll-a concentration that Voyager already provides, the system now distributes daily, weekly, and monthly composites of chromophoric (or colored) dissolved organic matter (CDOM), particulate organic carbon (POC), and particulate inorganic carbon (PIC) for the time period spanning 2003 up to the present. Produced by the Ocean Biology Processing Group (OBPG) at NASA Goddard Space Flight Center (GSFC), these products help scientists gain a better understanding of phytoplankton and their impact on the Earth system through the oceanic carbon cycle.

These new Voyager data offerings are hosted by the NOAA OceanWatch West Coast regional node at the Pacific Fisheries Environmental Laboratory (PFEL) in Pacific Grove, California, who gather the data from their respective providers and re-serve them via THREDDS Data Server (TDS) and ERDDAP. These servers enable standardized, interoperable, remote access mechanisms like Web Map Service (WMS) and OPeNDAP that Voyager leverages to incorporate, visualize, and redestribute these data to our users.
