NOAA's nowCOAST® provides access to global weather satellite imagery
Previous extent of the geostationary satellite imagery (a.) compared to the new global mosaic of geostationary satellite imagery now available in nowCOAST (b.).

NOAA's nowCOAST®, a GIS-based online web mapping service that provides frequently updated weather and ocean observations, analyses, imagery, and ocean model forecast guidance, along with coastal and marine weather warnings and forecasts, now provides access to NOAA Satellite and Information Service’s global mosaic of geostationary satellite imagery (GMGSI).

The GMGSI includes visible, shortwave infrared, and longwave infrared imagery. The addition of the GMGSI will provide, for the first time on nowCOAST, weather satellite coverage for U.S. territories west of Hawaii. In addition, a mosaic of shortwave infrared imagery from GOES WEST and EAST will also now be available.  The shortwave infrared imagery provides additional cloud information as well as fog detection at night.  Similar to other map layers, the GMSGI can be overlaid on top of NOAA Raster or Electronic Navigational Charts on the nowCOAST’s map viewer.

GMGSI will be updated approximately every 3 hours in the nowCOAST map service and the mosaic of GOES West and East shortwave infrared imagery will be updated every 30 minutes to ensure the latest imagery are available to users as soon as it becomes available. The user can access this layer on the nowCOAST map viewer by going to “Observations/Remotely-Sensed/Weather Satellite Imagery.”

nowCOAST is an ArcGIS-based web mapping application developed by the Office of Coast Survey’s Coast Survey Development Laboratory and is hosted on NOAA’s 24 x7 high availability Integrated Dissemination Program IT infrastructure operated the NWS National Centers for Environmental Prediction.

The new satellite imagery is available on nowCOAST's map services via two protocols: GeoServices Representational State Transfer (REST) map services and Open Geospatial Consortium (OGC) compliant Web Map Services (WMS).  For additional information about the new satellite imagery visit: https://nowcoastqa.ncep.noaa.gov/arcgis/rest/services/nowcoast/sat_meteo_imagery_time/MapServer and http://www.ospo.noaa.gov/Products/imagery/.
