This page has been superceded by the Data Portal Viewer. Please use the updated and improved tool which allows multiple layers data. The NOAA CoastWatch granule selector enables a user to select a Level-1 or Level-2 dataset by selecting a date and clicking on the granule that covers the user's area of interest. For VIIRS near real-time data is available for the last 15 days and science quality data is available from 2012 up to near real-time coverage. Clicking a granule will open an information window containing a link to the preview image and/or data file. If multiple files are desired (each file can be 18 to 550 MB), clicking on the download icon (Download Icon) will add the selected granule to a list that can be downloaded and used to retrieve files using local software.
