Polar-orbiting multi-band meteorological sensors such as the Suomi National Polar-orbiting Partnership (SNPP) VIIRS imager pose substantial challenges for creating high quality imagery for use by environmental forecasters, scientific analysis environments, and the general public. To do this quickly and easily, the JPSS project has funded the Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin to create an open-source, modular application system, Polar2Grid. This bundled solution automates tools for converting satellite data such as VIIRS into a variety of output formats, including GeoTIFFs, AWIPS compatible NetCDF files, and NinJo forecasting workstation compatible TIFF images. In addition to traditional visible and infrared imagery, Polar2Grid includes three perceptual enhancements for the VIIRS Day-Night Band (DNB), as well as providing the capability to create sharpened true color, sharpened false color, and user-defined RGB images. Polar2Grid performs conversions and projections in seconds on large swaths of data. Polar2Grid is currently providing VIIRS imagery over the Continental United States, as well as Alaska and Hawaii, from various Direct-Broadcast antennas to operational forecasters at the NOAA National Weather Service (NWS) offices in their AWIPS terminals, within minutes of an overpass of the Suomi NPP satellite. Three years after Polar2Grid development started, the Polar2Grid team is now releasing version 2.0 of the software; supporting more sensors, generating more products, and providing all of its features in an easy to use command line interface.This presentation will includes examples of how the end products of Polar2Grid are being used by the NWS, as well as the global direct broadcast community.
