Title: Utility of JPSS Products for NWS forecasters.




The Joint Polar Satellite System (JPSS) will start a new series of polar-orbiting satellites that will assist with global atmospheric and environmental monitoring. The first satellite to launch from this series is JPSS-1, which will launch in early spring 2017. A prototype to the JPSS satellite series, the Suomi-National Polar-orbiting Partnership (Suomi-NPP) satellite was launched back in 2011, providing crucial data to weather agencies around the globe. On-board Suomi-NPP there are five instruments that provide the data: the Visible Infrared Imaging Radiometer Suite (VIIRS), the Advanced Technology Microwave Sounder (ATMS), Cross-track Infrared Sounder (CrIS), Ozone Mapping and Profiler Suite (OMPS) and the Clouds and Earth’s Radiant Energy System (CERES). An assortment of JPSS products have been produced by these instruments and a select few have been sent through the Satellite Broadcast Network (SBN) where products can then be viewable in the Advanced Weather Interactive Processing System-II (AWIPS-II); the forecasting and analysis software package for National Weather Service (NWS) forecasters. Currently, two JPSS products are in AWIPS-II, the Near-Constant Contrast (NCC) and the NOAA Unique Combined Atmospheric Processing System (NUCAPS). The NCC is a derived product of the Day/Night Band (DNB) that approximates the level of available moonlight and scales the imagery accordingly to provide optimal feature contrast for nighttime scenes. NUCAPS involves an ATMS and CrIS physical retrieval algorithm which produces vertical temperature and moisture soundings placed approximately ~ 50 kilometers apart from each other. The utility and the limitations of each of the products for NWS forecasters, plus supplemental information on other JPSS products will be highlighted in the presentation.
