  • DIGITAL AVIATION SERVICES COLLABORATIVE FORECAST PROCESS PHASE II

    In August 2017, the OPG partnered with the Aviation Weather Testbed (AWT) to conduct an evaluation of a proposed AWT-WFO Collaborative Forecast Process aimed at producing a single set of grids that meet the needs of aviation customers ranging from local TAF users to national air traffic management officials.

  • IMPACT OF COLOR VISION DEFICIENCY ON INTERPRETATION OF RGB COMPOSITES

    The successful launch of GOES-R in November 2016 initiated a new era for satellite meteorology. The availability of sixteen spectral bands, rendered at four times the resolution of current GOES imagery, and accessible by forecasters in near real-time, makes satellite imagery and products valuable for operational decision making in ways for which it was irrelevant in the past. In addition to identifying ways individual spectral bands can be used, considerable research has been devoted to creating composite imagery, comprised of combining multiple bands and/or band differences in the Red-Green-Blue (RGB) color space of AWIPS. These RGB composites are created to accentuate particular atmospheric features, thus assisting forecasters in the task of phenomena-based analysis. Early results in the U.S. reinforce successes documented by several years of operational RGB recipe use by meteorologists in western Europe. READ MORE...


  • NEAR STORM ENVIRONMENTAL AWARENESS EVALUATION

    In May and June of 2017, the OPG hosted Operational Readiness Evaluations for a collection of AWIPS-based tools designed to enhance a forecaster’s Near Storm Environmental Awareness (NSEA) during convective warning events. The NSEA toolset, comprised of a GUI application and a Cursor Readout, was developed as a collaborative National SOO Project to provide NWS mesoanalysts and warning forecasters with a flexible, locally configurable, and user-friendly way to monitor a variety of relevant parameters in rapidly evolving convective storm environments.

  • HIMAWARI-8 IMAGERY FLOWING TO THE OPG

    As part of the preparation for the 2016 launch of the GOES-R satellite, OPG will be conducting an evaluation of RGB products available on the Himawari-8 satellite, which has similar capabilities to what GOES-R will have. Sixteen spectral channels from Himawari-8 as well as several RGB products created by NASA SPoRT are now flowing to the OPG’s AWIPS-II workstation. OPG staff are now reviewing the Himawari imagery to identify possible case studies for the upcoming evaluation. READ MORE...


  • GOES-R 1-MINUTE IMAGERY EVALUATION

    In preparation for the launch of the Geostationary Operational Environmental Satellite (GOES)- R Series, the Operations Proving Ground (OPG) hosted six week-long evaluations of 1-minute satellite imagery in the first part of 2015. 17 National Weather Service (NWS) operational forecasters from four regions (Central, Southern, Western, and Eastern) completed eight simulations that were developed using imagery from the 2013 and 2014 GOES-14 Super Rapid Scan Operations for GOES-R (SRSOR) with the primary purpose of assessing the value and usefulness of integrating high temporal resolution satellite imagery into various analysis and forecast applications. Six additional forecasters participated in a follow-up assessment using live 2015 SRSOR imagery. READ MORE...


  • METEOGRAM TRACKING TOOL EVALUATION

    In May of 2014, NWS forecasters from all four CONUS Regions joined product developers, training officials, and OPG staff to conduct a rigorous evaluation of a potential tool for AWIPS-2. The tool is known as the Tracking Meteogram (TM) Tool, an application developed by NASA SPoRT in collaboration with the NWS Meteorological Development Lab. READ MORE...
