Value of Future GOES to USAF Operations John Zapotocny Chief Scientist, Air Force Weather Agency GOES-R User’s Conference - May 2004
Overview • AF Weather mission and customers • Imager interests • Space environment interests • Sounder interests • Specialized sensors • Satellite operations • Deployed vs. Central users
AFW Mission “Air Force Weather, as part of the Joint team, delivers accurate, relevant, and timely environmental information, products, and services, anywhere in the world. We directly impact decision superiority by enhancing predictive battlespace awareness and enabling commanders at all levels to anticipate and exploit the battlespace environment, from the mud to the sun.”
AFWA Backup for NOAA • Storm Prediction Center (NCEP/SPC) • Aviation Weather Center (NCEP/AWC) • Volcanic Ash Advisory Centers (VAAC) • Washington DC • Anchorage AK • NCEP regional modeling (NCEP/EMC) • Space Environment Center (SEC)
AFW Customers Air Force and Army Warfighters National Command Authorities Base/Post Weather Units Intelligence Community US Army US Navy US Air Force USPACOM USEUCOM USSPACECOM NORAD USSTRATCOM USTRANSCOM USSOCOM USCENTCOM USSOUTHCOM USARPAC USACOM USAFE USCINCPAC Coalition Allies

Advanced Baseline Imager (ABI) • AFW has similar interests and priorities as other users of new ABI capabilities • Aviation forecasting, severe weather, etc. • Detection of aerosols/thin cirrus/volcanic ash important to USAF operations
Gridded Analysis of total cloud amount ABI Interests • Automated cloud depiction (CDFS II) • Hourly analyses and forecasts of 3-D cloud layers worldwide from polar and geo satellite data • Additional channels and better resolution will improve detection and characterization • Fine-scale numerical modeling improved by direct radiance assimilation to specify cloud and moisture patterns
Low-light Imaging • AFW has long experience with low-light visible imaging on DMSP • DMSP provides visible cloud images into twilight and with lunar illumination (>25%) • Low-light imaging on GOES can • Extend useful visible data by 2-3 hours/day • If sensitive enough nighttime fires or other anomalous lights can be detected (aurora, etc)

Space Environment Solar Corona Solar Wind Magnetosphere Ionosphere Ultimately depends on what’s happening on the Sun
Solar X-Ray Imager Interests • AF Weather has mission to provide space weather analyses, forecasts, and warnings to DoD operators and decision makers • Continued reliance on X-ray and energetic particle sensors for real-time warnings • Solar X-Ray Imager (SXI) improves AFW capabilities for monitoring and forecasting solar events
Advanced Baseline Sounder (ABS) • ABS will provide RAOB-quality soundings with very high temporal and spatial resolution • Direct radiance assimilation into NWP models will be in wide use by GOES-R+ era • Ensemble methods Targeted observation processing • Better for training missions in US, operations over Western Hemisphere, Homeland Security, backup for NWS centers
Special Events Imager (SEI) • High-resolution (300m) multi-spectral depiction of short-term events • Volcanic plumes, dust, fog, floods, clouds, etc. • Reasonably short reaction time (notification to first data) important • Offers details and temporal coverage not available from other satellites
Volcanic Ash Plume Analysis Volcanic Ash Cloud Kyushu Sakura-jima Volcano DMSP F12 Fine Imagery
Lightning Mapper • AFW interested in intra/inter-cloud (IC) lightning for flight safety • Thunderstorm forecasts required for areas outside of current detection equipment • Most systems only detect cloud-to-ground (CG) strikes in/near CONUS • Need IC lightning detection, OCONUS coverage
Scan Strategy Impact • AF Weather often forecasts for regions with limited conventional data and relies heavily on satellite obs • Reduced scanning of South America has negative impacts on forecasting ability • US Southern Command users can’t receive data for their areas of responsibility • Southern Hemisphere cloud analyses and forecasts have reduced input data • Full-disk every 15 min meets MJCS 154-86 DoD requirements
Strategic Center Users • Require best data available • High-rate Imagery Transmission (HRIT) or GVAR equivalent • More flexible on antenna size and complexity

Deployed Users • Lightweight, portable, rugged equipment for remotely deployed units lacking reach-back connectivity • Receive antenna should not require tracking and be easily aligned • Low-rate Imagery Transmission (LRIT) likely to be signal of choice • Data will also be available via network reach-back (JMIST concept) • Key downlink nodes with HRIT ingest/processing capability stage data for network access

Summary • Air Force Weather requirements similar to NOAA/NWS and NOAA/SEC for GOES data • Continued importance of direct readout capability by lightweight ground systems but future emphasis on network reach-back to key downlink nodes • New terrestrial and space environment sensors (LM, SXI, SEI) will have significant operational benefits within USAF
