  1. David Parker, T. H. Achtor, L. E. Gumley University of Wisconsin – Madison (SSEC/CIMSS) CIMSS Student Workshop Madison, WI 23 June 2014 Weather Satellite Data for Mobile Devices

  2. Mobile Devices are the Future “The mobile device will be the primary connection tool to the Internet for most people in the world in 2020” (Pew Research Center, 2008) But… What will they look like? Funny image courtesy of R. Dengel

  3. Two Mobile Apps • SatCam • Satellite coordinated sky observations • WxSat • Satellite imagery display

  4. SatCam • Coordinate sky (cloud) observations with polar orbiting satellite overpasses • AQUA, TERRA, Suomi-NPP • SatCam notifies you of upcoming passes based on your current location • Differentiates between night and daytime passes

  5. SatCam • Uses built-in iOS Notification Center as well as custom voice cues • Ten minute warning • Ten second countdown • Notifications can be disabled • Completely • By time of day

  6. SatCam • Provides simple guided steps to recording sky and ground observations • Record sky picture • Categorize sky type • Record ground picture • Categorize ground type • Submit for processing

  7. SatCam • Sky image capture • At closest approach • When pointed skyward • Sky classifications • Clear, Mostly Clear, Mostly Cloudy, Overcast • Ground classifications • Urban, Green Veg., Brown Veg., Snow, Desert, Water

  8. SatCam • Review your observations • Organized into categories • Unsubmitted • Not uploaded for processing • Submitted • Received but not processed • Processed • Satellite view is available • Available in 30-120 minutes

  9. SatCam • Examine observations in detail • Date/time of observation • Date/time of satellite pass • Sky and ground conditions • Zoom in on images • Captured sky and ground observations • Satellite view of your location

  10. SatCam • Great for outreach • Intuitive connection • See what tax dollars support • Collecting valuable data for calibration and validation • Cloud mask products • Cloud/ice differentiation • Looking to the future… • Website, gamification

  11. SatCam • Available on the App Store for FREE since July 2012 • Over 12,000 submissions from all around the world

  12. WxSat • Simple way for anyone to explore global composite imagery • Grew from Russ Dengel’s “PAW” website • Leverages SSEC WMS

  13. WxSat • Clean interface with clear options • Visible • Infrared • Water Vapor • Toggle map overlay • Animation and time controls • Select animation time frame • Select specific day/time

  14. WxSat • Interface rotation

  15. WxSat • iPad optimized

  16. WxSat • iPad optimized

  17. WxSat • Animation and time settings • 2 Hours • 30 minute intervals • 6 Hours • 1 hour intervals • 12 Hours • 2 hour intervals • 24 Hours • 4 hour intervals

  18. WxSat • Time can be displayed in local (am/pm) or UTC format

  19. WxSat • Specific images within the selected time frame can be viewed

  20. WxSat • Free pan/zoom • Display current location • Built on top of iOS MapKit APIs • Google Maps in iOS 4/5 • Apple Maps in iOS 6+ • Simple political map overlay that can be toggled on/off

  21. WxSat • Animation • UI disappears • Time and progress indicator

  22. WxSat • 1km VIS • All global composites are created hourly • WxSat automatically looks for new imagery every 15 minutes

  23. WxSat • Global composites of Visible, Infrared and Water Vapor • Full native resolution • ~4km IR/WV global • ~1km VIS global • Products are all produced at SSEC

  24. WxSat • SSEC WMS backend • Web Map Service • Very flexible product cataloging and serving • Infrastructure for ingest and maintenance • Over 250 products currently • This App is one of many ways to view the imagery

  25. Summary • SatCam • Available for iOS • WxSat • Available for iOS and Android

  26. Summary “The mobile device IS the primary connection tool to the Internet for most people in the world” (D. Parker)
