Introducing NexSat

• NexSat is a public web site depicting near real
  time satellite value-added imagery products over
  the continental United States. Supported by IPO.
  
• NexSat demonstrates VIIRS using the current suite
  of RD and operational sensors NASA-MODIS,
  DMSP-OLS, and NOAA-AVHRR, supplemented by GOES.
• Utilizes additional polar microwave data
  WindSat, CloudSat, SSM/I, AMSU-B, etc.
• Additional data from U.S. Navys numerical
  weather prediction models (NOGAPS and COAMPS).

The Role of NexSat

• Current Scope
• Educational, but used by some operations
• Targeting the broadest audience (not just the
  experts)
• Simple and visually intuitive examples.
• Beyond NexSats Current Scope
• A formal operational resource (24/7 support)

• Under adequate lunar illumination conditions, the
  VIIRS DNB will provide quantitative information
  on cloud reflectance, allowing for markedly
  improved cloud characterization beyond IR-only
  approaches.

CONUS Dust Storms
While far less frequent than the Middle East, the
deserts of the southwestern U.S. produce an
occasional noteworthy dust storm. Above,
multispectral MODIS enhances a storm near Fallon
AFB.

City Zooms
NexSat high spatial resolution (250 m pixels)
true color zooms over major U.S. cities provide
users with an NPOESS-quality snap shot of weather
conditions over their own backyard twice per
day.

• I feel this is a critical effort and we should
  partner and move out on showing the citizens of
  the US the benefits of this data
  -Dave Jones, CEO StormCenter Communications
• Please keep us in tune with the current tech.
  The stratus at SFO is a high visibility FAA
  problem with the potential of saving millions
  just by being able to forecast the clearing of
  stratus and cancellation of a Ground Delay by 0.5
