Assessment :: Nighttime Microphysics and DNB Imagery: Fog vs Low Clouds at High Latitudes

(September – October 2013 for northwest CONUS, December 2013 to February 2014 for Alaska)
This report describes the 2013/14 assessment of multi-spectral, false color composites produced by the NASA Short-term Prediction Research and Transition (SPoRT) Center, similar to other products developed previously by the Naval Research Laboratory (NRL) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT). The assessment was conducted with users at high latitudes (N. CONUS, and Alaska) and sought to determine the value added to the short-term forecast of ceiling and visibility, particularly as they apply to TAFs issued by high-latitude WFOs. In addition, the assessment exposed forecasters to the application of complex multi-spectral imagery (i.e. RGB composite), and hence, the future paradigm of satellite imagery that will become available in the JPSS and GOES-R eras.

Full title: VIIRS and MODIS Multi-Spectral Imagery Assessment for Aviation Weather and Cloud Analysis at High Latitude – Winter 2013-14

Product(s): Nighttime Microphysics RGB, VIIRS Day Night Band, SPoRT 11-3.9 micron difference hybrid imagery

Date: September – October 2013 for northwest CONUS, December 2013 to February 2014 for Alaska

Region: Northwest CONUS, Alaska

Need(s) Addressed: Analysis of  clouds to support short-term aviation forecasts.  Particularly, to assess value of products to differentiate fog from low clouds
