Improving Information Presentation to Aviation
Users

Aviation Grids – new efforts
Gridded TAF verification How good are the
grids?

An aviation weather revolution!

The days of text-only forecasting are over!
+
Aviation forecast products need to be:• Graphical or text/graphic hybrid• Areal as well as point-based• Highly detailed in space and time• Frequently updated• Human parsable
New Products
April 15, 2010ER Subregional Aviation Conference
Recent National Examples
LAMP/CCFP hybridNational cig/vis grids from NCARLAMP probability graphicsGraphical AIRMETs
RLX Efforts
Probability of Thunder (PoT) GridsTerminal Status BoardKML (Google Earth) Displays
Probability of Thunder Grids (PoT)• Generated every hour out to 7 days
• Used to create Wx grids, and therefore incorporated into public forecast products and TAFs
• Can be generated either manually by forecaster or via smart tools that use model parameters (CAPE, LI, K) or ensemble data (SREF)
RLX Graphical Forecasts
April 15, 2010ER Subregional Aviation Conference
Probability of Thunder Grids (PoT)• Has been (and will be) used in aviation-specific data displays
• In combination with enhanced short term forecasting philosophy, allows for a frequently updated, detailed areal convective forecast
RLX Graphical Forecasts
April 15, 2010ER Subregional Aviation Conference
Terminal Status Board Quick overview of problematic parameters at chosen airports
Configurable by user for as many or as few terminals as desired
Detailed parameters can be accessed via either mouse float or mouse click
Useful for situational awareness and decision making processes
Aviation Test Bed

Terminal Status Board• Four columns: current, 0-3 hour forecast, 3-6 hour forecast, 6+ hour forecast
• Colors: green (VFR), yellow (MVFR), red (IFR), purple (LIFR) – can be configured for other parameters and for airport-specific thresholds

Aviation KML Displays• Example of using man/machine mix to present information in a concise display for CWSUs
• Present data from TAFs, NDFD, LAMP, and RUC13 to aid in decision making
• Uses KML files which can be displayed by several programs, including Google Earth

April 15, 2010ER Subregional Aviation Conference
Aviation KML Displays• Box/triangle represents forecast trend of PoT
• Inner triangle – 0 to 3 hr fcst, outer box – 3-6 hr fcst, both color coded
• Triangle points down/up (worse/better conditions) for increasing/decreasing PoT
