Summer Experiment 2018

The Aviation Weather Center will host the 2018 Aviation Weather Testbed Summer Experiment September 10-14, 2018. The experiment will focus on three main components: continued evaluation of high-resolution forecasts for SFO flight operations (including Met Office and HRRR model runs at sub 1-km grid spacing), evaluation of the expanded domain and improvements to the Graphical Forecasts for Aviation tool, and an evaluation of model guidance that can support enhanced Day 1-Day 4 planning guidance.

The experiment kickoff is Monday, September 10th at 7:30 am with coffee and introductions. Daily activities begin around 8:00 am and conclude between 4:00 and 4:30 pm depending on weather. Each day features a lunchtime seminar on varying topics.

Experiment Design

The 2018 AWT Summer Experiment will largely focus on the evaluation of experimental and prototype products and services to support aviation planning in the National Airspace System. This experiment will explore super high-resolution forecasts for short-term planning as well as new global forecasting models for longer-range planning.  More specific details and tasks will be presented at the time of experiment.  Below is an overview of what can be expected at each desk.

  • Continued Evaluation of Super High-Resolution Cloud and Visibility Products for SFO Flight Operations

    The Met Office will be providing near-real time 330-m resolution forecasts of aviation impact variables to support experimental clearing time forecasts for SFO.  In addition, GSD will be providing a nest of the HRRR model as another source of guidance for this domain.  GOES-17 and new versions of RTMA and RTMA-RU will be evaluated as high-resolution observation sets.

  • Evaluation of the experimental expanded Graphical Forecasts for Aviation (GFA) tool

    Currently, the Graphical Forecasts for Aviation with an expanded domain is available as an experimental product via This product will go through a more thorough evaluation process with AWT and FAA Aviation Weather Demonstration and Evaluation (AWDE) services personnel interacting with end-users during this week-long experiment.

  • Evaluation of guidance for enhanced Day 1 and extended Day 2-4 planning

    The AWC is currently discussing the potential to issue a produce similar to the SPC Day 1 product for severe thunderstorms but instead for severe low and high turbulence and significant mountain wave activity.  This involves the evaluation of high-resolution guidance for severe turbulence signals out to 36 hours in the future.  In addition, AWT participants will be asked to evaluation experimental FV3GFS guidance for the prediction of longer range impacts.
