## AWRP Goals

- Outcomes
- Reduce Weather-Related Accidents & Incidents
- Relieve Weather Impact on System Capacity & Efficiency
- Outputs
- Provide Capability via Applied Research to Generate Weather Observations, Warnings, and Forecasts with Higher Resolution & Accuracy
- Improve Accessibility & Delivery of Weather Information

- FAA AWRP, AUA-430

**Notes:**
Increased safety, capacity & aircraft utilization due to enhanced forecasts of inflight icing including severity

Enhanced strategic and traffic flow management planning due to storm cell growth & decay predictions

Increased safety & capacity due to enhanced detection, forecast of turbulence including clear-air

Increased capacity due to short-term forecasts of ceiling & visibility in the terminal area

Increased safety and capacity due to enhance definition of the location, timing, and severity of convective wx hazards

Savings in the use of deicing fluids, increased safety (departures) and capacity and efficiency in runway/airport plowing

Improved access and delivery of wx information due to ADDS

**Notes:**
Since the name of this panel is “Opportunities for Implementation,” I wanted to show you that we do have a plan.  You’ll be happy to hear that I’m not going to walk you through this.
I will draw your attention to the Keystone shape in the middle toward the right.  That keystone box represents the Aviation Weather Center, and in particular, the Aviation Digital Data Service, or ADDS, that we have established there.  For many of our products, the AWC is the key to our implementation, especially through the Aviation Digital Data Service (ADDS), which is in public use now.

## Aviation Digital Data Service (ADDS)(AGFS PDT)

- Web-based delivery mechanism
- Located at and operated by the NWS Aviation Weather Center
- Includes flight path vertical cross section data
- Rave reviews by users
**GA pilots**: “Great site.  Easy to use and navigate.  Tax dollars for something really worthwhile.  Keep up the good work.”  “One of the best programmed, most smartly laid out, sights I have seen in a long time.  The information is easily accessible and extremely useful.  An unprecedented source of powerful, easily accessed weather information now in the hands of people who can benefit from it.”
**FedEx pilot**: “...this is the best aviation weather site I have access to.  I especially like the flight planner mode.  I have notified all my friends and have taken the liberty to load this site on the computers at  work.”
**Airline Dispatcher**: “Ya'll must be in the genius category !! We use ADDS at work along with other cool stuff on the internet to back up our own system.  the flight path tool is awesome ! I mean awesome...I can really use this kind of data on an hourly basis.  Keep up the good work...._are you sure ya'll work for the government ? Not what you'd expect from Uncle Sam_....if you know what I mean.  Fantastic !!

## Terminal Convective WeatherForecast Product

***Terminal Convective Weather******Forecast Product***

**DFW Traffic Manager:**
**“****We love this thing”**

**Land additional aircraft (that would have diverted) **** **
**Have arrivals ready when weather clears**

- FAA AWRP, AUA-430

**Notes:**
The FAA is currently testing an advanced convective weather forecast product at Dallas-Ft. Worth and Orlando that provides a time animation of the past changes in storm locations and then shows forecast positions out to 60 minutes in the future.  The performance of the product depends on the weather of the day with the best performance occurring for organized weather systems such as squall lines.  The prediction algorithm provides a running score of its performance on a given day  for the case illustrates, the 30 minute forecast has been producing a critical success index of 70% while the 60 minute forecast has a critical success index of 50%.  The controllers have been told us scores in excess of 50% are very helpful operationally whereas scores of about 20% are much less useful. (See http//www.ll.mit.edu/AviationWeather/tcwfp.html).

## National Convective Weather Forecast

- FAA AWRP, AUA-430

**Notes:**
Two different thunderstorm products have been undergoing field tests.  The terminal convective wx product in the upper left shows one frame of a loop of images, from 60 minutes in the past to 60 minutes in the future in 10-minute time steps.  It has been turned on & will be assessed by the William J. Hughes Technical Center this year at the Memphis ITWS site in preparation for adding it into ITWS.

The National Convective Wx Product in the lower right is aimed more at en route users.  Several regional airlines have used it with great success.  It is available in an experimental status on the NWS ADDS web page now, and later this year, it will be released for operational use there and over the AOC-Net.

## Integrated Turbulence Forecasting Algorithm (ITFA)

## WSDDM Implemented AtAll 3 New York Airports

- FAA AWRP, AUA-430

**Notes:**
This system has been technology transferred to ARINC who has implemented it operationally (Port Authority of NY & NJ is the customer) at the 3 NY Airports (JFK, LaGuardia, Newark) and has provided valuable winter wx information to the users this winter.
