ITWS Description 

— from the FAA ITWS site 

What Is ITWS?
The Integrated Terminal Weather System (ITWS) is an automated weather information system, and it uses a variety of weather sensors to make full use of airport runways in all kinds of weather.

What Does ITWS Do?
The ITWS receives data from weather and surveillance radars and sensors, and then uses computer software to display current weather information in graphic and text formats. The ITWS provides weather products that are easy to understand and it removes the need for interpretation by meteorologists.

What Weather Information Does ITWS Use?
The ITWS receives data from FAA and National Weather Service (NWS) sensors as well as airborne aircraft flying within a few miles of airports. The ITWS uses weather products such as the Terminal Doppler Weather Radar, Next Generation Weather Radar, and Airport Surveillance Radar-Model 9. Other inputs are received from the National Lightning Detection Network, NWS Rapid Update Cycle data, and the Meteorological Data Collection and Reporting System. The ITWS also uses the Low Level Wind Shear Alert System and Automated Weather Observing System and Automated Surface Observing System.

What Weather Information Does ITWS Generate?
ITWS detects and predicts wind shear, microbursts and gust fronts and it displays current precipitation levels. The system tracks the speed and direction of storm cells, and predicts the movement of storms. It also detects hail, lightning, and tornadoes.
