Integrated Aviation Weather Solution (IAWS)

The Integrated Aviation Weather System, or IAWS, is an innovative aviation weather observation and forecasting solution for airports. The system enables en route hazard warnings to be issued to help ensure pilots and air traffic control officials have the crucial information they need about severe weather to make essential air traffic management and airport operations decisions.

Innovative Features

Tailored for terminal and regional aviation weather, IAWS’s high spatial-temporal resolution, integrated observation, and robust model system forecasting will enhance the safety of air traffic management and airport operations.

With accurate and timely aviation weather information that supplies frequent updates, IAWS enhances forecasting productivity and quality, and assists with critical operation decision making to improve aviation safety and fuel economy.
