Real-Time Winds Aloft

Current measurements of winds in the lower atmosphere, which help determine the movement of air pollution across Texas.

The TCEQ operates a network of three radar wind profilers. Wind measurements from these profilers are used to determine the transport of air pollution and to help validate model-generated wind fields used for air quality modeling.

TCEQ Data

How It Works

The radar profilers transmit radio wave pulses into the atmosphere and then record the resulting backscattered radio waves to measure winds in the range from 137 meters (449 feet) to 3,601 meters (11,814 feet) above ground level.

Real-time wind data plots are generated every 30 minutes from the radar profilers and relayed to this Web site for display. The plots show the last 12 hours of wind profiles. The wind data are plotted in standard meteorological form, with a vector line indicating the wind direction and barbs indicating the wind speed. The barbs are plotted on the tail of the wind vector (the end where the wind is coming from). Each full barb indicates five meters per second of wind speed (about 10 knots or 12 miles per hour) and a half-barb indicates 2.5 meters per second (about five knots or six miles per hour). The wind plots are colorized for wind speed using the color scale shown on the right side of the plot.

National Oceanic and Atmospheric Administration (NOAA) Data

Data from the TCEQ radar profilers are available from NOAA Forecast Systems Laboratory at Multi-Agency Profiler Graphical Data DisplaysExit the TNRCC.
