Kite Anemometers

Kite anemometry is the use of a kite as a sensor to measure the wind velocity, vector and turbulence. It is differentiated from other methods of kite meteorological data gathering in that information is obtained by observing the kite and the forces acting on it. This typically means that all substantial instrumentation is on the ground versus being flown on the kite as a payload.

In different configurations a kite anemometer can be used to examine wind speed at altitude, turbulence, and wind shear. The math behind a kite anemometer-- equations relating the pull of a kite to wind speed-- can also be used to determine the payload capacity of a kite in a specific wind speed.

You can contribute to this project by:

Forking the TALA repository and improving the design documentation, assembly instructions, or to add hardware or software for acquiring and interpreting data.


In the late 70's a number of patents were made regarding a system in which a series of kites were to be used to monitor conditions near airports. This system became known as the Tethered Aerodynamic Lifting Anemometer (TALA) patented under US Patents 3,767,145, 4,058,010, 4,152,933 & 4,221,351. Inspired by this device, further research into it and the general concept of kite anemometry was conducted throughout the 1980's and early 1990's. No other commercial kite anemometers other than the TALA were produced.

Wind direction & turbulence visualization:


Another method to utilize the Tethered Aerodynamic Lifting Anemometer kite is to purchase some surveyors tape (preferably a high visibility color for the given sky condition). A 10 m length of surveyors tape will stay within one or 2° of horizontal once the wind is over 2 m/s. You can attach the length of surveyors tape several meters below the kite and then again at five or 10 m below your first (or more) streamer/s if you wish to monitor multiple altitudes. The streamers can be attached a variety of ways but it is recommended (unless you are using Kevlar line) to put a knot at the end of the streamer and "larkshead-ing" a small closed loop of string at the interval you wish to measure before you fly. Once the kite is aloft all that needs to be done is larkshead the streamer knot onto the already placed closed loop. The following video gives an overview of how to add items to the flight line but since TALA can be flown in high winds it would be advisable to use the methods in the video prior to flight.

All that is left is to fly the kite with the streamers attached and then photographically record the streamer/s in-flight. This will yield instantaneous results of wind vectors at one or more altitudes and by monitoring the behavior of the streamer it is possible to analyze turbulence. A rolling or curling of the streamer will indicate turbulence.

While the manual on the original system does not mention this, it is safe to assume that multiple lengths of 10 m x 1" wide streamers would generate a significant amount of drag and make wind velocity measurements utilizing the spring scale inaccurate. This is apparently meant as a separate activity from anemometry. Data analysis is simple because it is photographic and should you also have a video camera or video mode on your particular camera you can monitor the wind turbulence and vector over time. The directions of the streamers can be compared with compass readings made while flying the kite and that is pretty much all there is to it.
