Atmospheric turbulent fluctuations interfere wave propagation in the atmosphere. Therefore they are important to know to describe the atmospheric influence on imaging, laser propagation and electro-optical sensor performance. Regarding in situ point measurements standard instrumentation for monitoring turbulent fluctuations are ultrasonic anemometers. These instruments have a good accuracy in high frequency single temperature and wind speed measurements, but they are very expensive. Often they serve as a reference for a whole measurement area. To characterize a complex or heterogeneous area better, cheaper and yet still reliable all-you-can-measure weather measurement systems would help to increase the amount of measurement stations and gathered data. These would allow a better understanding and description of local environmental conditions and serve for a better validation of high resolution models. We set up a low-budget three-dimensional instrument also on the base of monitoring the velocity of sound in the atmosphere. The new instrument is to be developed, assembled and tested. A 3D printed housing will be used for saving the sensor of environmental conditions. First steps of the development of the new instrument will be presented and discussed.
