Abstract: A high-frequency Doppler sodar for precipitation measurements has been developed. Such a Doppler sodar (6?20 kHz) can almost always measure precipitation and turbulence spectra simultaneously. Therefore, the mean vertical ...

Abstract: A common feature of all capacitance humidity sensors is their undesirable hysteresis effect due to the unequal adsorption and desorption of water vapor on the surfaces of their dielectric porous materials. To eliminate ...
