Paper Abstract

A cw CO2 Doppler lidar was modified for an airborne test of the principles of the true-airspeed sensor. During two flights in April 2000 the system was tested together with the wind sensor in the noise-boom of the research aircraft. The results are (i) there is an excellent correlation between the LOS components of the Doppler lidar and of the aircraft sensor; (ii) there is no dropout of dat also in very clean regions of the atmosphere; (iii) the Doppler sensor can also be used as an aerosol particle counter. A virtual instrument was used to design the sensor and was modified after the flight. It can be used to design a more compact fiber sensor.
