With the remote airborne measurement of three dimensional wind field it is possible to observe a wide area in a relatively short period of time. On the other hand the knowledge of the exact velocity and orientation of the aircraft is mandatory. Any small deviation in these parameters will cause a systematic error in the estimated wind field. The conical scanning airborne cw carbon-dioxide Doppler lidar ADOLAR has been designed to gain experience concerning the correction of the inertial reference system on board the aircraft using the ground return as a reference and for testing different signal processing algorithms. Besides this the instrument can also be used for the measurement of small scale wind phenomena e.g. valley wind or flow around a hill. The lidar was used at two campaigns in 1994 and 1996 onboard the DLR research aircraft Falcon F20. The missions covered measurements overland where the ground return was used to calibrate several parameters of the lidar and the aircraft reference system as well as measurements over the North Sea and the Baltic Sea at regions with a lower aerosol density.
