Vertical ozone profiles taken with four collocated differential-absorption lidar systems were compared with in-situ measurements from a UV absorption and a chemiluminescence ozone analyzer on board an airplane and a tether balloon. Spatial overlap between the airplane and the balloon data, although limited by the minimum flight height required for the airplane and the ceiling of the balloon, showed that ozone in the lower troposphere exhibits considerable natural variation. Lidar data agree well with the in-situ data if the lidars are operated in compliance with the recommendations by the Commission of Air Pollution Prevention (KRdL) of VDI and DIN. On average there seems to be, though, a small negative bias that has so far not been explained. Best results are obtained if, by an experienced operator or via a special algorithm, data are cut out that are contaminated by large backscatter gradients at the edges of patches of fog or clouds.
