Abstract

During the Intensive Field Operation (IFO) of the International Cirrus Experiment 1989 (ICE’89), four ground-based lidar systems were operated in a mesoscale network (cf. Fig. 1) in the German Bight to investigate geometrical and optical properties of cirrus cloud fields. The arrangement in an array with distances of roughly 75 km between the stations allowed the discrimination between local features and more general properties of cirrus. The lidar systems were technically quite different and in particular used different wavelengths, as they had been designed for different purposes long before ICE. The key features of each system are summarized in Table 1 together with the quantities that could be measured during the ICE’89 campaign.
