TL;DR: The CLARA project as mentioned in this paper has several sub-projects and related projects, and the main purpose is to understand and model the radiative transport in a cloudy atmosphere, information on the cloud structure, optical properties and microphysics is indispensable.
Abstract: To understand and model the radiative transport in a cloudy atmosphere, information on the cloud structure, optical properties and microphysics is indispensable. In order to obtain a complete data set, four national institutes joined their efforts in the CLARA project. After the start of the preparations for the first campaign, the total number of participating national and international institutes increased to ten. In total three experimental campaigns took place in the Netherlands in 1996. An extensive set of instrumentation was employed during the experimental campaigns including lidars, radar, infrared radiometers, microwave radiometer and radiosondes. Furthermore, insitu aircraft measurements were carried out. With an FSSP the cloud droplet size distribution and the liquid water content was measured. The CLARA project has several sub-projects and related projects. It is not the scope of this paper to cover all the aspects. In this paper a short description of the CLARA-

TL;DR: In 1996, intensive measurements campaigns were organized in The Netherlands with a multitude of instruments, aimed at a qualitative and quantitative description of clouds and their impact on atmospheric radiation as mentioned in this paper, which was part of the Clouds and Radiation (CLARA) project.
Abstract: In 1996, intensive measurements campaigns were organized in The Netherlands with a multitude of instruments, aimed at a qualitative and quantitative description of clouds and their impact on atmospheric radiation. The campaigns were part of the Clouds and Radiation (CLARA) project: an intensive experimental study of clouds and radiation in The Netherlands. Originally, three specific objectives were defined:
