Cloud, Aerosols and Ice Measurements in the Saharan Air Layer

The CALIMA campaign was carried out at the Izaña Observatory, Tenerife, in August 2013. The objective of CALIMA was to study the ability of Saharan dust particles to act as nuclei for ice and cloud droplets. The number and type of aerosol particles on which cloud droplets and ice crystals form influence the microphysical and radiative properties of clouds. We operated the ALABAMA mass spectrometer to measure chemical composition, size distribution and mixing state of single particles. Unfortunately, several technical problems occured, such that the ALABAMA did not collect a sufficient amount of data.
