Aerosols are, therefore, important players in determining the properties and lifetimes of cloud properties, and the aerosol-cloud interactions have a significant role in the Earth\u2019s climate system. The size and composition of an aerosol particle affects its ability to act as cloud condensation nuclei. There are still unknowns in the composition dependence of the cloud droplet forming ability, especially for the organic aerosols. Our laboratory facilities and instrumentation allows as to study water uptake of model aerosol systems. The unique measurement station at the top of the Puijo-tower, which is maintained in collaboration with the Finnish Meteorological Institute, facilitates in-cloud measurements of aerosol properties and cloud droplet activation. Our group\u2019s research objects related to aerosol-cloud interactions are:<\/p>\n<ul>\n<li>hygroscopicity of aerosol particles under sub- and super-saturation<\/li>\n<li>cloud droplet activation<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Relating articles<\/h3>\n<ul>\n<li><span id=\"yui_patched_v3_11_0_1_1503492133132_553\" class=\"pb_toc_link\">Romakkaniemi, S., Maalick, Z., Hellsten, A., Ruuskanen, A., V\u00e4is\u00e4nen, O., Ahmad, I., Tonttila, J., Mikkonen, S., Komppula, M., and K\u00fchn, T.
