Meskhidze’s research interests include laboratory and ambient measurements of sea spray aerosol hygroscopicity and cloud condensation nuclei (CCN) properties and application of remotely sensed data (MODIS, MISR, CALIPSO) for exploring potential interactions between marine aerosols, ocean productivity, clouds, and climate. His research group is also working on the development of parameterizations of organic aerosol and trace gas emissions from the oceans required for regional and global climate models.
