TY - T1 - Simple proxy for continental concentration of accumulation mode particles using reanalysis data SN - / UR - URN:NBN:fi:hulib-202108273577; http://hdl.handle.net/10138/333723 T3 - A1 - Ovaska, Aino A2 - PB - Helsingin yliopisto Y1 - 2021 LA - eng AB - Cloud condensation nuclei (CCN) participate in controlling the climate, and a better understading of their number concentrations is needed to constrain the current uncertainties in Earth’s energy budget. However, estimating the global CCN concentrations is difficult using only localised in-situ measurements. To overcome this, different proxies and parametrisations for CCN have been developed. In this thesis, accumulation mode particles were used as a substitute for CCN, and continental proxy for...
