TL;DR: It is found that pure biogenic nucleation and growth depends only weakly on temperature, and consistency between measured gas-phase product concentrations, product volatility, measured and modeled growth rates, and the particle composition over most temperatures found in the troposphere is established.
Journal ArticleDOI
Black carbon concentration and deposition estimations in Finland by the regional aerosol–climate model REMO-HAM

TL;DR: In this article, the prediction skill of the regional aerosol-climate model REMO-HAM was assessed against the black carbon (BC) concentration measurements from five locations in Finland, with focus on Hyytiala station for the year 2005.
Journal ArticleDOI
