Fig. 1: Correlation between GRs observed from the evolution of the particle size distribution and calculated from simultaneously measured concentrations of OOMs using NO3- CIMS.

The assumed contribution from sulfuric acid has been subtracted from the observed GR (GR-GR(H2SO4)). a The results for the 1.5–3 nm size range and b The 3–7 nm size range. Data from three measurement sites is shown: Hyytiälä, Finland (squares); Beijing, China (diamonds) and San Pietro di Capofiume, Italy (triangles). The color code represents the temperature. The circles show results from the CERN CLOUD experiment from pure α-pinene ozonolysis experiments at three different temperatures (−25 °C, +5 °C, +25 °C). The dashed line shows the expected GR for the case that all OOMs measured by the NO3− CIMS would condense at a rate limited only by the collision kinetics (kinetic limit).
