Based on both static (extended Köhler) and dynamic modelling, we investigate the influence of temperature, humidity, HNO3 initial concentration, as well as of the particle concentration, on the efficiency of HNO3-mediated laser-induced condensation. This mechanism is most efficient for low temperatures, high HNO3 concentration, and relative humidities. It is, however, still active up to 30 °C, down to 70% relative humidity, and below the ppm level of HNO3. Furthermore, lower particle concentration minimizing the depletion of both HNO3 and water vapor is more favourable to particle growth.
