Examination of aerosol indirect effects during cirrus cloud evolution

Abstract: Abstract. Aerosols affect cirrus formation and evolution, yet quantification of these effects remain difficult based on in situ observations due to the complexity of nucleation mechanisms and large variabilities in ice microphysical properties. This work employed a method to distinguish five evolution phases of cirrus clouds based on in situ aircraft-based observations from seven U.S. National Science Foundation (NSF) and five NASA flight campaigns. Both homogeneous and heterogeneous nucleation were captured i… Show more

“…These environments were underrepresented in the training dataset [20]. Measurement of W in these conditions also carries a larger experimental error (∼ 0.3 m s −1 ) [24]. Nevertheless, Figure 2 shows that the B24 model performs well across diverse environments and can generalize beyond its training data.…”

“…The in-cloud RHi dominates the deposition/sublimation process of ICs and plays an important role in cloud evolution [15][16][17]. At present, the understanding of cirrus evolution is still incomplete, and there are very few studies that have investigated the mechanisms related to the wide range of in-cloud RHi [18][19][20][21][22][23][24].…”
