My hope is that in the future, modelers can use detailed information on INP sources from studies like mine to better constrain Arctic cloud formation in models of all scales by having the necessary source information. This was one topic that came up in the community discussion during my CATCH seminar that I think is crucial. To reduce the uncertainties of quantifying cloud impacts on the surface energy budget, we have to take a step back to the basics and understand how they form and evaluate the role of aerosols in the formation process.
