the relatively coarse spatio-temporal resolution of the satellite retrievals prevented the Potential NPF maps from capturing short-lived or local NPF events, - no single site could be considered representative of the Arctic as a whole, - several challenges have limited the strength of the conclusions, - the study is still not the final word in the Pan-Arctic narrative of aerosol-cloud interactions

The precipitation over the Arctic region is a difficult quantity to determine with high accuracy, as the in situ observation network is sparse, and current climate models, atmospheric reanalyses, and direct satellite-based precipitation observations suffer from diverse difficulties that hinder the correct assessment of precipitation.
