Assessing the aerosol and moisture transport to the Arctic through atmospheric river and their impact on clouds

The transport of aerosols to the Arctic plays a key role in shaping local climate processes, particularly in the context of Arctic amplification. Here, we utilize an atmospheric river detection algorithm to identify and analyze extreme aerosol and moisture transport events from mid-latitudes to the Arctic over a 43 year period.By examining the combined effects of aerosol and moisture intrusions, we aim to understand how the presence of aerosols alter the cloud properties compared to scenarios with only moisture. Inorder to evaluate the cloud properties, we use the active remote sensing product DARDAR-Nice dataset.

The findings will provide insights into aerosol-cloud interactions in the Arctic, offering a better understanding of the role of aerosol transport in Arctic climate change and thereby improving the accuracy of climate model projections.
