There are complex interactions between different sources of aerosols, particularly in mountainous regions. And also, how these aerosols can influence atmospheric processes like precipitation, glacier melting, and more, are intriguing. The combined effects of aerosols from local and long-range sources have a stronger impact than individual sources, particularly when secondary aerosols are considered. Secondary aerosols are playing substantial role on elevation dependent climate change in the Western Himalayas. The aim of this study is to dynamically monitor the behavior of secondary aerosol spatially and temporally over the region of our concern. Also, considering the influence of secondary aerosols specifically towards the elevation dependent warming trend in relation to their abundance and source characteristics, this study aims to refine the local characteristics of secondary aerosol through thorough study of dynamics of local microclimates.
