Past observational studies have shown a decline in dust loading over the Indian landmass potentially caused by changing rainfall patterns over the desert regions. Such changes are expected to have a far-reaching impact on regional energy balance and monsoon rainfall. Using a regional climate-chemistry model, RegCM4.5, with an updated land module, we have simulated the long-term (2001\u20132015) changes in dust over the arid and semi-arid dust source regions of the North-Western part of the subcontinent. It is found that the area-averaged dust aerosol optical depth (AOD) over the arid and semi-arid desert regions has declined by 17% since the start of this millennium. The rainfall over these regions exhibits a positive trend of 0.1 mm day\u22121year\u22121 and a net increase of &gt;50%. The wet deposition is found to be dominant and ~five-fold larger in magnitude over dry deposition and exhibits total changes of ~79 and 48% in the trends in atmospheric dust. As a response, a significant difference in the surface (11%), top of the atmosphere radiative forcing (7%), and widespread atmospheric cooling are observed in the short wave domain of radiation spectrum over the Northern part of the Indian landmass. Such quantification and long-term change studies are necessary for understanding regional climate change and the water cycle.<\/jats:p>","DOI":"10.3390\/rs13214309","type":"journal-article","created":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T23:54:33Z","timestamp":1635292473000},"page":"4309","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Assessment of Recent Changes in Dust over South Asia Using RegCM4 Regional Climate Model"],"prefix":"10.3390","volume":"13","author":[{"given":"Acharya","family":"Asutosh","sequence":"first","affiliation":[{"name":"Indian Institute of Technology Bhubaneswar, Bhubaneswar 752050, Odisha, India"}]},{"given":"S.K","family":"Pandey","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Bhubaneswar, Bhubaneswar 752050, Odisha, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8573-6073","authenticated-orcid":false,"given":"V","family":"Vinoj","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Bhubaneswar, Bhubaneswar 752050, Odisha, India"}]},{"given":"Ramakrishna","family":"Ramisetty","sequence":"additional","affiliation":[{"name":"TSI Instruments India Private Limited, Bangalore 560102, Karnataka, India"}]},{"given":"Nishant","family":"Mittal","sequence":"additional","affiliation":[{"name":"TSI Instruments India Private Limited, Bangalore 560102, Karnataka, India"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18707","DOI":"10.1029\/95JD02051","article-title":"Contribution to the atmospheric mineral aerosol load from land surface modification","volume":"100","author":"Tegen","year":"1995","journal-title":"J.
