Climatological trends in satellite-derived aerosol optical depth over North India and its relationship with crop residue burning: Rural-urban contrast

•Studied aerosol optical depth at urban and rural locations (2005–2018) in Indo-Gangetic Plains

•Observed positive trend of aerosol optical depth over both urban and rural areas

•Aerosol optical depth over a rural area is increasing at 0.50–0.67% per year.

•Crop residue burning increases aerosol optical depth during post-monsoon season.

•Established empirical relation between aerosol optical depth and PM10 for the region
