The Bihar Pollution Pool as observed from MOPITT (version 4), CALIPSO (version 3) and tropospheric ozone residual data

Abstract

General Comments: This paper presents a multi-sensor assessment of tropospheric pollution over the Indo-Gangetic Plains (IGP) based on spaceborne observations of Carbon Monoxide, tropospheric ozone and aerosol loading. The IGP is a densely populated region fraught with high levels of anthropogenic pollution as well as is significantly influenced by seasonal biomass burning and dust storms that impacts the regional atmospheric chemistry and aerosol optical properties. The paper combines measurements from different satellite-based sensors and focuses on the heavy anthropogenic pollution over the eastern IGP during winter-time. The paper is generally well-written and the observations are portrayed in a clear and convincing manner. There are some revisions and comments that should be incorporated before the manuscript
