Short summary
We present the first long-term MAX-DOAS measurements of aerosols, nitrogen dioxide and formaldehyde tropospheric columns, vertical distributions, and temporal variation from Mohali in the Indo-Gangetic Plain. We investigate the effect of various emission sources and meteorological conditions on the measured pollutants and how they control ozone formation. These measurements are also used to validate the corresponding satellite observations and are also compared against in situ observations.
