Abstract : This study investigates the co-variation in retrieved cloud and aerosol parameters using CERES observations to evaluate the effect of aerosol on atmospheric processes, its dynamics-thermodynamics as well as its radiative forcing. Co-variation statistical analysis with meteorological parameters associated, is studied for 4 years from 2014 to 2017 over Delhi for 3 seasons separately. In recent times, there is a significant rise in the pollution level over Delhi which is the motivation behind this piece of work to find some inference of the effect of aerosol in perturbing the regional climatic conditions. This study reveals that the possible effect of aerosols on regional cloud physical processes is significant and seasonal differences are unique. The evolution of cloud properties that includes cloud liquid and ice water paths, cloud particle effective radii, cloud base pressure and temperature are compared with that of aerosol concentration. Results suggest that there lies a strong correlation between cloud droplet growth and cloud water paths and aerosols concentration. A correlation of the cloud-top temperature and the base pressure with the aerosol concentration is also consistent. The statistical results presented here, are quite substantial to conclude the influence of aerosol on the cloud.
