Abstract: The two most serious dangers to nearly 60 percent of the world's population living in Asian monsoon zones are the growing severity of droughts/floods and decreasing air quality from increased aerosols. These simultaneous challenges have driven a huge amount of study on the effects of aerosols in influencing Asian monsoon weather and climate during the last decade. An aerosol is a colloid of small solid particles or liquid droplets suspended in air or another gas. The excess volume of aerosol in a certain place will have an impact on the health of living organisms as well as the regional climate. The Asian monsoon area is a major source of aerosol emissions from both man - made and natural sources. Aerosol loading patterns are extensively controlled by diverse meteorological and climatic regimens, which in turn are modified by aerosol impacts. Shipping emissions have garnered attention due to their harmful impact on regional climate and air quality at ports and along coasts across the world. As a result, recognising the aerosol in a certain place is critical. CO2, NOX, and SOX emissions from air pollution cause cloudiness and accelerate climate effect 'Radiative Forcing' (RF). Positive RF causes heat, while negative RF causes cooling. These also have an indirect influence on weather due to the Cloud Condensation Nuclei (CCN) ability of clouds, which has a significant impact of gases and particles. An increase in Sulphur may result in a decrease in Negative RF. Several techniques are applied to assess the range of aerosols, such as LIDAR, photometers, particle analysing methods, and so on; in this case, we utilise a particulate analyser to determine the amount of aerosol. To find out, we maintained the particle counter and analyser on the ship's top deck and examined the aerosol concentration over the atmosphere of the south Indian coast.
