Abstract

This review paper uses satellite-based data to investigate the complex interaction between aerosols, UV aerosol index, PM2.5, and climatic consequences in the northern region of India. It starts by examining the historical background of air quality and climate change in this area and demonstrates the value of satellite data as an effective tool for tracking these occurrences. This review paper explores the role of aerosols in climate change by utilizing a comprehensive methodology and a wealth of research. It emphasizes the seasonal and geographical fluctuations in aerosol concentrations across Northern India. It also clarifies the significance of the UV aerosol index as a crucial gauge of atmospheric composition, its relationship to air quality, and its effects on climate. In addition, the study examines PM2.5 as a crucial air quality metric and evaluates the region’s health and environmental effects, as well as the particle’s seasonal and regional distribution. Key conclusions about the effects of climate change on Northern India’s weather, temperature swings, and precipitation patterns are compiled from this thorough investigation.
