Air Pollutions Big Data Analysis of DELHI's Climate Resilience

Abstract Aerosols, minute suspended particulate matter (PM) in the atmosphere, originate from various natural and anthropogenic sources. The physical and chemical properties of atmospheric aerosols depend on their sources and interaction with other gaseous species in the atmosphere. The fine aerosols below the size 2.5-micrometer diameter (PM2.5) are an integral part of air pollution that can penetrate deeply into the lungs and cause health problems associated with the respiratory system. The levels of PM 2.5 in the metropolitan city (e.g. Delhi) are often found to exceed the Indian National Ambient Air Quality Standards (NAAQS). Delhi's air quality has once again plunged into the 'Severe Category’, with the 24-hour average Air Quality Index (AQI) reaching 401 at 6 PM today. In Short; 19 of 39 stations in Delhi report AQI above 400, and Jahangirpuri records the highest AQI at 445 anti-pollution measures under GRAP IV in place. Delhi National Capital Region (Delhi-NCR) is facing serious challenges linked to worrying levels of air pollution (mainly NO2, PM10, and PM2.5). This research studies related to the ‘Clean Air Mission’ to enact or coordinate policies related to air pollution is warranted. The air pollution control, stringent enough to protect public health in India, can be done only with a coordinated effort across the national, state, and city levels, and across multiple ministries (transportation, power, industry, rural and urban development, health, agriculture, and others). The Air Quality Index (AQI) is a system used to measure the concentration of five major air pollutants: ground-level ozone, particulate matter (PM), carbon monoxide, nitrogen dioxide, and sulfur dioxide. Established by the Environmental Protection Agency (EPA). Now, the AQI ranges from 0 to 500, with higher numbers indicating worse air quality. An AQI of 0 to 100 signals air that is considered safe for most people, with minimal risk of health effects. When the AQI exceeds 100, air quality can begin to affect sensitive groups, and when it is above 200, it poses serious health risks for the general population. The average AQI levels of Delhi as of today are 450 to 500, this work summarizes all the Seasonal Chemicals and Air Pollutants and presents the research studies with analytical data with tabulated and graphical interpretation. This paper offers insight by reviewing the influence of Delhi’s urban growth since 1990 on pollution levels and sources and the evolution of technical, institutional, and legal measures to control emissions in the National Capital Region of Delhi
