Abstract

In the present pandemic scenario in the world due to Corona virus, the quality of air is one of the most influencing factors for all our livelihoods. We present the brief details with limited data of continuous monitoring system of air quality for few months during the period Feb 2023 to April 2023. The continuous air quality monitoring station at our Institute is implemented by Tamil Nadu Pollution Control Board (TNPCB), Government of Tamil Nadu in the year 2021. It indicates that the Air Quality Index is 13% that can be considered as very good and provides minimal impact on 87% of the air. The Air Pollutant Standard Index includes PM10 and PM2.5 parameters. The other monitoring parameters are O3, NOx, SO2, CO, NH3, WS (m/s), Solar Radiation (w/m²), WD (°), RH (%), BP (mbar) and Rain (mm). The results of one-day data analysis have shown more than one Eigen value and no negative Eigen values. Air Quality and Health issues through Factor analysis. Data need to be efficiently integrated from all the other stations and transfer to a center with real-time information using sensors. 3D graphs for 12 different parameters considering 3 months’ data are presented for better visualization and comparison.
