Effects of Temperature on PM2.5 Concentrations in
Rewa, Madhya Pradesh, India

Abstract:

ABSTRACT
The fine particulate matter (PM2.5) problem has appealed much scientific and public attention, due to its effects on, human health, visibility, and global climate. There are three factors that have an important effect on PM2.5 mass concentration: domestic pollutant emission sources, external sources outside of the country, and meteorological conditions. Rewa Madhya Pradesh is a city in the north-eastern part of Madhya Pradesh state in India. The district derives its name from the town of Rewa, the district headquarters, which is another name for the Narmada River. The city lies about 420 kilometers (261 mi) northeast of the state capital Bhopal and 130 kilometers (81 mi) south of the city of Allahabad which is an ideal location to study pollutants from long-range transport and the correlation between PM2.5 and meteorological conditions. In this paper, PM2.5 concentration data and meteorological data were obtained for six months (June-Nov) 2019 at four sites. The spatial distribution depicts that the part of the study area has the most serious PM2.5 pollution. The correlation analysis results between PM2.5 concentration and meteorological data showed that temperature and wind and a negative, and humidity had a positive, correlation with PM2.5.
