Concentration of ozone- its seasonal and temporal variation in Hyderabad
نویسنده
چکیده
Measurement of ozone in the urban environment of Hyderabad was carried out synoptically at four different locations during the year 2011. The amount of ozone in the ambient air varied from 20 μg/m3 to 273 μg/m3 exhibiting wide temporal and seasonal variation. The ozone concentration is invariably peak at noon time and remained high during early summer and spring period. On many occasions 1-h ozone concentration was more than 240 μg /m3 that indicate the maximum 1-h limit of ozone in the ambient air as prescribed by the USEPA. The results of the study show that there is a significant increase of tropospheric ozone in the urban environment of Hyderabad.

Surface ozone (Surface O3)is a secondary pollutant and there are only limited studies on ozone in South India. Studies have revealed a strong correlation between higher ozone levels and warmer days. Surface O3 along with its precursors like NO2, CO and CH4 are being measured at Kanyakumari (8.0780° N, 77.5410° E), TamilNadu, India and in this paper we present the summer time variation of ozone ...
