How Many Continuous Monitoring Stations are Recommended for Indian Districts and States

Based on thumb rule proposed by CPCB and the district level urban and rural population (as per 2011 census), we estimate the need for 4,000 continuous monitoring stations (2,800 in the urban areas and 1,200 in the rural areas of the districts, as per 2011 census) to spatially, temporally, and statistically represent the PM2.5 pollution in the urban and the rural areas of India.
