Ambient air quality standards and monitoring systems
This area aims to strengthen air quality standards and sustainable national and local air quality monitoring programmes that would enable sufficient understanding of air quality status. India has a national level monitoring network known as National Air Quality Monitoring Programme (NAMP). The network consists of three hundred and forty two (342) operating stations covering one hundred and twenty seven (127) cities/towns in twenty six (26) states and four (4) Union Territories of the country. Of these, 12 cities in India report air quality index (AQI). This is because AQI requires hourly data, which is not possible with most of the stations being manually run. Further AQI requires at least 5 pollutant parameters and most of the air quality monitoring stations report levels of three pollutants – PM10, SOx and NOx.
