India NCAP – Airshed Ambient Monitoring Needs

NCAP Airshed InformationUpdated: March, 2023

131 NCAP non-attainment cities are grouped into 104 airsheds. For each airshed, we defined (a) the size of NCAP city airsheds (b) the recommended number of ambient air quality monitoring sites in an airshed (c) the operational sampling frequency to support receptor-based source apportionment studies. These resources are necessary for strengthening the monitoring needs of an airshed to track pollution levels, to conduct receptor-model-based source apportionment studies, and to support long-term air quality management plans.

The table below presents details at the airshed level on (a) NCAP and non-NCAP cities (b) minimum number of monitors recommended for monitoring PM, SO2, NO2, CO, and other pollutants and (c) an infograph with additional information on the airshed – size, built-up area share, total population, and urban population share.
