India NCAP – 131 Cities and Designated Airsheds

Updated: March, 2023

131 NCAP non-attainment cities are grouped into 104 airsheds. Of these airsheds, 73 contain only one city; 18 contain two cities, and nine contain three cities. Four airsheds – Delhi, Mumbai, Indore, and Chandigarh contain 10, 8, 5, and 5 cities respectively. An additional 33 cities, not on the NCAP list are also part of these airsheds.

In the table below, the designated airsheds are presented in a grid-format as a Google Earth enabled KML file and as a CSV file with data on grid no. (starting with the southwest corner going left to right and bottom to top), SW and NE corners and mid-points of each grid, and grid area in sq.km. For each of the designated airsheds, an infographic (click on image) containing airshed extent with roads and some useful details is also available.
