Planning your day in Kolkata
Kolkata is in the lower Gangetic region, where air-quality planning includes pollution transported through a shared airshed. For a walk or commute, combine the regional context with a recent reading near the actual route.
Start with central Kolkata, Howrah, the route to your workplace or school. Choose the actual point on the map to compare it with the city-centre location used on this page.
What should you do when pollution rises?
Read the health advice for the index and country you are using. On poorer-air days, consider shortening or rescheduling strenuous outdoor activity. Children and people with heart or lung conditions may need extra care.

Sources and limits
This page shows readings from nearby monitoring stations of public and community networks, such as Sensor.Community, WAQI, OpenAQ, PurpleAir and Syngeos, and in Poland the official GIOŚ network. When no station is nearby, it shows a Copernicus model estimate. Measurements and model values are different kinds of information; a missing or old reading is not evidence of clean air.
