India Air Quality Forecasts – District Average Hourly Timeseries

Air pollution has emerged as a top-10 risk factor for human health in India and the cities are increasingly exceeding the national ambient standards and the World Health Organizations guidelines for criteria pollutants. To support India’s air pollution management framework, modeled 24-hr (daily) average ambient concentrations were simulated for the next 72-hours, using meteorology processed through 3D-WRF meteorological model and the GFS meteorological fields and the concentrations simulated through the CAMx chemical transport modeling system, coupled to a dynamic emissions inventory. The modeling domain covers the Indian subcontinent at a spatial resolution of 0.25° x 0.25° degrees (~25 km 25 km) and a temporal resolution of 1 hour. All the simulation fields are updated everyday at 21:00 local time.

The modeling domain includes 640 districts covering 36 states (including Union Territories). The district designations are as per the 2011 census board specifications. First select the state and then a district from the second drop down menu.

When comparing the numbers below with the real time monitoring data, keep in mind that these are district averages and the data coming from the monitoring stations is a point measurement. It is also a good practice to keep an eye on the meteorological fields, which tend to significantly impact the prevalent concentrations (for example, wet conditions mean lesser pollution, windy conditions mean more entrainment, etc.).

The data fields are updated everyday at ~21:00 IST.
