New system to measure air quality

New system to measure air quality

Context

India is tying up with the United States and Finland to develop a pollution-forecast system that will help anticipate particulate matter (PM) levels at least two days in advance and at a greater resolution than what is possible now. The Ministry of Earth Sciences (MoES) will be coordinating this exercise and the plan is to have a system in place by winter, according to Madhavan Rajeevan, secretary, MoES

New system

• It will use a different method of analysis. This could mean better resolution and more accurate forecasts
• It will be jointly developed with expertise from the Finnish Meteorological Institute and the U.S.’ National Oceanic and Atmospheric Administration
• Focus area: A key focus would be to develop forecasts around the “stubble-burning season” that adds to Delhi’s pollution woes in the winter. This refers to the partially-burnt straw and chaff from fields in Uttar Pradesh and Haryana, when farmers are preparing their fields for the sowing season

Present system in use

Currently, the System of Air Quality and Weather Forecasting and Research (SAFAR), run out of the Indian Institute of Tropical Meteorology (IITM), Pune, serves as the apex forecaster of pollution trends in Delhi, Mumbai, Pune and Ahmedabad.

• It generates a likely air quality profile, a day in advance, for these cities. IITM is an organisation under the MoES
