'India's first framework for air quality forecast, SAFAR, accepted globally'

New Delhi: India's first official framework for air quality forecast, SAFAR, has been accepted internationally with peer-reviewed Elsevier Journal publishing its findings, founder project director Dr Gufran Beig said on Wednesday.

The framework, mandated under the National Clean Air Programme (NCAP) and developed under the Ministry of Earth Sciences, is being used to make air quality forecasts in Delhi, Mumbai, Pune and Ahmedabad.

The findings of the framework incorporated in a research paper -- India's maiden air quality forecasting framework for megacities of divergent environments: The SAFAR-project -- were published online in peer-reviewed international Elsevier Journal Environmental Modelling and Software on Tuesday.

The Indian Institute of Tropical Meteorology (IITM-Pune) led the research in association with the India Meteorological Department and Utkal University, Bhubaneshwar.

The research revealed that transport is the most dominating source of PM2.5 emissions. It accounts for 41 percent of PM2.5 pollution in Delhi, 40 percent in Pune, 35 percent in Ahmedabad and 31 percent in Mumbai.

The share of biofuel emissions is highest in Mumbai (15.5 percent), followed by Pune (11.4 percent), Ahmedabad (10.2 percent) and Delhi (3 percent), it said.

We chose to demonstrate the SAFAR framework in four different and contrasting micro-climates of Indian cities - Delhi, Mumbai, Pune and Ahmedabad. The prototype can be scaled up to the remaining 128 non-attainment cities of India as per the commitment to NCAP,

Beig said.

NCAP seeks to achieve a 20 to 30 percent reduction in particulate matter (PM) concentrations by 2024, keeping 2017 as the base year.

India has 132 non-attainment cities that do not meet the prescribed air quality standards set by the Union Environment Ministry.
