SAFAR: Most advanced System of Air Quality and Weather Forecasting inuagrated in Delhi

Ministry of Earth Sciences has unveiled state-of-the-art Air Quality and Weather Forecast System– SAFAR (System of Air Quality and Weather Forecasting) at Chandni Chowk in Delhi. It is first of its kind and most advanced system in India. Such advanced are also proposed to be implemented in other three cities of India- Pune, Mumbai and Ahmedabad.

SAFAR (System of Air Quality and Weather Forecasting)

SAFAR was developed indigenously by Indian Institute of Tropical Meteorology (IITM), Pune and operationalized by India Meteorological Department (IMD). It is integral part of India’s first Air Quality Early Warning System operational in Delhi. It will monitor all weather parameters like temperature, rainfall, humidity, wind speed and wind direction.

It also will measure sun’s UV-Index (UVI), PM1, Mercury and Black carbon in real time in addition to regular air quality and weather parameters like PM2.5, PM10, Sulfur Dioxide, Ozone, Nitrogen Oxides, Carbon Monoxide. It can also provide measurement of online automatic ultrafine particles PM1 and Mercury, both of which have direct relevance to human health. It will also monitor existence harmful pollutants of Benzene, Toluene and Xylene.

SAFAR has giant true colour LED display which gives out real-time air quality index on 24×7 basis with colour coding alongwith 72-hour advance forecast. Based on Air Quality Index on particular day, health advisory and related precaution will be notified to prepare citizens well in advance.

Benefits

SAFAR will accelerate public awareness and preparedness of air pollution and weather extremes. It will also lead to better understanding of linkages among emissions, weather, pollution and climate. It will strengthen existing air quality network of SAFAR, Central Pollution Control Board (CPCB) and Delhi Pollution Control Committee (DPCC). Besides health, SAFAR system will benefit cost savings to several other sectors like agriculture, aviation, infrastructure, disaster management skill, tourism and many others, which directly or indirectly get affected by air quality and weather.

Government to tie up with US and Finland to jointly develop new pollution-forecast system

The Ministry of Earth Sciences (MoES) is tying up with US and Finland to develop new pollution-forecast system that will help anticipate particulate matter (PM) levels at least two days in advance and at greater resolution. The new system will jointly developed with expertise from Finnish Meteorological Institute and US National Oceanic and Atmospheric Administration (NOAA).

Background

Currently, System of Air Quality and Weather Forecasting and Research (SAFAR), run out of Indian Institute of Tropical Meteorology (IITM), Pune, serves as apex forecaster of pollution trends in Delhi, Mumbai, Pune and Ahmedabad. It generates likely air quality profile for a day in advance, for these cities. SAFAR monitors pollutants like PM1, PM2.5, PM10, NOx (NO, NO2), CO, Ozone, SO2, BC, Methane (CH4), Non-methane hydrocarbons (NMHC), Benzene, VOC’s, Mercury.

Recently, Union Environment Ministry also had released draft of National Clean Air Programme (NCAP) that aims to improve air quality monitoring in India by increasing number of pollution monitoring stations and, incorporating it into a pollution forecast system.

New pollution-forecast system

The new system will use a different modelling approach as well as computational techniques from that employed in the SAFAR model. SAFAR will continue to be the backbone for pollution forecast but this new system will use different method of analysis for better resolution and more accurate forecasts.
