Rajasthan Government launches Mobile App RajVayu on Air Quality Index

Rajasthan Government has launched mobile application RajVayu for sharing information about air quality index of Jaipur, Udaipur and Jodhpur.

The app was launched by Rajasthan Chief Minister Vasundhara Raje on the eve of World Environment Day (5th June). With this, Rajasthan becomes first state in country to launch such app for sharing information about air quality index of cities.

 Key features of RajVayu

  • Information provided on RajVayu app is based on the data collected by sophisticated air quality monitoring equipment and weather sensors.
  • The app has been designed by Rajasthan State Pollution Control Board (RSPCB) jointly with Indian Institute of Tropical Meteorology (IITM).
  • It would share details about the air quality, such as levels of pollutants likes SOx, NOx, CO, Ozone particles and Particulate Matter (PM) with the city residents and tourists.
  • It would also share temperature, wind speed, humidity, weather forecast and advisories.
  • This app is based on the System of Air Quality and Weather Forecasting Research (SAFAR-India) which is presently connected in Delhi, Mumbai and Pune.

By 2017, the services of this application would be expanded other cities in the state including in Ajmer, Alwar, Bhiwadi, Kota and Pali.

Besides, CM Vasundhara Raje also launched another application named ‘Drishti’ for monitoring of pollution levels in industrial regions. It has been designed by the RSPCB with the support from RajComp.

The Central Pollution Control Board (CPCB) has released National Air Quality Indices (AQI) for 24 cities across India in the month of January 2016.

In the list Varanasi (Uttar Pradesh) and Muzzafarpur (Bihar) were on the top with an AQI value of 409 points each and were coded as ‘severe’ in terms of air pollution in January 2016.

Key facts

  • Faridabad (Haryana), Patna (Bihar) and Agra (Uttar Pradesh) were placed at 3rd, 4th and 5th position with 399, 388 and 372 points respectively.
  • The national capital Delhi was placed at the 6th position with 362 points and was coded as ‘very poor’ in terms of air pollution. Earlier in December 2015, it was coded as ‘Poor’ in with 293 points.

Earlier in September 2015 and October 2015, Delhi was at the top in the AQI i.e. in terms of air pollution chart. The World Health Organization (WHO) also had earlier termed Delhi as one of the most polluted city in the world in terms of air pollution.

About National Air Quality Index

  • The National AQI is published for every month by CPCB along with a numerical value and a colour code which helps in comparing air pollution levels in cities.
  • It is determined on the basis of concentration of 8 pollutants, including Particulate Matter (PM 2.5, PM 10), sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3), ammonia (NH3) and lead (Pb).
  • The colour categories are classified into 6 categories depending upon numerical value as Good (0-50), Satisfactory (51-100), Moderately polluted (101-200), Poor (201-300), Very poor (301-400) and Severe (401-500).
