Socio-economic Concern

  • The presence of heavy and extended period of fog in the northern regions of India is one of the major weather hazards, impacting aviation, road transportation, economy and public life in the world’s most densely populated region.
  • Studies reveal that maximum period of fog occurrence over Northwest India is about 48 days (visibility < 1000m) per year, and occurs mostly during December-February period.
  • Significant socio-economic concern has been raised due to increase in frequency, persistence and intensity of fog occurrence over the northern parts of the country.
  • Land use changes and increasing pollution in the region are responsible for growing fog occurrence.
  • Therefore the campaign, being conducted during Dec 2016 -Feb2017.
  • Measurements when assimilated into models will help to improve the prediction skill of fog formation.
