Winter Fog Monitoring

During ICIMOD’s Second Annual Regional Atmospheric Science Workshop that took place in Pokhara, Nepal in June 2014, scientists from the region expressed enthusiasm to carry out a comprehensive study of the persistent winter fog that often afflicts the plains of northern South Asia (often referred to as the Indo-Gangetic Plains, IGP) and its surroundings during winter. Recently, ICIMOD hosted a meeting during 02-03 December, 2014, in Kathmandu Nepal, to discuss plans for a pilot study in the recent winters (2014-15) and a full-scale field study afterwards.

Consequently, a team of Pakistani scientists comprising Dr Muhammad Fahim Khokhar (principal investigator) from NUST and Dr Imran Shahid from IST along with other collaborators from LUMS, SUPPARCO and UET Lahore started monitoring of winter fog at different locations of Lahore city. LUMS's Physlab has played an active role in the fog monitoring this winter season (2014-15) by installing a monitoring station, in order to monitor the atmospheric composition during these special meteorological conditions, unique to the Indo-Ganges plains.

The ultimate goals of this project are:

  • to understand better when and how the persistent fog forms,
  • to identify human activities that are contributing to it,
  • mitigation options that may reduce the fog formation.
  • possibility to forecast it,
  • provide guidance to government agencies.

Currently, the acquired data is being analyzed and chemical analysis of the condensed fog is being conducted.
