C-CARGO, a newly established research group at IESE-NUST (Institute of Environmental Sciences and Engineering- National University of Sciences and Technology) is a step to address the issues of regional air quality and climate change. This research group in collaboration with international partners will play a vital role in exploring the atmospheric composition over Pakistan, in revisiting the existing air quality management procedures, and to help policy makers in developing cost effective and efficient climate change mitigation and adaptation strategies in Pakistan.

Research activities including field expeditions and student thesis are designed in accordance to achieve the following objectives under the umbrella of C-CARGO:

  • Characterize the atmospheric composition over Pakistan
  • Prepare database of different green house and trace gases over Pakistan from Satellite observations
  • continuous monitoring of atmospheric trace gases 
  • Update existing emission inventories
  • Provide timely information to policy makers in order to design policies that are cost effective
  • Address air quality and climate change issues in Pakistan
  • Bridge the gap in atmospheric sciences from local to global scales
Completed  MPhil-Thesis

  • Temporal record of atmospheric NO2 columns over Pakistan using satellite observation
  • Temporal record of tropospheric HCHO columns over Pakistan using satellite observation
  • Temporal record of tropospheric SO2 columns over Pakistan using satellite observation
