Improving understanding of atmosphere processes and change


  • Monitoring atmospheric composition and meteorology to detect changes, as well as improve understanding of physical and chemical processes of pollutants’ atmospheric transport, transformations, and removal through the following:

- in situ long-term monitoring stations

- coordinated multi-country field campaigns

- computer modelling and satellite data analysis

  • Monitoring through 13 observatories and air quality stations in Nepal, Bhutan, and Pakistan

  • Installed air quality monitoring stations at altitudes ranging from 100 to 4,900 masl in Nepal (Chitwan, Lumbini, Ratnapark, Pulchowk, Langtang, and Dhulikhel); 200 to 4,100 masl in Bhutan (Gedu, Thimphu, Phuentsholing, Chele la, and Pasakha); and one station in Lahore, Pakistan at 215 masl. The Government of Nepal continues to invest in instruments and containers for air quality monitoring stations, setting up new stations in Kathmandu Valley and across Nepal.
