Short-lived climate pollutants (SLCPs) including black carbon (BC), methane (CH4), and tropospheric ozone (O3) are major climate forcers after carbon dioxide (CO2). These SLCPs also have detrimental impacts on human health and agriculture. Studies sh

Publikováno v: Environmental Pollution. 253:49-60

Carbonaceous aerosols (CAs) scatter and absorb incident solar radiation in the atmosphere, thereby influencing the regional climate and hydrological cycle, particularly in the Third Pole (TP). Here, we present the characteristics of CAs at 19 observa

Kathmandu is the capital city of Nepal and a ‘hotspot’ of urban air pollution in South Asia. Its bowl-shaped structure (altitude 1300 m above sea level (masl); floor area 340 km2) surrounded by tall mountains provides a unique case study for anal

Indoor levels of black carbon and particulate matters in relation to cooking activities using different cook stove-fuels in rural Nepal

Autor: Dipesh Rupakheti, Mark Lawrence, Siva Praveen Puppala, Arnico K. Panday, Maheswar Rupakheti, Ram Kumar Sharma, Nguyen Thi Kim Oanh

Publikováno v: Energy for Sustainable Development. 48:25-33

In Nepal, majority of households still burn solid fuels in inefficient cook stoves inside poorly ventilated kitchens, which results in very high levels of indoor pollutants, including black carbon (BC). Previous studies have not yet reported BC conce

Publikováno v: Aerosol and Air Quality Research. 19:1872-1891

In the present study, we estimated the aerosol radiative forcing and heating rates near Yala Glacier, Nepal (28.21°N, 85.61°E; 4900 masl), using in situ black carbon (BC) mass concentration measurements, satellite data sets, and model simulations.
