Climatic effects of NOx emissions through changes in tropospheric O3 and CH4: A global 3D model study
Fuglestvedt, Jan S.; Berntsen, Terje; Isaksen, Ivar S. A.; Mao, Huiting; Liang, Xin-Zhong; Wang, Wei-Chyung (CICERO Report;1997:03, Research report, 1997)As a result of chemical processes in the atmosphere, emissions of NOx can both damp and enhance the greenhouse effect. The two most important effects of NOx in this context are increased concentrations of tropospheric ozone ... -
Direct and indirect global warming potentials of source gases
Fuglestvedt, Jan S.; Isaksen, Ivar S. A.; Wang, Wei-Chyung (CICERO Report;1994:01, Research report, 1994)Global Warming Potentials for emissions of CH4, CO and NOx that take into account indirect chemical effects have been estimated for five time horizons. The indirect effects of methane emissions that have been considered ... -
Impacts of reduced NOx emissions on radiative forcing through changes in tropospheric O3 and CH4: A global 3-D model study
Fuglestvedt, Jan S.; Berntsen, Terje; Isaksen, Ivar S. A.; Mao, Huiting; Liang, Xin-Zhong; Wang, Wei-Chyung (CICERO Working Paper;1997:01, Working paper, 1997)A three-dimensional global chemical tracer model and a radiation transfer model have been used to study the role of reduced NOx emissions on radiative forcing. Through production of tropospheric O3, NOx emissions lead to ... -
Responses in tropospheric chemistry to changes in UV fluxes, temperatures and water vapour densities
Fuglestvedt, Jan S.; Jonson, J. E.; Wang, Wei-Chyung; Isaksen, Ivar S. A. (CICERO Report;1994:05, Research report, 1994)A two-dimensional chemistry/transport model of the global troposphere is used to study the chemical response to i) increased UV-radiation from stratospheric ozone depletion and ii) increased temperatures and water vapour ...
