A global three-dimensional model analysis of the atmospheric budgets of HCN and CH3CN: Constraints from aircraft and ground measurements
[1] We construct global atmospheric budgets of HCN and CH3CN through a threedimensional (3-D) model simulation of the HCN-CH3CN-CO system constrained and evaluated with aircraft observations from the Transport and Chemical Evolution Over the Pacific (TRACE-P) mission over the NW Pacific in February–April 2001. Observed background vertical gradients of HCN and CH3CN imply a dominant ocean sink f...
متن کاملImpact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: eutrophication modeling
Atmospheric deposition of nutrients (N and P species) can intensify anthropogenic eutrophication of coastal waters. It was found that the atmospheric wet and dry depositions of nutrients was remarkable in the Southeast Asian region during the course of smoke haze events, as discussed in a companion paper on field observations (Sundarambal et al., 2010b). The importance of atmospheric deposition...
متن کاملAsian monsoon transport of pollution to the stratosphere.
Transport of air from the troposphere to the stratosphere occurs primarily in the tropics, associated with the ascending branch of the Brewer-Dobson circulation. Here, we identify the transport of air masses from the surface, through the Asian monsoon, and deep into the stratosphere, using satellite observations of hydrogen cyanide (HCN), a tropospheric pollutant produced in biomass burning. A ...
متن کاملNeutral production of hydrogen isocyanide (HNC) and hydrogen cyanide (HCN) in Titan’s upper atmosphere
Aims. Following the first detection of hydrogen isocyanide (HNC) in Titan’s atmosphere, we have devised a new neutral chemical scheme for hydrogen cyanide (HCN) and HNC in the upper atmosphere of Titan. Methods. Our updated chemical scheme contains 137 compounds (with C, H, O and N elements) and 788 reactions (including 91 photolysis processes). To improve the chemistry of HNC and HCN, a carefu...
متن کاملAtmospheric tar balls : aged primary droplets from biomass 1 burning ?
10 Atmospheric tar balls are particles of special morphology and composition that are fairly abundant 11 in the plumes of biomass smoke. These particles form a specific subset of brown carbon (BrC) 12 which has been shown to play a significant role in atmospheric shortwave absorption and thus 13 climate forcing. Here we suggest that tar balls are produced by the direct emission of liquid tar 14...
