Transport and build-up of tropospheric trace gases during the MINOS campaign: comparision of GOME, in situ aircraft measurements and MATCH-MPIC-data
The MINOS (Mediterranean INtensive Oxidant Study) campaign was an international, multi-platform field campaign to measure long-range transport of air-pollution and aerosols from South East Asia and Europe towards the Mediterranean basin during August 2001. High pollution events were observed during this campaign. For the Mediterranean region enhanced tropospheric nitrogen dioxide (NO2) and form...
متن کاملTropospheric Aerosol Impacts on Trace-Gas Budgets through Photolysis
Aerosols affect the global budgets of O3, OH and CH4 in part through their alteration of photolysis rates and in part through their direct chemistry interactions with gases (a.k.a. “heterogeneous chemistry”). The first effect is evaluated here with a global tropospheric chemistry transport model using recently developed global climatologies of tropospheric aerosols: a satellite-derived aerosol ...
متن کاملExcitation of the primary tropospheric chemical mode in a global threedimensional model
Coupling of local chemical processes over the globe by atmospheric transport leads to the existence of chemical modes that are a fundamental characterization of global atmospheric chemistry and provide a true description of the atmospheric response to small changes in trace-gas emissions. Such coupled chemistry-transport modes in global tropospheric chemistry are an inherent feature of three-di...
متن کاملMethane and the Ch4–related Greenhouse Effect over the past 400 Million Years
Natural variations in the tropospheric CH4 concentration, excluding short bursts from geospheric reservoirs, have been estimated for the past 400 Ma by scaling a wetland CH4 emission estimate for the middle Pliocene (ca. 3.6–2.6 Ma) by the relative rate of coal basin deposition at any given time in the past. Wetland CH4 fluxes were used as inputs into the Cambridge 2-D chemistry-transport model...
متن کاملDetermining Tropospheric Concentrations of Trace Gases from Space
Background The new observations of the tropospheric distributions of trace gases such as NO2 (nitrogen dioxide), SO2 (sulphur dioxide), HCHO (formaldehyde), BrO (bromine monoxide) and O3 (ozone), retrieved from GOME (Global Ozone Monitoring Experiment) measurements, herald the opening of a new era for tropospheric production, as a result of agricultural activities, and above all by vehicles suc...
