Estimating European emissions of ozone-depleting and greenhouse gases using observations and a modeling back-attribution technique

摘要: [1] The Numerical Atmospheric Dispersion Modeling Environment (NAME) dispersion model driven by three-dimensional (3-D) synoptic meteorology from the Unified Model has been used to determine fraction of air arriving at Mace Head, Ireland, different European regions over a 6-year period. These data, along with observations pollutants Head and best fit algorithm, have derive emission estimates Western Europe. The algorithm starts randomly generated maps iterates toward solution. Using an idealized case study, it shown be effective distinguishing between distinct source regions. technique applied two ozone-depleting gases, CFC-11 CFC-12, greenhouse methane nitrous oxide. emissions derived compare favorably existing inventories. is able provide information regarding distribution across Europe estimate area country contributions; that for some species not readily available other means. It methodology those currently so useful tool in verifying
