Trends in long-term gaseous mercury observations in the Arctic and effects of temperature and other atmospheric conditions
long-term gaseous mercury observations the Arctic temperature and other atmospheric conditions
2010/8/13
Gaseous elemental mercury (GEM) measurements at Alert, Canada, from 1995 to 2007 were analyzed for statistical time trends and for correlations with meteorological and climate data. A significant decr...
Scale-dependency of surface fluxes in an atmospheric mesoscale model:effect of spatial heterogeneity in atmospheric conditions
Scale-dependency surface fluxes atmospheric mesoscale model spatial heterogeneity
2009/11/2
We examined the nonlinear effect of spatial heterogeneity in atmospheric conditions on the simulation of surface fluxes in the mesoscale model, MM5 by testing their scale-invariance from a tower footp...
Distribution of meteoric smoke – sensitivity to microphysical properties and atmospheric conditions
Distribution of meteoric smoke microphysical properties atmospheric conditions
2009/1/15
Meteoroids entering the Earth's atmosphere experience strong deceleration and ablate, whereupon the resulting material is believed to re-condense to nanometre-size "smoke particles". These particles a...
Estimating the NH3:H2SO4 ratio of nucleating clusters in atmospheric conditions using quantum chemical methods
NH3:H2SO4 quantum chemical methods
2008/12/10
We study the ammonia addition reactions of H2SO4·NH3 molecular clusters containing up to four ammonia and two sulfuric acid molecules using the ab initio method RI-MP2 (Resolution of Identity 2nd orde...
