Bromide and other ions in the snow, firn air, and atmospheric boundary layer at Summit during GSHOX
Bromide and other ions atmospheric boundary layer Summit GSHOX
<
2010/10/21
Measurements of gas phase soluble bromide in the boundary layer and in firn air, and Br− in aerosol and snow, were made at Summit, Greenland (72.5° N, 38.4° W, 3200 m a.s.l.) as part of a larger...
Parameterization of vertical diffusion and the atmospheric boundary layer height determination in the EMEP model

Nitrous acid (HONO) plays a significant role in the atmosphere, especially in the polluted troposphere. Its photolysis after sunrise is an important source of hydroxyl free radicals (OH). Measurements...
Exploring atmospheric boundary layer characteristics in a severe SO2 episode in the north-eastern Adriatic
atmospheric boundary layer severe SO2 episode north-eastern Adriatic

Stable atmospheric conditions are often connected with the occurrence of high pollution episodes especially in urban or industrial areas. In this work we investigate a severe SO2 episode observed on 3...
On inferring isoprene emission surface flux from atmospheric boundary layer concentration measurements
isoprene emission surface flux atmospheric boundary layer concentration measurements
<

Atmospheric hydroperoxides (ROOH) were measured at Summit, Greenland (72.97° N, 38.77° W) in summer 2003 (SUM03) and spring 2004 (SUM04) and South Pole in December 2003 (SP03). The two dominant hydrop...
Characterization of the 222Rn family turbulent transport in the convective atmospheric boundary layer
222Rn family turbulent transport convective atmospheric boundary layer
<
2008/12/1
The combined effect of turbulent transport and radioactive decay on the distribution of 222Rn and its progeny in convective atmospheric boundary layers (CBL) is investigated. Large eddy simulation is ...
