Clouds, photolysis and regional tropospheric ozone budgets
Clouds photolysis regional tropospheric ozone budgets
2009/11/19
We use a three-dimensional chemical transport model to examine the shortwave radiative effects of clouds on the tropospheric ozone budget. In addition to looking at changes in global concentrations as...
Sensitivity studies of the recent new data on O（1D）quantum yields in O3 Hartley band photolysis in the stratosphere
O（1D）quantum yields O3 Hartley band photolysis stratosphere
2009/3/11
The production yields of excited oxygen O(1D) atoms from the near ultraviolet O3 photolysis are essential quantities for atmospheric chemistry calculations because of its importance as major sources o...
Wavelength dependence of isotope fractionation in N2O photolysis
Wavelength dependence isotope fractionation N2O photolysis
2009/3/10
In previous reports on isotopic fractionation in the ultraviolet photolysis of nitrous oxide (N2O) only enrichments of heavy isotopes in the remaining N2O fraction have been found. However, most direc...
Actinic flux and photolysis in water droplets：Mie calculations and geometrical optics limit
Actinic flux photolysis water droplets Mie calculations geometrical optics limit
2009/3/9
Photolysis of water-soluble components inside cloud droplets by ultraviolet/visible radiation may play an important role in atmospheric chemistry. Two earlier studies have suggested that the actinic f...
Actinic flux and O1D photolysis frequencies retrieved from spectral measurements of irradiance at Thessaloniki，Greece

2009/3/9
The results of two methods retrieving actinic flux and ozone photolysis frequencies (JO1D), from measurements of irradiance with a Brewer MKIII spectroradiometer are investigated in this paper. The fi...
NO2 and HCHO photolysis frequencies from irradiance measurements in Thessaloniki, Greece
NO2 HCHO photolysis frequencies Thessaloniki
2009/2/11
An empirical approach for the retrieval of nitrogen dioxide (NO2) and formaldehyde (HCHO) photolysis frequencies from measurements of global irradiance is presented in this work. Four months of synchr...
Near-UV photolysis cross sections of CH3OOH and HOCH2OOH determined via action spectroscopy
Near-UV photolysis CH3OOH HOCH2OOH
2008/12/1
Knowledge of molecular photolysis cross sections is important for determining atmospheric lifetimes and fates of many species. A method and laser apparatus for measurement of these cross sections in t...
Hydrogen isotope fractionation in the photolysis of formaldehyde
Hydrogen isotope fractionation in the photolysis of formaldehyde
2008/10/31
Experiments investigating the isotopic fractionation in the formation of H2 by the photolysis of CH2O under tropospheric conditions are reported and discussed. The deuterium (D) depletion in the H2 pr...
