Pressure dependence of the deuterium isotope effect in the photolysis of formaldehyde by ultraviolet light
the deuterium isotope effect the photolysis of formaldehyde ultraviolet light
2010/8/12
The pressure dependence of the relative photolysis rate of HCHO vs. HCDO has been investigated for the first time, using a photochemical reactor at the University of Copenhagen. The dissociation of HC...
Fluorescent biological aerosol particle concentrations and size distributions measured with an Ultraviolet Aerodynamic Particle Sizer (UV-APS) in Central Europe
Fluorescent biological aerosol particle concentrations and size distributions an Ultraviolet Aerodynamic Particle Sizer (UV-APS) Central Europe
2010/8/12
Primary Biological Aerosol Particles (PBAPs), including bacteria, spores and pollen, are essential for the spread of organisms and disease in the biosphere, and numerous studies have suggested that th...
Retrieval of aerosol single scattering albedo at ultraviolet wavelengths at the T1 site during MILAGRO
aerosol single scattering albedo ultraviolet wavelengths MILAGRO
2009/8/18
Surface measurements of direct and diffuse voltages at UV wavelengths were made at the T1 site during the MILAGRO (Megacity Initiative: Local and Global Research Observations) field campaign in March ...
Large-scale validation of SCIAMACHY reflectance in the ultraviolet
Large-scale validation SCIAMACHY reflectance ultraviolet
2009/2/16
In this paper we present an extensive validation of calibrated SCIAMACHY nadir reflectance in the UV (240-400 nm) by comparison with spectra calculated with a fast radiative transfer model. We use ope...
Alternative polarisation retrieval for SCIAMACHY in the ultraviolet
Alternative polarisation SCIAMACHY ultraviolet
2009/2/16
We introduce an alternative method for the retrieval of polarisation in the ultraviolet by the satellite spectrometer SCIAMACHY. Unlike the operational polarisation retrieval algorithm, this method do...

ultraviolet absorption ozone monitors polluted urban environment
2009/1/13
The performance of the EPA Federal Equivalent Method (FEM) technique for monitoring ambient concentrations of O3 via ultraviolet absorption (UV) has been evaluated using data from the Mexico City Metr...
Episode of unusual high solar ultraviolet radiation over central Europe due to dynamical reduced total ozone in May 2005
Episode of unusual high solar ultraviolet radiation central Europe dynamical reduced total ozone
2009/1/8
In late May 2005 unusual high levels of solar ultraviolet radiation were observed over central Europe. In Northern Germany the measured irradiance of erythemally effective radiation exceeded the clima...
Attenuation of global ultraviolet and visible irradiance over Greece during the total solar eclipse of 29 March 2006
global ultraviolet visible irradiance Greece total solar eclipse
2008/12/26
The variability of ultraviolet and photosynthetically active radiation (PAR) during the total solar eclipse of 29 March 2006 was examined in this study. The measurements from NILU-UV multichannel radi...
On the variability of the Ring effect in the near ultraviolet: understanding the role of aerosols and multiple scattering
ultraviolet aerosols multiple scattering
2008/12/1
The "filling-in" (FI) of Fraunhofer lines, often referred to as the Ring effect, was examined using measurements of near ultraviolet sunlight scattered from the zenith sky above Boulder, Colorado duri...
Impact of using different ozone cross sections on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME) ultraviolet measurements
ozone cross sections Global Ozone Monitoring Experiment ultraviolet
2008/11/12
We investigate the effect of using three different cross section data sets on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME) ultraviolet measurements (289–307 nm, 326–337 nm)....
