Angular distribution of Bremsstrahlung photons and of positrons for calculations of terrestrial gamma-ray flashes and positron beams
Bremsstrahlung pair production analytical integration of Bethe-Heitler equation distribution of scattering angles
2012/2/28
Within thunderstorms electrons can gain energies of up to hundred(s) of MeV. These electrons can create X-rays and gamma-rays as Bremsstrahlung when they collide with air molecules. Here we calculate ...
The impact of MM5 and WRF meteorology over complex terrain on CHIMERE model calculations
MM5 WRF meteorology CHIMERE model calculations
2009/9/14
The objective of this study is to evaluate the impact of meteorological input data on calculated gas and aerosol concentrations. We use two different meteorological models (MM5 and WRF) together with ...
Hohenpeissenberg Photochemical Experiment（HOPE 2000）：Measurements and photostationary state calculations of OH and peroxy radicals
Hohenpeissenberg Photochemical Experiment HOPE OH peroxy radicals
2009/3/11
Measurements of OH, total peroxy radicals, non-methane hydrocarbons (NMHCs) and various other trace gases were made at the Meteorological Observatory Hohenpeissenberg in June 2000. The data from an in...
Spatial variation of aerosol properties over Europe derived from satellite observations and comparison with model calculations
aerosol properties Europe satellite observations model calculations
2009/3/10
Aerosol optical depths (AOD) and Angström coefficients over Europe were retrieved using data from the ATSR-2 radiometer on board the ESA satellite ERS-2, for August 1997. Taking advantage of the ...
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...
Model calculations of the age of firn air across the Antarctic continent
Model calculations firn air Antarctic continent
2009/3/4
The age of firn air in Antarctica at pore close-off depth is only known for a few specific sites where firn air has been sampled for analyses. We present a model that calculates the age of firn air at...
Technical note: The libRadtran software package for radiative transfer calculations - description and examples of use
libRadtran software package radiative transfer calculations
2009/2/12
The libRadtran software package is a suite of tools for radiative transfer calculations in the Earth's atmosphere. Its main tool is the uvspec program. It may be used to compute radiances, irradiances...
Observations and model calculations of trace gas scavenging in a dense Saharan dust plume during MINATROC
trace gas scavenging dense Saharan dust MINATROC
2009/2/12
An intensive field measurement campaign was performed in July/August 2002 at the Global Atmospheric Watch station Izaña on Tenerife to study the interaction of mineral dust aerosol and troposph...
The impact of air pollutant and methane emission controls on tropospheric ozone and radiative forcing: CTM calculations for the period 1990-2030
air pollutant methane emission tropospheric ozone CTM
2009/2/12
To explore the relationship between tropospheric ozone and radiative forcing with changing emissions, we compiled two sets of global scenarios for the emissions of the ozone precursors methane (CH4), ...
