On the effects of clouds and hazes in the atmospheres of hot Jupiters: semi-analytical temperature-pressure profiles
planets and satellites:atmospheres – radiative transfer
2011/8/16
Abstract: Motivated by the work of Guillot (2010), we present a semi-analytical formalism for calculating the temperature-pressure profiles in hot Jovian atmospheres which includes the effects of clou...
Drift velocity and pressure monitoring of the CMS muon drift chambers
Drift velocity CMS muon drift chambers Instrumentation and Detectors
2011/8/2
Abstract: The drift velocity in drift tubes of the CMS muon chambers is a key parameter for the muon track reconstruction and trigger. It needs to be monitored precisely in order to detect any deviati...
Technical Note: Vapor pressure estimation methods applied to secondary organic aerosol constituents from α-pinene oxidation: an intercomparison study
Vapor pressure estimation methods secondary organic aerosol constituents α-pinene oxidation
2010/8/16
We applied and compared seven vapor pressure estimation methods to the condensable compounds generated in the oxidation of α-pinene, as described by the state-of-the-art mechanism of the BOREAM model ...
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...
Solar cycle signals in sea level pressure and sea surface temperature
Solar cycle signals sea level pressure sea surface temperature
2010/8/12
We identify solar cycle signals in 155 years of global sea level pressure (SLP) and sea surface temperature (SST) data using a multiple linear regression approach. In SLP we find in the North Pacific ...
Technical Note: Measuring condensation sink and ion sink of atmospheric aerosols with the electrical low pressure impactor (ELPI)
condensation sink ion sink atmospheric aerosols ELPI
2010/2/21
We investigate the suitability of ELPI for condensation sink and ion sink measurements. The aim is to find the simple calibration factors by which the measured ELPI current can be converted to condens...

Ozone decomposition kinetics on alumina: effects of ozone partial pressure, relative humidity and repeated oxidation cycles
Ozone decomposition kinetics alumina ozone partial pressure relative humidity repeated oxidation cycles
2009/3/3
The room temperature kinetics of gas-phase ozone loss via heterogeneous interactions with thin alumina films has been studied in real-time using 254nm absorption spectroscopy to monitor ozone concentr...
Surface pressure retrieval from SCIAMACHY measurements in the O2 A Band: validation of the measurements and sensitivity on aerosols
Surface pressure retrieval sensitivity aerosols
2009/2/16
We perform surface pressure retrievals from cloud-free Oxygen A band measurements of SCIAMACHY. These retrievals can be well validated because surface pressure is a quantity that is, in general, accu...
Systematic errors in global air-sea CO2 flux caused by temporal averaging of sea-level pressure
Systematic errors global air-sea CO2 flux temporal averaging sea-level pressure
2009/2/11
Long-term temporal averaging of meteorological data, such as wind speed and air pressure, can cause large errors in air-sea carbon flux estimates. Other researchers have already shown that time averag...
Pressure broadening in the 2ν3 band of methane and its implication on atmospheric retrievals
methane atmospheric retrievals
2008/11/18
N2-broadened half widths and pressure shifts were obtained for transitions in the 2ν3 methane band. Laboratory measurements recorded at 0.011 cm−1 resolution with a Bruker 120 HR Fouriertransfor...
