Sensitivity of stratospheric Bry to uncertainties in very short lived substance emissions and atmospheric transport
stratospheric Bry lived substance emissions atmospheric transport
2011/2/25
We evaluate the sensitivity of Bry entering the stratosphere with a simplified model that allows calculations over a wide parameter range for parameters that are currently poorly quantified. The model...
Emission location dependent ozone depletion potentials for very short-lived halogenated species
Emission location ozone depletion potentials short-lived halogenated species
2010/12/28
We present trajectory-based estimates of Ozone Depletion Potentials (ODPs) for very short-lived halogenated source gases as a function of surface emission location. The ODPs are determined by the frac...
Vertical transport rates and concentrations of OH and Cl radicals in the Tropical Tropopause Layer from observations of CO2 and halocarbons: implications for distributions of long- and short-lived chemical species
Vertical transport rates OH and Cl radicals the Tropical Tropopause Layer long- and short-lived chemical species
2010/8/16
Rates for large-scale vertical transport of air in the Tropical Tropopause Layer (TTL) were determined using high-resolution, in situ observations of CO2 concentrations in the tropical upper troposphe...
Source identification of short-lived air pollutants in the Arctic using statistical analysis of measurement data and particle dispersion model output
short-lived air pollutants Arctic using statistical analysis particle dispersion model output
2010/2/1
As a part of the IPY project POLARCAT (Polar Study using Aircraft, Remote Sensing, Surface Measurements and Models, of Climate Chemistry, Aerosols and Transport), this paper studies the sources of equ...
More evidence for very short-lived substance contribution to stratospheric chlorine inferred from HCl balloon-borne in situ measurements in the tropics

2010/2/1
Volume mixing ratio (vmr) vertical profiles of hydrogen chloride (HCl) are retrieved from in situ measurements performed by a balloon-borne infrared tunable diode laser absorption spectrometer (SPIRAL...
Technical Note: Ensuring consistent, global measurements of very short-lived halocarbon gases in the ocean and atmosphere
Ensuring consistent very short-lived halocarbon gases ocean atmosphere
2010/2/1
Very short-lived halocarbons are significant sources of reactive halogen in the marine boundary layer, and likely in the upper troposphere and lower stratosphere. Quantifying ambient concentrations in...
Modeling the transport of very short-lived substances into the tropical upper troposphere and lower stratosphere
very short-lived substances tropical upper troposphere lower stratosphere
2009/12/31
The transport of very short-lived substances into the tropical upper troposphere and lower stratosphere is investigated by a three-dimensional chemical transport model using archived convective updraf...
Coastal measurements of short-lived reactive iodocarbons and bromocarbons at Roscoff, Brittany during the RHaMBLe campaign
short-lived reactive iodocarbons bromocarbons Roscoff Brittany RHaMBLe campaign
2009/11/19
Atmospheric concentrations of the volatile reactive iodocarbons C2H5I, 1-C3H7I, 2-C3H7I, CH2ICl, CH2IBr, CH2I2 and bromocarbons CH2Br2 and CHBr3 were determined by GC/MS analysis of marine boundary la...
Uptake of HNO3 to deliquescent sea-salt particles: a study using the short-lived radioactive isotope tracer 13N
HNO3 deliquescent sea-salt particles short-lived radioactive isotope tracer 13N
2009/3/12
The uptake of HNO3 to deliquescent airborne sea-salt particles (RH = 55%, P = 760 torr, T = 300 K) at concentrations from 2 to 575 ppbv is measured in an aerosol flow tube using 13N as a tracer. Small...
