Analysis of 13C and 18O isotope data of CO2 in CARIBIC aircraft samples as tracers of upper troposphere/lower stratosphere mixing and the global carbon cycle
13C and 18O isotope data CO2 CARIBIC aircraft samples the global carbon cycle
2010/9/21
The project CARIBIC (http://caribic-atmospheric.com) aims to study atmospheric chemistry and transport by regularly measuring many compounds in the free troposphere and the upper troposphere/lowermost...
Planetary wave activity in the polar lower stratosphere
Planetary wave activity polar lower stratosphere
2010/2/1
Temperature data from the COSMIC GPS-RO satellite constellation are used to study the distribution and variability of planetary wave activity in the low to mid- stratosphere (15–40 km) of the Arctic a...
What drives the observed variability of HCN in the troposphere and lower stratosphere?

We use the GEOS-Chem global 3-D chemistry transport model to investigate the relative importance of chemical and physical processes that determine observed variability of hydrogen cyanide (HCN) in the...
Evaluation of CLaMS, KASIMA and ECHAM5/MESSy1 simulations in the lower stratosphere using observations of Odin/SMR and ILAS/ILAS-II
CLaMS KASIMA ECHAM5/MESSy1 Odin/SMR ILAS/ILAS-II
2009/8/18
1-year data sets of monthly averaged nitrous oxide (N2O) and ozone (O3) derived from satellite measurements were used as a tool for the evaluation of atmospheric photochemical models. Two 1-year data ...
A three-dimensional model study of long-term mid-high latitude lower stratosphere ozone changes
three-dimensional model long-term mid-high latitude lower stratosphere ozone changes
2009/3/11
We have used a 3D off-line chemical transport model (CTM) to study the causes of the observed changes in ozone in the mid-high latitude lower stratosphere from 1979-1998. The model was forced by Europ...
Variability of the Lagrangian turbulent diffusion in the lower stratosphere
Lagrangian turbulent diffusion lower stratosphere nitrous oxide
2009/2/11
Ozone and nitrous oxide are measured at high spatial and temporal resolution by instruments flying on the ER-2 NASA research aircraft. Comparing the airborne transects to reconstructions by ensemble o...
Modeling of biomass smoke injection into the lower stratosphere by a large forest fire (Part I): reference simulation
biomass smoke lower stratosphere large forest fire
2009/1/20
Wildland fires in boreal regions have the potential to initiate deep convection, so-called pyro-convection, due to their release of sensible heat. Under favorable atmospheric conditions, large fires c...
Observations of meteoric material and implications for aerosol nucleation in the winter Arctic lower stratosphere derived from in situ particle measurements
meteoric material aerosol nucleation winter Arctic lower stratosphere situ particle easurements
2009/1/14
Number concentrations of total and non-volatile aerosol particles with size diameters >0.01 μm as well as particle size distributions (0.4–23 μm diameter) were measured in situ in the Arctic lower str...
The observation of nitric acid-containing particles in the tropical lower stratosphere
nitric acid-containing particles tropical lower stratosphere
2009/1/4
Airborne in situ measurements over the eastern Pacific Ocean in January 2004 have revealed a new category of nitric acid (HNO3)-containing particles in the tropical lower stratosphere. These particles...
Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere
Radiative forcing preindustrial times ozone change troposphere lower stratosphere
2009/1/4
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 a...
