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...
Transport of dust particles from the Bodélé region to the monsoon layer – AMMA case study of the 9–14 June 2006 period
dust particles the Bodélé region the monsoon layer the 9–14 June 2006 period
2011/1/20
Aerosol properties were measured during an airborne campaign experiment that took place in June 2006 in West Africa within the framework of the African Monsoon Multidisciplinary Analyses (AMMA). The g...
Insight from ozone and water vapour on transport in the tropical tropopause layer (TTL)
ozone and water vapour the tropical tropopause layer (TTL)
2011/1/19
We explore the potential of ozone observations to constrain transport processes in the tropical tropopause layer (TTL), and contrast it with insights that can be obtained from water vapour. Global fie...
Observation operator for the assimilation of aerosol type resolving satellite measurements into a chemical transport model
aerosol type satellite measurements a chemical transport model
2010/11/29
Modelling of aerosol particles with chemical transport models is still based mainly on static emission databases while episodic emissions cannot be treated sufficiently. To overcome this situation, a ...
The influence of biomass burning and transport on tropospheric composition over the tropical Atlantic Ocean and Equatorial Africa during the West African monsoon in 2006
biomass burning and transport tropospheric composition the tropical Atlantic Ocean and Equatorial Africa the West African monsoon
2010/10/21
Biomass burning (BB) in southern Africa is the largest emission source of CO and O3 precursors within Africa during the West African Monsoon (WAM) between June and August. The long range transport and...
Long-term trends of black carbon and sulphate aerosol in the Arctic: changes in atmospheric transport and source region emissions
black carbon sulphate aerosol the Arctic atmospheric transport source region emissions
2010/10/11
To reveal the contribution of different source regions on these trends, we used a cluster analysis of the output of the Lagrangian particle dispersion model FLEXPART run backward in time from the meas...
Transport timescales and tracer properties in the extratropical UTLS
Transport timescales tracer properties the extratropical UTLS
2010/9/1
A comprehensive evaluation of seasonal backward trajectories initialized in the northern hemisphere lowermost stratosphere (LMS) has been performed to investigate the factors that determine the tempor...
Transport of North African dust from the Bodélé depression to the Amazon Basin: a case study
North African dust the Bodélé depression the Amazon Basin
2010/8/25
This case study follows the dust events of 11–16 and 18–27 February 2008, from the emission in the Bodélé over West Africa (most likely with contribution from other dust sources in the region) the cro...

Long-range pollution transport the MILAGRO-2006 campaign a major Mexico City outflow event free-floating altitude-controlled balloons
2010/8/16
One of the major objectives of the Megacities Initiative: Local And Global Research Observations (MILAGRO-2006) campaign was to investigate the long-range transport of polluted Mexico City Metropolita...
Satellite observations of long range transport of a large BrO plume in the Arctic
Satellite observations a large BrO plume the Arctic
2010/8/16
In this study, BrO measurements from the satellite instrument GOME-2 are used together with model calculations with the dispersion model FLEXPART to study an arctic BrO event in March 2007, which coul...
Long range transport of mercury to the Arctic and across Canada
Long range transport mercury the Arctic Canada
2010/8/16
This study is the most extensive study to date on the transport of mercury to the Arctic. Moreover, it is the first such study to use a fully-coupled, online chemical transport model, Environment Cana...
The Coupled Aerosol and Tracer Transport model to the Brazilian developments on the Regional Atmospheric Modeling System (CATT-BRAMS) – Part 2: Model sensitivity to the biomass burning inventories
