libmpdata++ 1.0: a library of parallel MPDATA solvers for systems of generalised transport equations
Structured grids numerical dynamic system transmission nonlinear stability
2015/5/18
This paper accompanies the first release of libmpdata++, a C++ library implementing the multi-dimensional positive-definite advection transport algorithm (MPDATA) on regular structured grid. The libra...
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...
Modelling multi-phase halogen chemistry in the coastal marine boundary layer: investigation of the relative importance of local chemistry vs. long-range transport
multi-phase halogen chemistry the coastal marine boundary layer local chemistry long-range transport
2011/2/25
Measurements of significant concentrations of IO, I2 and BrO in a semi-polluted coast environment at Roscoff, in North-West France, have been made as part of the Reactive Halogens in the Marine Bounda...
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...
Attribution of stratospheric ozone trends to chemistry and transport: a modelling study
stratospheric ozone chemistry transport a modelling study
2010/12/28
The decrease of the concentration of ozone depleting substances (ODSs) in the stratosphere over the past decade raises the question to what extent observed changes in stratospheric ozone over this per...
Measurements and modelling of molecular iodine emissions, transport and photodestruction in the coastal region around Roscoff
molecular iodine photodestruction the coastal region around Roscoff
2010/12/28
Iodine emissions from the dominant six macroalgal species in the coastal regions around Roscoff, France, have been modelled to support the Reactive Halogens in the Marine Boundary Layer Experiment (RH...
Quantifying transport into the Arctic lowermost stratosphere
the Arctic lowermost stratosphere the Arctic vortex the Arctic winter 2003
2010/12/28
In the Arctic winter 2003, in-situ measurements of the long-lived trace gases N2O, CFC-11 (CCl3F), H-1211 (CBrClF2), CH4, O3 and H2O have been performed on board the high-altitude aircraft M55 Geophys...
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 ...
