Regional scale ozone data assimilation using an ensemble Kalman filter and the CHIMERE chemical transport model
Regional scale ozone data ensemble Kalman fi lter
2014/12/18
An ensemble Kalman filter (EnKF) has been coupled to the CHIMERE chemical transport model in order to
assimilate ozone ground-based measurements on a regional
scale. The number of ensembles is...
A method to represent ozone response to large changes in precursor emissions using high-order sensitivity analysis in photochemical models
represent ozone response precursor emissions high-order sensitivity analysis photochemical models
2014/12/12
Photochemical grid models (PGMs) are used to simulate tropospheric ozone and quantify its response to emission changes. PGMs are often applied for annual simulations to provide both maximum concentrat...

2014/12/10
A procedure for tagging ozone produced from NO sources through updates to an existing chemical mechanism is described, and results from its implementation in the Model for Ozone and Related chemical T...
Attribution of ozone changes to dynamical and chemical processes in CCMs and CTMs
Chemical climate models Earth's ozone layer. Coupled chemical plan Simulated atmospheric flow Ozone concentration
2014/12/9
Chemistry-climate models (CCMs) are commonly used to simulate the past and future development of Earth's ozone layer. The fully coupled chemistry schemes calculate the chemical production and destruct...

2010/2/5
The Model for Ozone and Related chemical Tracers, version 4 (MOZART-4) is an offline global chemical transport model particularly suited for studies of the troposphere. The updates of the model from i...
Improved sapflow methodology reveals considerable night-time ozone uptake by Mediterranean species
sapflow methodology considerable night-time ozone Mediterranean species
2010/1/21
Due to the evident tropospheric ozone impact on plant productivity, an accurate ozone risk assessment for the vegetation has become an issue. There is a growing evidence that ozone stomatal uptake may...
Cloud sensitivity studies for stratospheric and lower mesospheric ozone profile retrievals from measurements of limb-scattered solar radiation
Cloud sensitivity stratospheric and lower mesospheric ozone profile limb-scattered solar radiation
2010/2/8
Clouds in the atmosphere play an important role in reflection, absorption and transmission of solar radiation and thus affect trace gas retrievals. The main goal of this paper is to examine the sensit...
