“…Comparisons between MELCHIOR2 and three detailed mechanisms (MCM, Jenkin et al, 2003;SAPRC99, Carter, 2000; GECKO-A, Aumont et al, 2005) show a good agreement between the chemical schemes, with differences in HCHO yields under low-and high-NO conditions lower than 20 % between the simulated results (Dufour et al, 2009). SAPRC99 chemical mechanism had already been used in CHIMERE for particular studies (Lasry et al, 2007;Coll et al, 2009) but had never been distributed in a previous CHIMERE release.…”

CHIMERE-2017: from urban to hemispheric chemistry-transport modeling

Abstract. CHIMERE is a chemistry-transport model designed for regional atmospheric composition. It can be used at a variety of scales from local to continental domains. However, due to the model design and its historical use as a regional model, major limitations had remained, hampering its use at hemispheric scale, due to the coordinate system used for transport as well as to missing processes that are important in regions outside Europe. Most of these limitations have been removed in the CHIMERE-2017 version, allowing its use in any region of the world and at any scale, from the scale of a single urban area up to hemispheric scale, with or without polar regions included. Other important improvements have been made in the treatment of the physical processes affecting aerosols and the emissions of mineral dust. From a computational point of view, the parallelization strategy of the model has also been updated in order to improve model numerical performance and reduce the code complexity. The present article describes all these changes. Statistical scores for a model simulation over continental Europe are presented, and a simulation of the circumpolar transport of volcanic ash plume from the Puyehue volcanic eruption in June 2011 in Chile provides a test case for the new model version at hemispheric scale.

“…The CHIMERE outputs, for all the ESCOMPTE observation periods, have been closely evaluated within the framework of a CTM intercomparison exercise associated to the project, and through classic statistical indexes of measurementemodel comparison. These analyses revealed a satisfactory behaviour of the model on the area with very few missed exceedances of the ozone regulatory thresholds and a good representation of the ozone plume location and intensity (see Coll et al, 2009 for more details). The CHIMERE model was run in this validated configuration for a selected 4-day period running from 23 to 26 June 2001, which corresponds to the main pollution episode of the ESCOMPTE campaign, and representing the most common meteorological pollution situation of the region.…”

This paper presents an evaluation of the consistency of an urban state-of-the-art hydrocarbon (HC) emission inventory. The evaluation was conducted through the comparison of this inventory with hourly HC measurements during two summer months in the centre of Marseille, on the Mediterranean French coast. Factors of under or overestimation could be calculated for each compound on the basis of a systematic HC to HC ratio analysis. These results, associated with a deep analysis of the speciation profiles, show that most of the common and highly concentrated hydrocarbons (such as butanes) are too much predominant in the emission speciation, while the heavy and less common species (branched alkanes, substituted aromatics) are under-represented in the inventory. The urban diffuse sources appear here as one critical point of the inventories. The disagreements were shown to have a strong incidence on the representation of the air mass reactivity. In a last step, the identified uncertainties in emissions were implemented in an air-quality model for sensitivity studies. It was shown that the observed biases in the inventory could affect the regional ozone production, with a probable impact on ozone peaks of 2e10 ppbv over the area.

Abstract. CHIMERE is a chemistry-transport model initially designed for box-modelling of regional atmospheric composition. In the past decade, it has been converted into a 3D eulerian model that could be used at a variety of scales from local to continental domains. However, due to the model design and its historic use as a regional model, major limitations had remained, prohibiting its use at hemispheric scale, due to the coordinate system used for transport as well as to missing processes that are important in regions outside Europe. Most of these limitations have been lifted in the CHIMERE-2016 version, allowing its use in any region of the world and at any scale, from the scale of a single urban area up to hemispheric scale, including or not polar regions. Other important improvements have been brought in the treatment of the physical processes affecting aerosols and the emissions of mineral dust. From a computational point of view, the parallelization strategy of the model has also been improved in order to improve model numerical performance. The present article describes all these changes. Scores for a model simulation over continental Europe are presented, and a simulation of the circumpolar transport of volcanic ash plume from the Puyehue volcanic eruption in June 2011 in Chile provides a test case for the new model version at hemispheric scale.
