Autor: J. Girdwood, H. Smith, W. Stanley, Z. Ulanowski, C. Stopford, C. Chemel, K.-M. Doulgeris, D. Brus, D. Campbell, R. Mackenzie

Publikováno v: Atmospheric Measurement Techniques, Vol 13, Pp 6613-6630 (2020)

Small unmanned aircraft (SUA) have the potential to be used as platforms for the measurement of atmospheric particulates. The use of an SUA platform for these measurements provides benefits such as high manoeuvrability, reusability, and low cost when

Insights into the deterministic skill of air quality ensembles from the analysis of AQMEII data

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 15629-15652 (2016)

Simulations from chemical weather models are subject to uncertainties in the input data (e.g. emission inventory, initial and boundary conditions) as well as those intrinsic to the model (e.g. physical parameterization, chemical mechanism). Multi-

Ozonesonde profiles from the West Pacific Warm Pool: measurements and validation

Autor: R. Newton, G. Vaughan, H. M. A. Ricketts, L. L. Pan, A. J. Weinheimer, C. Chemel

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 619-634 (2016)

We present a series of ozonesonde profiles measured from Manus Island, Papua New Guinea, during February 2014, with new insights on the calibration of ozonesondes for measurements in the tropical troposphere. The experiment formed a part of a wide

Evaluating the capability of regional-scale air quality models to capture the vertical distribution of pollutants

Publikováno v: Geoscientific Model Development, Vol 6, Iss 3, Pp 791-818 (2013)

This study is conducted in the framework of the Air Quality Modelling Evaluation International Initiative (AQMEII) and aims at the operational evaluation of an ensemble of 12 regional-scale chemical transport models used to predict air quality over t

Representation of tropical deep convection in atmospheric models – Part 2: Tracer transport

Publikováno v: Atmospheric Chemistry and Physics, Vol 11, Iss 15, Pp 8103-8131 (2011)

The tropical transport processes of 14 different models or model versions were compared, within the framework of the SCOUT-O3 (Stratospheric-Climate Links with Emphasis on the Upper Troposphere and Lower Stratosphere) project. The tested models range

Representation of tropical deep convection in atmospheric models – Part 1: Meteorology and comparison with satellite observations

Autor: M. R. Russo, V. Marécal, C. R. Hoyle, J. Arteta, C. Chemel, M. P. Chipperfield, O. Dessens, W. Feng, J. S. Hosking, P. J. Telford, O. Wild, X. Yang, J. A. Pyle

Publikováno v: Atmospheric Chemistry and Physics, Vol 11, Iss 6, Pp 2765-2786 (2011)

Fast convective transport in the tropics can efficiently redistribute water vapour and pollutants up to the upper troposphere. In this study we compare tropical convection characteristics for the year 2005 in a range of atmospheric models, including

Estimating the diffusive heat flux across a stable interface forced ewpage by convective motions

Autor: C. Chemel, C. Staquet, J.-P. Chollet

Publikováno v: Nonlinear Processes in Geophysics, Vol 17, Iss 2, Pp 187-200 (2010)

Entrainment at the top of the convectively-driven boundary layer (CBL) is revisited using data from a high-resolution large-eddy simulation (LES). In the range of values of the bulk Richardson number RiB studied here (about 15–25), the entrainment

Modelling photochemistry in alpine valleys

Autor: G. Brulfert, C. Chemel, E. Chaxel, J. P. Chollet

Publikováno v: Atmospheric Chemistry and Physics, Vol 5, Iss 9, Pp 2341-2355 (2005)

Road traffic is a serious problem in the Chamonix Valley, France: traffic, noise and above all air pollution worry the inhabitants. The big fire in the Mont-Blanc tunnel made it possible, in the framework of the POVA project (POllution in Alpine Vall
