Author(s):Henning, S.; Wex, H.; Hennig, T.; Kiselev, A.; Snider, Jefferson Robert; Rose, D.; Dusek, U.; Frank, G. P.; Pöschl, U.; Kristensson, A.; Bilde, M.; Tillmann, R.; Kiendler‐Scharr, A.; Mentel, T. F.; Walter, S.; Schneider, J.; Wennrich, C.; Stratmann, F.
The LACIS Experiment in November (LExNo) campaign was conducted in November 2005 at the Atmospheric Composition Change the European Network of Excellence (ACCENT) site Leipzig Aerosol Cloud Interaction Simulator (LACIS). ...
Calibration of the Passive Cavity Aerosol Spectrometer Probe for Airborne Determination of the Size Distribution
Author(s):Cai, Y.; Snider, Jefferson Robert; Wechsler, P.
This work describes calibration methods for the particle sizing and particle concentration systems of the passive cavity aerosol spectrometer probe (PCASP). Laboratory calibrations conducted over six years, in support of ...
Orographic Precipitation in the Tropics : The Dominica Experiment
Author(s):Smith, R. B.; Minder, J. R.; Nugent, A. D.; Storelvmo, T.; Kirshbaum, D. J.; Warren, R.; Lareau, N.; Palany, P. E.; James, A.; French, Jeff
Orographic precipitation influences water resources, flooding and landslides, regional climates, and global water budgets. Progress has also been made on thermally driven island convection in the tropics. In contrast, the ...
Isobaric Height Perturbations Associated with Mountain Waves Measured by Aircraft during the Terrain-Induced Rotor Experiment
Author(s):Parish, Thomas R.; Oolman, Larry D.
It has only been in the last few years that accurate measurement of the horizontal pressure gradient has been possible over complex terrain using an airborne platform. To infer forcing mechanisms for the wind, an independent ...
Assessing the CAM5 Physics Suite in the WRF-Chem Model : Implementation, Resolution Sensitivity, and a First Evaluation for a Regional Case Study
Author(s):Ma, P.-L.; Rasch, P. J.; Fast, J. D.; Easter, R. C.; Gustafson, W. I., Jr.; Liu, Xiaohong; Ghan, S. J.; Singh, B.
A suite of physical parameterizations (deep and shallow convection, turbulent boundary layer, aerosols, cloud microphysics, and cloud fraction) from the global climate model Community Atmosphere Model version 5.1 (CAM5) ...
Organic Aerosol Components Observed in Northern Hemispheric Datasets from Aerosol Mass Spectrometry
Author(s):Ng, N. L.; Canagaratna, M. R.; Zhang, Q.; Jimenez, J. L.; Tian, J.; Ulbrich, I. M.; Kroll, J. H.; Docherty, K. S.; Chhabra, P. S.; Bahreini, R.; Murphy, Shane; Seinfeld, J. H.; Hildebrandt, L.; Donahue, N. M.; Decarlo, P. F.; Lanz, V. A.; Prévôt, A. S. H.; Dinar, E.; Rudich, Y.; Worsnop, D. R.
In this study we compile and present results from the factor analysis of 43 Aerosol Mass Spectrometer (AMS) datasets (27 of the datasets are reanalyzed in this work). The components from all sites, when taken together, ...
Aerosol and Gas Re-Distribution by Shallow Cumulus Clouds : An Investigation Using Airborne Measurements
Author(s):Wonaschuetz, Anna; Sorooshian, Armin; Ervens, Barbara; Chuang, Patrick Y.; Feingold, Graham; Murphy, Shane; de Gouw, Joost; Warneke, Carsten; Jonsson, Haflidi H.
Aircraft measurements during the 2006 Gulf of Mexico Atmospheric Composition and Climate Study (GoMACCS) are used to examine the influence of shallow cumulus clouds on vertical profiles of aerosol chemical composition, ...
