Emissions of Organic Compounds in Surfactant Solutions under Air Turbulence
Volatilization rate Volatilization reduction Surfactants Wind Interface concentration
2016/3/25
The objective of this study was to investigate the effects of surfactants aggregating the gas-liquid interface on the
volatilization rates of the organic compounds. The changes in the overall mass tr...
Atmospheric optical-turbulence at Roque de los Muchachos Observatory: database and recalibration of the generalized-SCIDAR data
Atmospheric effects? instrumentation: adaptive optics? Site Testing
2011/9/13
We present the largest database so far of atmospheric optical-turbulence profiles(197035 individual C2N(h)) for an astronomical site, the Roque de los Muchachos Observatory (La Palma, Spain). This C2 ...
Observations of turbulence-induced new particle formation in the residual layer

2010/8/12
Aerosol particle measurements in the atmospheric boundary layer performed by a helicopter-borne measurement payload and by a lidar system from a case study during the IMPACT field campaign in Cabauw (...
Influence of vortex dynamics and atmospheric turbulence on the early evolution of a contrail
vortex dynamics atmospheric turbulence the early evolution of a contrail
2010/8/12
This study describes three-dimensional numerical simulations of the evolution of an aircraft contrail during the first 30 min following the emission of exhausts. The wake is modeled as a vortex pair d...
Turbulence associated with mountain waves over Northern Scandinavia – a case study using the ESRAD VHF radar and the WRF mesoscale model
Turbulence mountain waves Northern Scandinavia the ESRAD VHF radar the WRF mesoscale model
2010/8/12
We use measurements by the 52 MHz wind-profiling radar ESRAD, situated near Kiruna in Arctic Sweden, and simulations using the Advanced Research and Weather Forecasting model, WRF, to study vertical w...
Comment on“Reinterpreting aircraft measurement in anisotropic scaling turbulence”by Lovejoy et al. (2009)
aircraft measurement anisotropic scaling turbulence Lovejoy
2010/2/21
Recently, Lovejoy et al. (2009) argued that the steep ~k−3 atmospheric kinetic energy spectrum at synoptic scales (≥1000 km) observed by aircraft is a spurious artefact of aircraft following iso...
The effect of misleading surface temperature estimations on the sensible heat fluxes at a high Arctic site – the Arctic Turbulence Experiment 2006 on Svalbard (ARCTEX-2006)
misleading surface temperature sensible heat fluxes ARCTEX
2010/1/18
The observed rapid climate warming in the Arctic requires improvements in permafrost and carbon cycle monitoring, accomplished by setting up long-term observation sites with high-quality in-situ measu...
Empirical study of multifractal phase transitions in atmospheric turbulence
Empirical study multifractal phase transitions atmospheric turbulence
2009/11/16
We study atmospheric wind turbulence in the framework of universal multifractals, using several medium resolution (10 Hz) time series. We cut these original time series into 704 scale invariant realiz...
Reinterpreting aircraft measurements in anisotropic scaling turbulence
Reinterpreting aircraft measurements anisotropic scaling turbulence
2009/8/7
Due to both systematic and turbulent induced vertical fluctuations, the interpretation of atmospheric aircraft measurements requires a theory of turbulence. Until now virtually all the relevant theori...
Water-side turbulence enhancement of ozone deposition to the ocean
Water-side turbulence ozone deposition ocean
2008/11/28
A parameterization for the deposition velocity of an ocean-reactive atmospheric gas (such as ozone) is developed. The parameterization is based on integration of the turbulent-molecular transport equa...
Application of the Aventech AIMMS20AQ airborne probe for turbulence measurements during the Convective Storm Initiation Project
Aventech AIMMS20AQ airborne probe turbulence measurements Convective Storm Initiation Project
2008/11/19
The Convective Storm Initiation Project (CSIP) took place during the summers of 2004 and 2005, centred on the research radar at Chilbolton, UK. Precursors to convective precipitation were studied, usi...
