Numerical wind wave model with a dynamic boundary layer
wind wave model dynamic boundary layer
2009/11/12
A modern version of a numerical wind wave model of the fourth generation is constructed for a case of deep water. The following specific terms of the model source function are used: (a) a new analytic...
Using ground-based solar and lunar infrared spectroscopy to study the diurnal trend of carbon monoxide in the Mexico City boundary layer
ground-based solar lunar infrared spectroscopy diurnal trend carbon monoxide Mexico City boundary layer
2009/11/9
Carbon monoxide (CO) is an important pollutant in urban agglomerations. Quantifying the total burden of this pollutant in a megacity is challenging because not only its surface concentration but also ...

Influence of stability flux-profile relationships wind speed Φm Φh atmospheric boundary layer
2009/11/9
Data from SABLES98 experimental campaign have been used in order to study the influence of stability (from weak to strong stratification) on the flux-profile relationships for momentum, Φm, and heat, ...
Cloud condensation nuclei measurements in the marine boundary layer of the Eastern Mediterranean: CCN closure and droplet growth kinetics
marine boundary layer Eastern Mediterranean CCN closure droplet growth kinetics
2009/9/27
Measurements of cloud condensation nuclei (CCN) concentrations (cm−3) between 0.2 and 1.0% supersaturation, aerosol size distribution and chemical composition were performed at a remote marine s...

Low-Z particle electron probe X-ray microanalysis (low-Z particle EPMA) shows powerful advantages for the characterization of ambient particulate matter in environmental and geological applications. B...
Observations of high rates of NO2-HONO conversion in the nocturnal atmospheric boundary layer in Kathmandu, Nepal
NO2-HONO conversion nocturnal atmospheric boundary layer Kathmandu Nepal
2009/9/11
Nitrous acid (HONO) plays a significant role in the atmosphere, especially in the polluted troposphere. Its photolysis after sunrise is an important source of hydroxyl free radicals (OH). Measurements...

2009/9/2
We investigated the influence of meteorological variability on the interannual variation of springtime boundary layer ozone over Japan during 1981–2005 by multiyear simulations with the Models-3 Commu...
Modelling multi-phase halogen chemistry in the remote marine boundary layer: investigation of the influence of aerosol size resolution on predicted gas- and condensed-phase chemistry
Modelling multi-phase halogen chemistry remote marine boundary layer aerosol size resolution
2009/7/22
A coupled box model of photochemistry and aerosol microphysics which explicitly accounts for size-dependent chemical properties of the condensed-phase has been developed to simulate the multi-phase ch...
Ozone in the boundary layer air over the Arctic Ocean: measurements during the TARA transpolar drift 2006–2008
Ozone boundary layer air Arctic Ocean measurements TARA transpolar drift
2009/7/22
A full year of measurements of surface ozone over the Arctic Ocean far removed from land is presented (81° N–88° N latitude). The data were obtained during the drift of the French schooner TARA betwee...
Exploring atmospheric boundary layer characteristics in a severe SO2 episode in the north-eastern Adriatic
atmospheric boundary layer severe SO2 episode north-eastern Adriatic
2009/7/15
Stable atmospheric conditions are often connected with the occurrence of high pollution episodes especially in urban or industrial areas. In this work we investigate a severe SO2 episode observed on 3...
