Amid the season known for transforming Nebraska into an outdoor ice rink, a University of Nebraska-Lincoln-led research team has predicted a new molecular form of the slippery stuff that even Mother N...
Long's equation describes two dimensional stratified atmospheric flow over terrain. Its solutions using regular first order perturbations and linear approximation were investigated analytically and nu...

Small scale density variations of electrons and charged particles in the vicinity of polar mesosphere summer echoes
variations of electrons charged particles polar mesosphere summer echoes

Atmospheric aerosols play significant roles in climatic related phenomena. Size, density and shape of particles affect their fluid-dynamic parameters which in turn dictate their transport and lifecycl...
Correlation between traffic density and particle size distribution in a street canyon and the dependence on wind direction
traffic density particle size distribution street canyon wind direction
2009/1/15
Combustion of fossil fuel in gasoline and diesel powered vehicles is a major source of aerosol particles in a city. In a street canyon, the number concentration of particles smaller than 300 nm in di...
Effects of column density on I2 spectroscopy and a determination of I2 absorption cross section at 500 nm
column density I2 spectroscopy I2 absorption cross section
2009/1/9
The use of ro-vibronic spectra of I2 in the region of 543 nm to 578 nm as reference spectra for atmospheric Differential Optical Absorption Spectroscopy is studied. It is shown that the retrieval of a...
Comparison of high-latitude line-of-sight ozone column density with derived ozone fields and the effects of horizontal inhomogeneity
high-latitude line-of-sight ozone column density derived ozone fields effects of horizontal inhomogeneity
2009/1/8
Extensive ozone measurements were made during the second SAGE III Ozone Loss and Validation Experiment (SOLVE II). We compare high-latitude line-of-sight (LOS) slant column ozone measurements from the...
Mode resolved density of atmospheric aerosol particles
density atmospheric aerosol particles
2008/11/19
In this study, we investigate the mode resolved density of ultrafine atmospheric particles measured in boreal forest environment. The method used here enables us to find the distinct density informati...
Influence of clouds on the spectral actinic flux density in the lower troposphere (INSPECTRO): overview of the field campaigns
