In the rainy season in Rondônia, convection in low-level westerly flows with low aerosol content resembles oceanic convection with precipitation from warm rain processes and little electrificati...
The heterogeneous reaction of hydroxyl radicals with sub-micron squalane particles: a model system for understanding the oxidative aging of ambient aerosols
heterogeneous reaction hydroxyl radicals sub-micron squalane particles ambient aerosols
2009/6/2
The heterogeneous reaction of OH radicals with sub-micron squalane particles, in the presence of O2, is used as a model system to explore the fundamental chemical mechanisms that control the oxidative...
Polar mesosphere summer echoes（PMSE）：Review of observations and current understanding
Polar mesosphere summer echoes PMSE current understanding
2009/3/10
Polar mesosphere summer echoes (PMSE) are very strong radar echoes primarily studied in the VHF wavelength range from altitudes close to the polar summer mesopause. Radar waves are scattered at irregu...

Observations of gas-phase HNO3 and N2O in the polar stratosphere from the Michelson Interferometer for Passive Atmospheric Sounding aboard the ENVISAT satellite (MIPAS-E) were made during the cold Arc...
Among the major factors controlling ozone loss in the polar vortices in winter/spring is the kinetics of the ClO dimer catalytic cycle. Here, we propose a strategy to test and improve our understandin...
On the variability of the Ring effect in the near ultraviolet: understanding the role of aerosols and multiple scattering
ultraviolet aerosols multiple scattering
2008/12/1
The "filling-in" (FI) of Fraunhofer lines, often referred to as the Ring effect, was examined using measurements of near ultraviolet sunlight scattered from the zenith sky above Boulder, Colorado duri...
