Heating of the auroral ionosphere by traveling ionospheric disturbances initiated by atmospheric gravity waves
ionospheric dynamics plasma physics auroral phenomena
2015/8/28
In the presence of perturbations of the thermospheric auroral region produced by traveling ionospheric disturbances during the propagation of atmospheric gravity waves, an analytical expression of the...
Chemical evolution of secondary organic aerosol from OH-initiated heterogeneous oxidation
Chemical evolution secondary organic aerosol OH-initiated heterogeneous oxidation
2010/8/13
The heterogeneous oxidation of laboratory Secondary Organic Aerosol (SOA) particles by OH radicals was investigated. SOA particles, produced by reaction of α-pinene and O3, were exposed to OH radicals...
Tropospheric photooxidation of CF3CH2CHO and CF3(CH2)2CHO initiated by Cl atoms and OH radicals
Tropospheric photooxidation CF3CH2CHO Cl atoms OH radicals
2010/2/21
The absolute rate coefficients for the tropospheric reactions of chlorine (Cl) atoms and hydroxyl (OH) radicals with CF3CH2CHO and CF3(CH2)2CHO were measured as a function of temperature (263–371 K) a...
Comment on evidence for surface-initiated homogeneous nucleation
surface-initiated homogeneous nucleation
2009/3/11
We investigate theoretical, laboratory, and atmospheric evidence for a recently proposed hypothesis: homogeneous ice nucleation initiates at the surface, not in the volume, of supercooled water drops....
Atmospheric chemistry of trans-CF3CH=CHF: products and mechanisms of hydroxyl radical and chlorine atom initiated oxidation
trans-CF3CH=CHF hydroxyl radical chlorine atom oxidation
2008/11/11
Smog chamber/FTIR techniques were used to study the products and mechanisms of OH radical and Cl atom initiated oxidation of trans-CF3CH=CHF in 700 Torr of N2/O2 diluent at 295±1 K. Hydroxyl radical i...
