Atmospheric photochemistry via vibrational overtone absorption

Article Abstract:

Pernitric acid is an important source of atmospheric HO(sub x) at high solar zenith angles via direct solar excitation of the lower overtones of the OH vibration. Overtone-driven dissociation seems to be an important loss process for this molecule in the free troposphere and may be so in the Antarctic boundary layer and snowpack.

Photolysis of the atmospheric ozone in the ultraviolet region

Article Abstract:

Studies on the photodissociation processes in the ultraviolet (UV) photolysis of ozone are reviewed. The atmospheric roles of the electronically, vibrationally, and/or translationally excited species which are produced by the UV photodissociation of ozone are presented.

Large-scale atmospheric dynamics for atmospheric chemists

Article Abstract:

Atmospheric dynamics affects atmosphere composition through both temperature and transport and are nonlinearly coupled. The important distinctions, both chemically and dynamically between the troposphere and the middle atmosphere are stated.
