Global photochemical model CHARM-DE of the Earth’s atmosphere for altitudes 0-130 km

Title : Global photochemical model CHARM-DE of the Earth’s atmosphere for altitudes 0-130 km

Abstract:

A numerical photochemical global non-stationary model CHARM-DE (Chemical Atmospheric Research Model with D and E regions). The model is a development of the basic version CHARM /1/, which describes the chemistry of neutral constituents. The new model describes the interaction of 127 neutral (ozone and other constituents) and charged chemical species (including electron concentration), participating in 250 photochemical reactions. The model covers the altitude range from the Earth’s surface up to 130 km, which includes the D and E regions of the ionosphere. Ionization is caused by galactic cosmic rays and solar ultraviolet radiation at the wavelength of the solar Lyman-alpha emission. Spatial resolution: 10° in latitude, 5° in longitude. Vertical resolution is 1 km. Time step is 10 minutes. Results of calculations for quiet (undisturbed) conditions are presented.

Biography:

Alexei Alexandrovich Krivolutsky, born in 1946, graduated from the Faculty of Physics, Department of Atmospheric Physics, at Moscow State University in 1971. After serving in the Soviet Army, he joined the Central Aerological Observatory in 1973, under the Russian Federal Service of Hydrometeorology, located in Dolgoprudny, Moscow Region. Since 1999, he has served as the Head of the Laboratory for Atmospheric Chemistry and Dynamics, where his research focuses on the development and application of three-dimensional numerical models for global atmospheric chemistry and dynamics.
