Journal ArticleDOI
Description and climatology of a new general circulation model of the Martian atmosphere
Paul Hartogh,Alexander S. Medvedev,Takeshi Kuroda,Ryu Saito,Geronimo L. Villanueva,Artem G. Feofilov,Alexander A. Kutepov,Uwe Berger +7 more
TL;DR: In this paper, a grid point global general circulation model (GCM) for the Martian atmosphere with the vertical domain extending from the surface into the lower thermosphere (around 130 km) is presented.
Journal ArticleDOI
Solution of the non-LTE problem for molecular gas in planetary atmospheres: superiority of accelerated lambda iteration
TL;DR: In this paper, a general formulation of the multi-level rotation-vibrational non-LTE problem for a mixture of radiating molecular gases in a planetary atmosphere, treating explicitly the coupling of molecular energy levels by collisionally induced energy transfer processes and by band overlap, is given.
Journal ArticleDOI
SABER temperature observations in the summer polar mesosphere and lower thermosphere: Importance of accounting for the CO2ν2 quanta V–V exchange
Alexander A. Kutepov,Alexander A. Kutepov,Alexander A. Kutepov,Artem G. Feofilov,B. T. Marshall,Larry L. Gordley,W. Dean Pesnell,Richard A. Goldberg,James M. Russell +8 more
TL;DR: In this article, the authors validate the non-LTE model applied for operational temperature retrievals from the SABER 15 μm limb radiance observations for these extreme conditions and demonstrate that accounting for the redistribution of ν2 quanta among various CO2 isotopes shifts the retrieved summer 2002 polar mesopause altitude upwards by 2 to 4 km.
Journal ArticleDOI
The vertical and horizontal distribution of CO2 densities in the upper mesosphere and lower thermosphere as measured by CRISTA
Martin Kaufmann,O. A. Gusev,K.U. Grossmann,Raymond G. Roble,Maura E. Hagan,C. Hartsough,Alexander A. Kutepov +6 more
TL;DR: In this article, a detailed sensitivity study of retrieved CO2 number densities was carried out, where the O(1D) excitation mechanism and model parameters constitute the most important uncertainties.
Journal ArticleDOI
Simultaneous retrieval of T(p) and CO2 VMR from two-channel non-LTE limb radiances and application to daytime SABER/TIMED measurements
Ladislav Rezac,Alexander A. Kutepov,Alexander A. Kutepov,James M. Russell,Artem G. Feofilov,Jia Yue,Richard A. Goldberg +6 more
TL;DR: In this article, a self-consistent simultaneous retrieval of temperature/pressure, Tk(p), and CO2 volume mixing ratio (VMR) from the broadband infrared limb measurements in the 15 and 4.3 μ m channels is presented.
