Understanding the variability of nightside temperatures, NO UV and O2 IR nightglow emissions in the Venus upper atmosphere
[1] Venus Express (VEX) has been monitoring key nightglow emissions and thermal features (O2 IR nightglow, NO UV nightglow, and nightside temperatures) which contribute to a comprehensive understanding of the global dynamics and circulation patterns above ∼90 km. The nightglow emissions serve as effective tracers of Venus’ middle and upper atmosphere global wind system due to their variable pea...
متن کاملOBSERVATION OF 3 μm HYDRATION FEATURE ON MARS FROM OMEGA-MEx DATA
Introduction: The OMEGA investigation, on board the ESA Mars Express mission, is to map Mars’ surface at a 0.3to 5-kilometer resolution using visible-infrared hyperspectral reflectance imagery. After numerous results on Mars surface diversity using the C channel (1.0 to 2.5 μm) [1], this paper reports a systematic reduction of the OMEGA data in the L channel (spectral range 2.5 to 5.1 μm). This...
متن کاملMaps of the O 2 ( 1 Δ ) Emission During the Mars Pre - Aphelion Season
Introduction . Ozone and water are key species for understanding the stability and evolution of Mars’ atmosphere; they are closely linked (along with CO, H, OH, and O) through photochemistry [1-6]. Measurements of ozone on Mars have been made by both ground based telescopes [7-13] and spacecraft [14-17]. Some of these measured the total column density of ozone [8, 11, 14] while others measured ...
متن کاملRadio occultation measurements and MGCM simulations of Kelvin waves on Mars
We have derived new results concerning thermal tides on Mars from a combination of radio occultation measurements and numerical simulations by a Mars General Circulation Model (MGCM). This investigation exploits a set of concurrent observations by Mars Express (MEX) and Mars Global Surveyor (MGS) in mid-2004, when the season on Mars was midspring in the northern hemisphere. The MEX occultations...
متن کاملA Comparative Study of Omega RSM and RNG k–Epsilon Model for the Numerical Simulation of a Hydrocyclone
The design and optimization of hydrocyclones using CFD techniques are gaining popularity and the key to a successful simulation lies with the accurate description of the high turbulent swirling behavior of the flow. This paper presents a detailed co...
