Title: | Temperature estimation from hydroxyl airglow emission in the Venus night side mesosphere | Authors: | MIGLIORINI, Alessandra Snels, M. Gérard, J. -C. Soret, L. PICCIONI, GIUSEPPE Drossart, P. |
Issue Date: | 2018 | Journal: | ICARUS | Number: | 300 | First Page: | 386 | Abstract: | The temperature of the night side of Venus at about 95 km has been determined by using spectral features of the hydroxyl airglow emission around 3 μm, recorded from July 2006 to July 2008 by VIRTIS onboard Venus Express. The retrieved temperatures vary from 145.5 to about 198.1 K with an average value of 176.3 ± 14.3 K and are in good agreement with previous ground-based and space observations. The variability with respect to latitude and local time has been studied, showing a minimum of temperature at equatorial latitudes, while temperature values increase toward mid latitudes with a local maximum at about 35°N. The present work provides an independent contribution to the temperature estimation in the transition region between the Venus upper mesosphere and the lower thermosphere, by using the OH emission as a thermometer, following the technique previously applied to the high-resolution O<SUB>2</SUB>(a<SUP>1</SUP>∆<SUB>g</SUB>) airglow emissions observed from ground. | URI: | http://hdl.handle.net/20.500.12386/27504 | URL: | https://www.sciencedirect.com/science/article/pii/S0019103517303937?via%3Dihub | ISSN: | 0019-1035 | DOI: | 10.1016/j.icarus.2017.09.026 | Bibcode ADS: | 2018Icar..300..386M | Fulltext: | reserved |
