Measurement of rotational temperature at Kolhapur, India

Abstract

Abstract. Measurements of the hydroxyl rotational temperature for the (8,3) Meinel band have been reported from the observations of the ratio of the relative intensities of P 1 (2) and P 1 (4) lines of the OH(8,3) band at Kolhapur

Daytime upper mesospheric energetics over a tropical station, Trivandrum (8.5°N, 77°E): An investigation using the multiwavelength dayglow photometry

“…Most of the measurements on the mesospheric temperature in the past have come from the rocket and ground based optical experiments. A range of ground based instruments like Photometers, Spectrometers, and Lidars provided systematic measurements on the temperature and its temporal variabilities over a number of locations over the globe [von Zahn et al, 1996;Sridharan et al, 1999;Taylor et al, 2001;She et al, 2003;French and Burns, 2004;Mukherjee and Parihar, 2004].…”

“…Since, most of the studies on the mesopause region had been performed during the night (for example, Mukherjee and Parihar [2004]), the aforesaid studies need special attention. Such measurements would perhaps help us to characterize the influence of solar radiation and dynamical factors on the mesosphere in a much effective manner.…”

A comparison of ground-based hydroxyl airglow temperatures with SABER/TIMED measurements over 23° N, India

“…Nightglow observations of OH Meinel band have been widely used to obtain the temperature information of the upper mesospheric region near 87 ± 4 km (Meriwether, 1975;Offermann and Gerndt, 1990;Scheer and Reisin, 1990;Takahashi et al, 1994;Greet et al, 1998;French et al, 2000;Bittner et al, 2002;Burns et al, 2003;Mukherjee and Parihar, 2004;Offermann et al, 2010;Parihar et al, 2013). Several space-borne instruments like the Microwave Limb Sounder (MLS) on the Aura satellite; Atmospheric Chemistry Experiment -Fourier Transform Spectrometer (ACE-FTS) on SciSat-1; Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) and SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric Chartography) on Environmental Satellite (ENVISAT); Solar Occultation for Ice Experiment (SOFIE) on the AIM satellite; Optical, Spectroscopic, and Infrared Remote Imaging System (ORISIS) on the Odin satellite; the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) satellite instrument, and Sounding of the Atmosphere by Broadband Emission of Radiation (SABER) on-board the TIMED mission satellite have also contributed immensely to our knowledge of the temperature field of the MLT region (von Savigny et al, 2004;Scheer et al, 2006;Xu et al, 2007;Mulligan and Lowe, 2008;French and Mulligan, 2010;Sheese et al, 2011;García-Comas et al, 2012, 2014and references cited therein).…”
