Dr Lakshmi Narayanan, Assistant Professor, Environmental Studies, SIAS has co-authored an article titled Study of rotational temperatures with a multi-wavelength photometer from the Indian equatorial station Tirunelveli published recently in the Journal of Atmospheric and Solar-Terrestrial Physics. This is a validation paper of an instrument the team developed at the Indian Institute of Geomagnetism. In this paper, the authors show that they could successfully measure temperatures from the upper mesosphere around 87 km. The results are validated through comparison with NASA’s SABER/TIMED satellite observations and other ground based airglow imaging observations.
