Abstract

Measurements made by MERTIS (MErcury Radiometer and Thermal Infrared Spectrometer) during the BepiColombo mission's first and second close flybys of Venus in October 2020 (FB1) and August 2021 (FB2) have provided a new and solid data base for the study of the planet's mesosphere at near equatorial latitudes. During the two FBs, the Pushbroom IR grating spectrometer (TIS) of the MERTIS instrument recorded a large number of spectra of planetary radiation from Venus in the 7-14 μm spectral range (715 - 1430 cm^-1) for the first time since the Venera-15 Fourier spectrometer experiment FS-1/4 (PMV) in 1983. The MERTIS instrument was designed to study the hot surface of Mercury. Despite the much lower intensity of radiation from the Venusian mesosphere, it was able to demonstrate its suitability for studying the mesospheric temperature profile and various aspects of the mesospheric composition. In this paper, we demonstrate the capability of the MERTIS technology for the study of the Venusian atmosphere. We report on our technical and calibration approach and the main results of the two flybys. Our results on atmospheric temperature profiles and cloud parameters of the upper troposphere and mesosphere (60-75 km) of Venus are presented. We draw conclusions on the applicability and prospects of the developed technology for future targeted explorations of the Venusian mesosphere.
