ExoMars-2022 Mission ODS Instrument: Modeling and Ground Field Measurements
Abstract—
The paper presents the results of modeling and ground-based field measurements of the ODS (Optical Depth Sensor) instrument, designed to study aerosol in the Martian atmosphere through daily measurements of illumination on the planet’s surface. The device was part of the meteo suite located on the landing platform of the ExoMars-2022 mission. The article presents the structure of the instrument, its optical design and the spectral characteristics of two channels. The main elements of the model for calculating the radiation flux measured by the instrument are described depending on the structure of the atmosphere, the aerosol suspended in it, and the daily motion of the Sun. The calculations were carried out in the approximation of a pseudospherical atmosphere, taking into account the multiple scattering of radiation. Using the created model adapted for the Earth’s atmosphere, the ODS signal was simulated for two series of ground-based field measurements at different latitudes. The measured daily dependences in comparison with the simulation results make it possible to determine the optical depth with an accuracy of 0.1.
期刊介绍：
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
