“…It is a result of the solar ultraviolet (UV) photodissociation of ozone in the Martian atmosphere and can be used as a good tracer for atmospheric ozone abundance. The photodissociation process of ozone of O 2 (a 1 ∆ g ) molecules can be shown in Equation (1). The O 2 (a 1 ∆ g ) molecules can be quenched by collision with CO 2 , which is widely present in the Martian atmosphere, as shown in Equation (2).…”

“…The Mars atmospheric global remote sensing measurement is an important objective of Mars exploration. As the key parameter of Mars atmospheric dynamics, Mars' wind field and temperature field play an important role in understanding the basic dynamic balance of the atmosphere, the basic transport process of Mars substances (such as dust, aerosols, and chemical components), the Mars ionospheric electrodynamics (Mars thermosphere-ionosphere coupling), and ensuring the safe landing of future unmanned spacecraft [1][2][3]. Currently, there is a lack of effective means for globally detecting the low-level atmospheric wind field on Mars, which seriously hinders the research of Mars atmospheric circulation and energy transport.…”

“…Currently, there are at least two proposed instrument schemes that are in the proposal stage for imaging Mars' atmospheric wind fields, namely, the microwave and submillimeterwave limb sounder [2,22,23] and the Doppler Michelson atmospheric dynamics interferometer (DYNAMO) [1,3]. Both of these instruments measure the Doppler shift of the absorption or the emission spectra of atmospheric molecules on Mars to obtain wind velocity information.…”

“…The microwave and submillimeter-wave limb sounder is less affected by dust, ice clouds, and aerosols in the Martian atmosphere due to its longer wavelength. However, its wind velocity measurement accuracy is relatively low, with a typical accuracy of 15 m/s, and its vertical resolution is also limited, which restricts the fine description of vertical dynamic processes in the Martian atmosphere [1]. DYNAMO is a conceptual instrument proposed by W.E.…”

“…Ward et al [3] in 2002 for passive measuring Martian atmospheric information such as wind fields, temperature, and composition, among others. In 2021, Tao YU et al [1] constructed a forward model for the DYNAMO instrument consisting of an orbit submodel, an atmospheric background field submodel, and an instrument submodel. A very detailed study was conducted on the principles of Martian atmospheric wind field monitoring, particularly the forward and inverse modeling, making it a valuable reference.…”

The Mars Atmospheric Wind Imaging Interferometer offers several advantages, notably its high throughput, enabling the acquisition of precise and high vertical resolution data on the temperature and wind fields in the Martian atmosphere. Considering the current absence of such an Interferometer, this paper introduces a novel Mars wind field imaging interferometer. In analyzing the photochemical model of O2 (a1Δg) 1.27 μm molecular airglow radiation in the Martian atmosphere and considering the impact of instrument signal-to-noise ratio (SNR), we have chosen an optical path difference (OPD) of 8.6 cm for the interferometer. The all-solid-state polarized wind imaging interferometer is miniaturized by incorporating two arm glasses as the compensation medium in its construction, achieving the effects of field-widening and temperature compensation. Additionally, an F-P Etalon is designed to selectively filter the desired three spectral lines of O2 dayglow, and its effect is evaluated through simulations. The accuracy of the proposed compact Mars polarized wind imaging interferometer for detecting Mars’ wind field and temperature field has been validated through rigorous theoretical derivation and comprehensive computer simulations. The interferometer boasts several advantages, including its compact and small size, static stability, minimal stray light, and absence of moving parts. It establishes the theoretical, technological, and instrumental engineering foundations for future simultaneous static measurement of Martian global atmospheric wind fields, temperature fields, and ozone concentrations from spacecraft, thereby significantly contributing to the dataset for investigating Martian atmospheric dynamics.
