Revealing a High Water Abundance in the Upper Mesosphere of Mars with ACS onboard TGO

This dateset represents results from the middle infrared spectrometer of the Atmospheric Chemistry Suite (ACS MIR) operating on board ExoMars Trace Gas Orbiter in regime of solar occultation. The instrument measures altitude profiles of water vapor content in the atmosphere of Mars. Here we present profiles of H2O volume mixing ratio (VMR) measured during the second halves of Martian Years (MY) 34 and 35. Those seasonal intervals correspond to ACS MIR observations from May 2018 to March 2019 and from April 2020 to January 2021. The selected dataset comprises 187 occultation sessions in the Northern Hemisphere and 156 sessions in the Southern Hemisphere, encompassing seasonal periods from LS 180° to 355° in MY34 and from LS 185° to 356° in MY35.

The dataset analysis is presented in the article of Belyaev et al. (2021) "Revealing a High Water Abundance in the Upper Mesosphere of Mars with ACS onboard TGO" published in Geophysical Research Letters (doi:10.1029/2021GL093411) with open access at ESSOAr: https://doi.org/10.1002/essoar.10506560.2
