Full-text available
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere. The location and timing of its detection on Mars were restricted to a winter season at the north pole. We...
Article
Observations of vibrationally excited hydroxyl (OH*) emissions are widely used to obtain information about the dynamics and composition of the atmosphere. We present some analytical approximations for the characteristics of the hydroxyl layer in the Martian atmosphere such as OH* concentration at the maximum and height of the maximum, as well as re...

Observations of excited hydroxyl (OH*) emissions are broadly used for inferring information about atmospheric dynamics and composition. We present several analytical approximations for characterizing the excited hydroxyl layer in the Martian atmosphere. They include the OH* number density at the maximum and the height of the peak, along with the re...

Introduction: Airglow emissions of OH * in the Earth meso-pause region are used for obtaining information about gravity wave, planetary wave and tidal parameters , chemical distributions (O and H), and temperature (trends, solar cycle effects, and annual variations). Recently, hydroxyl emissions were found in the Martian atmosphere (Clancy et al.,...

Plain Language Summary Transport of water to the Martian upper atmosphere with subsequent photodissociation and escape of hydrogen into space occurs near perihelion and amplifies during global dust storms. One explanation is the so‐called water “pump” due to the seasonally varying global meridional circulation. Forcing by atmospheric gravity waves...

Simulations with the Max Planck Institute Martian general circulation model for Martian years 28 and 34 reveal details of the water "pump" mechanism and the role of gravity wave (GW) forcing. Water is advected to the upper atmosphere mainly by upward branches of the meridional circulation: in low latitudes during equinoxes and over the south pole d...
Conference Paper
Accurate knowledge about the properties of the atmosphere of Mars is highly demanded in its climate simulation. To contribute to the Martian atmosphere investigation , authors propose the concept of a multichannel laser heterodyne spectroradiometer (MLHS) based on a CubeSat formfactor. The instrument will measure: mixing ratio of CO2, H2O, their ve...
Article
Full-text available
We present results of simulations with the Max Planck Institute Martian general circulation model implementing a hydrological cycle scheme. The simulations reveal a seasonal water “pump” mechanism responsible for the upward transport of water vapor. This mechanism occurs in high latitudes above 60° of the southern hemisphere at perihelion, when the...

We present results of simulations with the Max Planck Institute general circulation model (MPI-MGCM) implementing a hydrological cycle scheme. The simulations reveal a seasonal water "pump" mechanism responsible for the upward transport of water vapor. This mechanism occurs in high latitudes above 60$^\circ$ of the southern hemisphere at perihelion...

We present a new implementation of the hydrological cycle scheme into a general circulation model of the Martian atmosphere. The model includes a semi-Lagrangian transport scheme for water vapor and ice, and accounts for microphysics of phase transitions between them. The hydrological scheme includes processes of saturation, nucleation, particle gr...

Within the numerical general-circulation model of the Martian atmosphere MAOAM (Martian Atmosphere: Observation and Modeling), we have developed the water cycle block, which is an essential component of modern general circulation models of the Martian atmosphere. The MAOAM model has a spectral dynamic core and successfully predicts the temperature...
