Global Model of Atmospheric Chlorate on Earth
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.Abstract Naturally occurring chlorate (ClO3−) has been observed on Earth and potentially plays important roles in hydrology and mineralogy on Mars. However, natural sources of chlorate are uncertain. Here, we quantify the importance of atmospheric sources of chlorate.

Ares: A Mars model retrieval framework for ExoMars Trace Gas Orbiter NOMAD solar occultation measurements [PDF]
arXiv, 2020 Ares is an extension of the TauREx 3 retrieval framework for the Martian atmosphere. Ares is a collection of new atmospheric parameters and forward models, designed for the European Space Agency's (ESA) Trace Gas Orbiter (TGO) Nadir and Occultation for MArs Discovery (NOMAD) instrument, Solar Occultation (SO) channel. Ares provides unique insights into

Energy dependence of x‐ray beam size produced by polycapillary x‐ray optics
X-Ray Spectrometry, Volume 54, Issue 2, Page 203-213, March/April 2025.Abstract In this work, we studied the x‐ray energy dependence of x‐ray beam diameter focused by polycapillary optics. A quantitative beam diameter–energy relation enables more accurate estimation of the element‐specific interrogation area of a sample using the compositional maps produced by a micro‐XRF system.

Modeling the variations of Dose Rate measured by RAD during the first MSL Martian year: 2012-2014 [PDF]
, 2015 The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) rover Curiosity, measures the {energy spectra} of both energetic charged and neutral particles along with the radiation dose rate at the surface of Mars. With these first-ever measurements on the Martian surface, RAD observed several effects influencing the galactic ...

Measurements of Forbush decreases at Mars: both by MSL on ground and by MAVEN in orbit
, 2017 The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) Curiosity rover, has been measuring ground level particle fluxes along with the radiation dose rate at the surface of Mars since August 2012. Similar to neutron monitors at

Journal of Geophysical Research: Planets, Volume 130, Issue 3, March 2025.Abstract The objective of this study is to examine the climatology of the residual mean circulation, and the roles of wave forcings by both resolved waves (RWs) and unresolved waves (UWs). The analysis is performed using data from the Ensemble Mars Atmosphere Reanalysis System (EMARS) over four Mars Years without global dust storms, based on the ...
