[1] Calculations of radiative transfer in CO2-rich atmospheres are central to modeling the early climate of Earth and Mars. Line-by-line radiative transfer models are the most accurate means of carrying out such calculations and provide the basis for all other radiative transfer approaches. We examine the sensitivity of line-by-line results to three parameterizations of line and continuum absor...

When comet C/2013 A1 (Siding Spring) passed nearbyMars in 2014, it offered an unprecedented opportunity to observe the interaction between the dust tail of the comet and the atmosphere of Mars. Here I provide an overview of a recent series of four articles reporting observations from three satellites fortuitously orbiting Mars at the appropriate time (MAVEN, MEX, and MRO). These observations re...

NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission records several high-frequency (>0.5 Hz) dispersive seismic signals on Mars. These are due to the acoustic-to-seismic coupling of infrasound generated by entry impact meteorites. This dispersion property is propagating in a structured atmosphere, we refer this as guided infrasound. We propose ...

Introduction: It has long been realized that the daytime convective boundary layer on Mars is generally much deeper than that on Earth [1]. This is fundamentally the consequence of the low density of the Martian atmosphere, coupled with the fact that the solar thermal forcing of the surface is not that much weaker than on the Earth. Simple consideration of these factors leads to a basic recogni...

Abstract This study provides a comprehensive description of the deposition meteor-ablated metals in upper atmosphere Mars, accounting for temporal, vertical, latitudinal, and seasonal distribution. For this purpose, Leeds Chemical Ablation Model is combined with meteoroid input function to characterize size velocity distributions three distinctive populations around Mars—the Jupiter-family come...

The accurate estimation of suspended sediments (SSs) carries significance in determining the volume dam storage, river carrying capacity, pollution susceptibility, soil erosion potential, aquatic ecological impacts, and design operation hydraulic structures. presented study proposes a new method for accurately estimating daily SSs using antecedent discharge sediment information. novel is develo...
