The homopause marks the transition in a planetary atmosphere from turbulent mixing, which maintains a well-mixed composition, to molecular diffusion, which causes the diffusive separation of chemical species, impacting how these are distributed in the upper atmosphere and potentially escape to space. …

Observations of ultraviolet dayglow provide valuable insights into the composition, energetics, and dynamics of planetary atmospheres. The Emirates Mars Ultraviolet Spectrometer (EMUS) onboard the Emirates Mars Mission (EMM) uniquely captures extreme ultraviolet (EUV) and far ultraviolet (FUV) emissions from Mars’ upper atmosphere. …

Introduction and GoalThe upper atmosphere of Mars, spanning the mesosphere (60–120 km) and the thermosphere up to the exobase (180–230 km), remains one of the least characterized regions of the planet [1]. Its structure is shaped by solar forcing, upward‑propagating waves, and …

Abstract F 10.7 , Mg II, and F 30 are widely used proxies for variability in solar Extreme UltraViolet (EUV, 5–120 nm) irradiance. An alternative proxy for solar EUV variability is Q EUV , an indirect measure of total solar EUV irradiance, …

Abstract Using NASA's Global‐scale Observations of the Limb and Disk (GOLD)'s Dark Limb Mode (DLM) observations, we provide a multi‐year characterization of nighttime Equatorial Ionization Anomaly (EIA) morphology and variability. From geostationary orbit, GOLD measures OI 135.6 nm limb radiance at ∼33°E …

Abstract We report the signature of solar forcing in the thermosphere using daytime temperature profiles from the Michelson Interferometer for Global High‐resolution Thermospheric Imaging (MIGHTI) instrument on NASA's Ionospheric Connection (ICON) Explorer mission. We compare temperatures from 90 to 133 km altitude …

F10.7, Mg II, and F30 are the current, standard measures of variability in solar Extreme UltraViolet (EUV) irradiance. An alternative proxy of solar variability is QEUV, an indirect measure of total solar EUV irradiance, which has been retrieved using observations of Earth’s …

BACKGROUND: Despite available screening tools for eating disorders (EDs), the accuracy and suitability of these in identifying binge eating disorder (BED) and bulimia nervosa (BN) in a primary care setting are undetermined, despite BED and BN being the most common EDs. AIM: …

The upper atmosphere of Mars, including the mesosphere (60-120 km) and thermosphere (120 up to the exobase, around 180-230 km), is no doubt the less explored region of the red planet. Two recent and on-going missions to Mars are investigating these altitudes …

The study of the coupling between the lower and the upper atmosphere has been hindered by the lack of continuous temperature measurements covering the whole atmosphere from the surface to the exobase. Thus, a large fraction of our knowledge on the topic …

Introduction: The homopause defines the boundary between two distinct regions of the atmosphere: the homosphere and the heterosphere. In the homosphere, located below the homopause, strong turbulent mixing causes atmospheric gases to vary vertically according to a common scale height, determined by …
