• OI 630.0 nm post-sunset emission enhancement as an effect of tidal activity...

  The OI 630.0 nm airglow emission variability provides salient information on the dynamical changes taking place in the upper atmosphere at around 250 km. The emission rates vary...

• The chemistry of mercury in the stratosphere

  Mercury, a global contaminant, enters the stratosphere through convective uplift, but its chemical cycling in the stratosphere is unknown. We report the first model of...

• Turbulence comes in bursts in stably stratified flows

  There is a clear distinction between simple laminar and complex turbulent fluids; however, in some cases, as for the nocturnal planetary boundary layer, a stable and well-...

• Marine cloud brightening

  The idea behind the marine cloud-brightening (MCB) geoengineering technique is that seeding marine stratocumulus clouds with copious quantities of roughly monodisperse sub-...

• Adapting the MPAS dynamical core for applications extending into the thermosphere

  To extend the nonhydrostatic global Model for Prediction Across Scales (MPAS) for deep-atmosphere (geospace) applications, we have modified the model equations and numerics to...

• Is Proxima Centauri b habitable? A study of atmospheric loss

  We address the important question of whether the newly discovered exoplanet, Proxima Centauri b (PCb), is capable of retaining an atmosphere over long periods of time. This is...
