Submitted to The Planetary Science Journal.</p> <p>Abstract:</p> <p>"Cloud cover at the planetary limb of water-rich Earth-like planets is likely to weaken chemical<br> signatures in transmission spectra, impeding attempts to characterize these atmospheres. However,<br> based on observations of Earth and solar system worlds, exoplanets with atmospheres should have both<br> short-term weather and long-term climate variability, implying that cloud cover may be less during<br> some observing periods. We identify and describe a mechanism driving periodic clear sky events at<br> the terminators in simulations of tidally locked Earth-like planets. A feedback between dayside cloud<br> radiative effects, incoming stellar radiation and heating, and the dynamical state of the atmosphere,<br> especially the zonal wavenumber-1 Rossby wave identified in past work on tidally locked planets, leads<br> to oscillations in Rossby wave phase speeds and in the position of Rossby gyres and results in advection<br> of clouds to or away from the planet’s eastern terminator. We study this oscillation in simulations of<br> Proxima Centauri b, TRAPPIST 1-e, and rapidly rotating versions of these worlds located at the inner<br> edge of their stars’ habitable zones. We simulate time series of the transit depths of the 1.4 μm water<br> feature and 2.7 μm carbon dioxide feature. The impact of atmospheric variability on the transmission<br> spectra is sensitive to the structure of the dayside cloud cover and the location of the Rossby gyres,<br> but none of our simulations have variability significant enough to be detectable with current methods."</p>
3D simulations of TRAPPIST-1e with varying CO2, CH4 and haze profiles [dataset]
<p>Dataset of 3D simulations of TRAPPIST-1e with varying CO2, CH4 and haze profiles</p><p> </p><p>Using a 3D General Circulation Model, the Unified Model, we present results from simulations of a tidally locked TRAPPIST-1e with varying CO2 and CH4 gas concentrations, and their corresponding prescribed spherical haze profiles. Our results show that the presence of CO2 leads to a warmer atmosphere globally due to its greenhouse effect, with the increase of surface temperature on the day side surface up to ∼14.1 K, and on the night side up to ∼21.2 K. The presence of CH4 can lead to a peak in the change of surface temperature on the day side due to the balance of tropospheric warming and stratospheric cooling. A thin layer of haze, formed when CH4/CO2 = 0.1, leads to a day side warming of ∼4.9 K due to a change in the water vapour and cloud distribution. The haze reaches an optical threshold thickness when CH4/CO2 ∼0.4 beyond which the day side mean surface temperature does not vary much. The planet is more favourable to habitability (surface temperature above 273.15 K) when pCO2 is high, pCH4 is low and the haze layer is thin. The effect of CO2, CH4 and haze on the day side is similar to that for a rapidly-rotating planet. On the contrary, their effect on the night side depends on the wind structure and the wind speed in the simulation.</p>
