Atmospheric composition, chemistry, and clouds [PDF]

, 2007
Venus’ atmosphere has a rich chemistry involving interactions among sulfur, chlorine, nitrogen, hydrogen, and oxygen radicals. The chemical regimes in the atmosphere range from ion-neutral reactions in the ionosphere to photochemistry in the middle atmosphere to thermal equilibrium chemistry and surface-atmosphere reactions in the lower atmosphere.

Resolved Convection in Hydrogen-rich Atmospheres

The Planetary Science Journal
In hydrogen-rich atmospheres with low mean molecular weight (MMW), an air parcel containing a higher-molecular-weight condensible can be negatively buoyant even if its temperature is higher than the surrounding environment.

The Effect of Planetary Rotation Period on Clouds in a Global Climate Model with a Bin Microphysics Scheme

The Astrophysical Journal
Clouds are the largest source of uncertainty in climate simulations. For exoplanets, cloud simulation is particularly challenging because of the lack of observational data to tune parameterized cloud models.

The Role of Emissivity in the Detection of Arctic Night Clouds

Remote Sensing, 2017
Detection of clouds over polar areas from satellite radiometric measurements in the visible and IR atmospheric window region is rather difficult because of the high albedo of snow, possible ice covered surfaces, very low humidity, and the usual presence ...

Nightside Clouds on Tidally Locked Terrestrial Planets Mimic Atmosphere-free Scenarios

The Astrophysical Journal Letters
We investigate the impact of nightside cloud formation on the observable day/night contrast of tidally locked terrestrial planet atmospheres. We demonstrate that, in the case where the planetary dayside is only 10 s of Kelvin hotter than the planetary ...

Atmospheric oxidation in the presence of clouds during the Deep Convective Clouds and Chemistry (DC3) study [PDF]

Atmospheric Chemistry and Physics, 2018
Deep convective clouds are critically important to the distribution of atmospheric constituents throughout the troposphere but are difficult environments to study.

Overview of atmospheric effects [PDF]

, 1980
Effluents from the transportation system are the major cause of Satellite Power System related atmospheric effects. These effects are discussed and include inadvertent weather modification, air quality degradation, compositional changes in the ...

CHARACTERIZATION OF CLOUDS IN TITAN'S TROPICAL ATMOSPHERE [PDF]

The Astrophysical Journal, 2009
Images of Titan's clouds, possible over the past 10 years, indicate primarily discrete convective methane clouds near the south and north poles and an immense stratiform cloud, likely composed of ethane, around the north pole. Here we present spectral images from Cassini's Visual Mapping Infrared Spectrometer that reveal the increasing presence of ...

The chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds

, 2005
We present a theoretical investigation of the chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds. The chemistry of interstellar fluorine is qualitatively different from that of any other element, because - unlike the ...

Evaluation of ARM Tethered Balloon System instrumentation for supercooled liquid water and distributed temperature sensing in mixed-phase Arctic clouds [PDF]

, 2019
A tethered balloon system (TBS) has been developed and is being operated by Sandia National Laboratories (SNL) on behalf of the U.S. Department of Energy’s (DOE) Atmospheric Radiation Measurement (ARM) User Facility in order to collect in situ ...
