Soil-Air exchange controls on background atmospheric concentrations of organochlorine pesticides [PDF]

open access: yes, 2011
Soils are the major terrestrial reservoir of persistent organic pollutants, and thus net volatilization from soil, when it happens, may exert a control on the atmospheric occurrence and variability of organic pollutants.

Abiotic ozone and oxygen in atmospheres similar to prebiotic earth [PDF]

open access: yes, 2014
The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...

Inverse modeling of European CH4 emissions: sensitivity to the observational network [PDF]

open access: yes, 2009
Inverse modeling is widely employed to provide “top-down” emission estimates using atmospheric measurements. Here, we analyze the dependence of derived CH4 emissions on the sampling frequency and density of the observational surface network, using the ...

A Blind Search for Transit Depth Variability with TESS

open access: yesThe Astronomical Journal, 2023
The phenomenon of transit depth variability offers a pathway through which processes such as exoplanet atmospheric activity and orbital dynamics can be studied.

Small Interannual Variability of Global Atmospheric Hydroxyl [PDF]

open access: yes, 2011
The oxidizing capacity of the global atmosphere is largely determined by hydroxyl (OH) radicals and is diagnosed by analyzing methyl chloroform (CH3CCl3) measurements.

Variability of atmospheric dimethylsulphide over the southern Indian Ocean due to changes in ultraviolet radiation [PDF]

open access: yes, 2003
Dimethylsulphide (DMS) is a climatically important component of global biogeochemical cycles, through its role in the sulphur cycle. Changes in ultraviolet radiation (UV) exhibit both positive and negative forcings on the dynamics of production and ...

A Lack of Variability between Repeated Spitzer Phase Curves of WASP-43b

open access: yesThe Astronomical Journal, 2023
Though the global atmospheres of hot Jupiters have been extensively studied using phase curve observations, the level of time variability in these data is not well constrained.

Earth as an Exoplanet: Investigating the Effects of Cloud Variability on the Direct-imaging of Atmospheres

open access: yesThe Planetary Science Journal
Abstract A planet’s spectrum is dynamic and only represents a time-dependent snapshot of its properties. Changing atmospheric conditions due to climate and weather patterns, particularly variation in cloud cover, can significantly affect the spectrum in ways that complicate the understanding of a planet’s baseline atmospheric properties.

Decadal-interdecadal climate variability over Antarctica and linkages to the Tropics : analysis of ice core, instrumental, and tropical proxy data [PDF]

open access: yes, 2012
The Antarctic continent contains the majority of the global ice volume and plays an important role in a changing climate. The nature and causes of Antarctic climate variability are, however, poorly understood beyond interannual time scales due to the ...
