Atmospheric ions and nucleation: a review of observations [PDF]

Atmospheric Chemistry and Physics, 2010
Abstract. This review is based on ca. 250 publications, from which 92 published data on the temporal and spatial variation of the concentration of small ions (<1.6 nm in diameter) in the atmosphere, chemical composition, or formation and growth rates of sub-3 nm ions.

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

, 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 ...

Visual Observations of the Solar Atmosphere [PDF]

Proceedings of the National Academy of Sciences, 1926
The spectrohelioscope, an instrument for observing the sun in monochromatic light, has been briefly described in a previous article. (1) The same optical parts employed in the preliminary work are now rigidly mounted in a vertical position in my new Solar Laboratory in Pasadena (a branch of the Mount Wilson Observatory).
