Xenon-133 and caesium-137 releases into the atmosphere from the Fukushima Dai-ichi nuclear power plant: determination of the source term, atmospheric dispersion, and deposition
Andreas Stohl,Petra Seibert,Gerhard Wotawa,Delia Arnold,Delia Arnold,John F. Burkhart,Sabine Eckhardt,C. Tapia,Arturo Vargas,Teppei J. Yasunari +9 more
TL;DR: In this article, the authors determined the emissions into the atmosphere of two isotopes, the noble gas xenon-133 (133Xe) and the aerosol-bound caesium-137 (137Cs), which have very different release characteristics as well as behavior in the atmosphere.

Review of Aerosol–Cloud Interactions: Mechanisms, Significance, and Challenges
TL;DR: A review of recent theoretical studies and important mechanisms on aerosol-cloud interactions is presented in this article, which discusses the significances of aerosol impacts on radiative forcing and precipitation extremes associated with different cloud systems.

Andreas Kainz,Harald Steiner,Johannes Schalko,Artur Jachimowicz,Franz Kohl,Michael Stifter,Roman Beigelbeck,Franz Keplinger,Wilfried Hortschitz +8 more
TL;DR: The detection of force-induced displacements within compact MEMS (microelectromechanical system) devices can be used to measure electric field strength without significant field distortion.

Seasonal forecasting of lightning and thunderstorm activity in tropical and temperate regions of the world.
TL;DR: Variations in atmospheric parameters commonly associated with thunderstorm activity are found to provide a plausible physical explanation for the variations in lightning activity associated with El Niño/Southern Oscillation.

Atmospheric electric field measurements in urban environment and the pollutant aerosol weekly dependence
Hugo G. Silva,Hugo G. Silva,Ricardo Conceição,Marta Melgão,Keri Nicoll,P B Mendes,Mouhaydine Tlemçani,António Heitor Reis,R. G. Harrison +8 more
TL;DR: In this article, the weekly dependence of pollutant aerosols in the urban environment of Lisbon (Portugal) is inferred from the records of atmospheric electric field at Portela meteorological station (38°47′N, 9°08′W).

The physics of clouds
F. H. Ludlam,Basil John Mason +1 more
TL;DR: In the last fifteen years there has been a surge of activity in this science under the stimulus of development in civil and military aviation as discussed by the authors, and the growth of cloud physics during this period has been fostered not only by this general invigoration, but also by recognition of the practicability of exerting some influence upon the behaviour of clouds and their capacity for producing rain, hail, lightning and other meteorological phenomena.

Global frequency and distribution of lightning as observed from space by the Optical Transient Detector

TL;DR: In this article, the authors used the OTD measurements to construct lightning climatology maps that demonstrate the geographical and seasonal distribution of lightning activity for the globe, and found that lightning occurs mainly over land areas, with an average land/ocean ratio of 10:1.

Variation of cosmic ray flux and global cloud coverage—a missing link in solar-climate relationships
TL;DR: In this paper, the authors investigated the global cloud cover observed by satellites and found that the observed variation of 3-4% of the cloud cover during the recent solar cycle is strongly correlated with the cosmic ray flux.

TL;DR: First results from the CLOUD experiment at CERN are presented, finding that atmospherically relevant ammonia mixing ratios of 100 parts per trillion by volume, or less, increase the nucleation rate of sulphuric acid particles more than 100–1,000-fold and ion-induced binary nucleation of H2SO4–H2O can occur in the mid-troposphere but is negligible in the boundary layer.
