A langmuir multi-probe system for the characterization of atmospheric pressure arc plasmas [PDF]

open access: yes, 2003
The 'high-pressure' atmospheric (TIG) arc plasma is studied by means of a multi-Langmuir probe system. In order to determine the appropriate regime of operation, definitions of the plasma parameters for the description of the argon arc are considered and

Atmospheric Electricity, Geological Heterogeneity and Hydrogeological Processes

open access: yesProceedings, 2017
Elements of surface atmospheric electricity have never been used to solve problems of applied geophysics. A physical model representation of hydrogen, methane, radon, and elements of surface atmospheric electricity is constructed.

Development of Wireless Electric Field Mill for Atmospheric Electric Field Observation

open access: yesTELKOMNIKA (Telecommunication Computing Electronics and Control), 2014
Rotating-vane electric field mill (REFM) sensor is one of the popular methods to measure atmospheric quasi-static electric field. Lightning incident occasion can be predicted by observing electric fields strength in atmosphere. In this paper an integration of REFM with an online wireless data monitoring system for long distance observation and data ...

Static electric field detection and behavioural avoidance in cockroaches

open access: yes, 2008
Electric fields are pervasively present in the environment and occur both as a result of man-made activities and through natural occurrence. We have analysed the behaviour of cockroaches to static electric fields and determined the physiological ...

A Thunderstorm Cloud Point Charge Localization Method Based on CEEMDAN and SG Filtering

open access: yesIEEE Access, 2021
The current thunderstorm monitoring methods ignore the nonlinear and non-stationary characteristics of atmospheric electric field signals, which has a negative effect on the monitoring results. Based on complementary ensemble empirical mode decomposition

The role of the atmospheric electric field in the dust‐lifting process [PDF]

open access: yesGeophysical Research Letters, 2016
AbstractMineral dust particles represent the most abundant component of atmospheric aerosol in terms of dry mass. They play a key role in climate and climate change, so the study of their emission processes is of utmost importance. Measurements of dust emission into the atmosphere are scarce, so that the dust load is generally estimated using models ...
