全体主题 > New developments in ENDE

An integral part of our environment in addition to the surface of the Earth is the adjacent part of the atmosphere, the lower layer of the troposphere. This part of the troposphere has essential influence on weather evolution and information on its condition is an important part of the weather forecasting models. Standard methods of the data acquisition such as radars, satellites and weather stations do not provide information with sufficiently high temporal and spatial resolution. The subject of the article is a new method of monitoring the condition of the low layers of the atmosphere which is based on passive
monitoring and evaluation of parameters of high frequency radio electromagnetic
field signals from communication systems, such as the Base Transceiver Stations
(BTS) of mobile operators, digital terrestrial TV and radio transmitters, etc. The
elementary theory of an virtual sensor for the atmospheric radio refractive index
monitoring and the preliminary results of experimental monitoring of the selected
meteorological situation are presented.
