The UV-visible spectrometer SALOMON, dedicated to the retrieval of vertical profiles of O3, NO2 and NO3, has performed measurements on 19 September 2002, from Aire sur l’Adour (France) between 20h00 and 22h30 TU. At the same time, an ozone sounding has been launched. GOMOS has performed measurements at 21h24 UT, with a spatial coincidence with SALOMON and the sounding of around 250 km. Then, al...

Today, the need for new sites construction of modern facilities is growing every year as a result rapid development “construction buildings and industrial facilities” in Uzbekistan. New, sparsely populated ecologically clean territories are selected facilities, studied detail using geophysical methods to improve quality increase level durability structures. The following article devoted study g...

Oblique sounding may be used to obtain information about the ionosphere, in the form of an electron density profile, near the mid-point of two sites. This makes it useful for recovering ionospheric data at a point at which, for reasons of economy or geography, vertical sounding cannot be conducted. The information may be used in providing real-time propagation advice either for over-the-horizon...

Proximal sensing of soil electromagnetic properties is widely used to map spatial land heterogeneity. The mapping instruments use galvanic contact, capacitive coupling or electromagnetic induction. Regardless of the type of instrument, the geometrical configuration between signal transmitting and receiving elements typically defines the shape of the depth response function. To assess vertical s...

many recent researches have been devoted to investigating the connection between seismic activity and ionospheric variations. it has been shown that the behavior of characteristic parameters of the ionosphere can be used as temporal and spatial precursors of strong earthquakes ( ). in the present work variations of critical frequency of ionospheric f2 layer as a temporal precursor for the qom e...
