Our measuring network focuses on the Earth's ionosphere. It's an upper atmospheric layer which is located approximately in the heights from 60 km to 1000 km. Thanks to the solar activity, the neutral gas is ionized in the ionosphere so the low temperature plasma is created there. Except the Sun, the ionospheric plasma can be influenced by the Jupiter magnetic storms, meteors or some strong gamma ray bursts. In accordance with the height where the plasma is loca… text/html 2016-04-11T20:50:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.ionozor.cz/doku.php?id=en:data-outputs&rev=1460407800&do=diff Ionozor data output types VLF measurement VLF Data Analysis HF measurement HF Data Analysis The data from our measuring stations are going to be saved onto the Ionozor web storage from where they will be automatically generated as the appropriate graphs.

The VLF measurement gives us the basic paramteres of the upper D ionospheric layer. Within the digisonde measurement, we can get the similar diagnostics for the E and F region, possibly the sporadic E layer. However, if some more informations about the phenomenon influencing the ionosphere are required, another measurement needs to be conducted. The high frequency measurement, in fact, has a quite broad range of use. text/html 2017-01-05T13:43:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.ionozor.cz/doku.php?id=en:join&rev=1483623780&do=diff Get involved Would you like to join us? Our network is opened for everyone who would like to take part at the modern investigation of the ionosphere. If you are a researcher or a radio amateur who conducts a measurement station such as the VLF or HF measurement or the Doppler measurement, you are very welcome.

The typical example of that place is an astronomical observatory. Stations send files containing measured data to the server space.astro.cz through SCP protocol. At first, a station has to generate a key pair (if it has not done it already), that will be used for station authentication when communicating with server. text/html 2016-03-29T19:14:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.ionozor.cz/doku.php?id=en:sidebar&rev=1459278840&do=diff Basic information * How does it work? * Get involved * Data outputs * FAQ Development * TODO list * GitHub Community * Mailing List text/html 2016-04-09T21:38:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.ionozor.cz/doku.php?id=en:start&rev=1460237880&do=diff Ionozor measuring network It is a project of cooperative network which uses technical devices situated at volunteer observers, which operate measuring stations.

The SID monitors are inductive coils that receive radio signal from a transmitter with the characteristic frequency given. While the signal spreads through the ionospheric plasma, its intesity changes in dependence on the current electron density. We model the electron plasma frequency using the measurement of the radio signal intensity level, which helps us to determine other quantites and phenomena. The transmitter’s characteristic …
