HF Data Analysis

What is supplied by the supplemental HF measurement?
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.
The appropriate machine used to the HF measurement is a very small radio telescope. Our construction is similar to the ones which have earlier been used within the NASA Radio Jove Project, see http://radiojove.gsfc.nasa.gov/. Its scheme is given in Figure 1.

Originally, such a gadget was projected to measure the magnetic field's variations coming along the solar eruption, some coronal mass ejections and the Jupiter magnetic storms. Such data provides us to analyze the spectra of fragmented and ionized molecules in the ionosphere and also some other physical parameters of the ionospheric plasma, such as the electron plasma frequency. For more data, have a look at the Github repository or the data storage.
