Radiophysics and Quantum Electronics Aims and scope

Abstract

To estimate the solar radiant flux by an indirect route in the spectrum region from 10 to 30 nm, which is difficult for direct measurement, we propose to use the data on the electron density in the E region maximum and E-F1 valley. Taken from empirical models, the data on these parameters were correlated with theoretical calculations. It is shown that at wavelengths of from 10 to 30 nm the solar radiant flux is about 2.5 times greater than that measured from the AE- E satellite. The results are used to correct the model spectra of extreme UV radiation.
