RIOMETRIC METHOD OF DETERMINING GEOMAGNETIC CUTTING STIFFNESS FACTOR Russian patent published in 2016 - IPC G01T1/29 

FIELD: measurement technology.

SUBSTANCE: invention relates to methods of determining "geomagnetic cutting stiffness factor" (GCSF) - one of geophysical parameters, which is used for monitoring the radiation environment and propagation of short radio waves in the magnetosphere and the ionosphere of high auroral latitude after powerful solar flares in the period of increased abnormal absorption of radio waves in polar regions (in the period of so-called "Polar Cap Absorption" - PCA). Riometric method of determining the geomagnetic cutting stiffness factor comprises the steps, wherein the absorption is measured by a riometer on the selected station of auroral zone with simultaneous measurement of solar protons flow intensity by means of detectors mounted on a geostationary satellite, absorption of radio waves is measured by known method, this value is compared with the measured one, and in case of mismatch, the value of the lower boundary of the energy spectrum of solar protons flows is increased, new measurement of absorption will be performed, the procedure is repeated until the concurrency of calculated absorption with the measured one is achieved, and in this case the value of the lower boundary of the energy spectrum of solar protons flow is recalculated by known method in units of stiffness.

EFFECT: obtaining more accurate and operational values of GCSF for PCA analysis.
