Problems solved by technology

[0003] Many analyzes and studies have found that when the atmospheric model evaluates the density of the orbital atmosphere, it usually overestimates and underestimates. When the international standard Kp index is used to input the atmospheric model, the 1-day density integration error of the calculation result sometimes exceeds 1 times

Abstract

The invention provides a geomagnetic activity index correction method and system based on an MSISE00 atmospheric model, a medium and a terminal. The geomagnetic activity index correction method comprises the following steps: obtaining polar region energy injection data; calculating an average energy injection rate in every three hours based on the polar region energy injection data; calculating corrected geomagnetic activity indexes in every three hour intervals based on the average energy injection rate; and obtaining a corrected geomagnetic activity index corresponding to one natural day ora specified time interval based on the corrected geomagnetic activity indexes in every three hour intervals. According to the geomagnetic activity index correction method and system based on the MSISE00 atmospheric model, the medium and the terminal, the geomagnetic activity index input by the MSISE00 atmospheric model is corrected based on the statistical relationship and change rule of the polarregion energy injection and the geomagnetic activity index, so that the calculation precision of the atmospheric model is obviously improved.

Description

technical field [0001] The present invention relates to the technical field of geomagnetic activity index, in particular to a method, system, medium and terminal for correcting geomagnetic activity index based on the MSISE00 atmospheric model. Background technique [0002] The impact of space weather on the upper atmosphere is mainly determined by the magnitude of the energy injection in the Earth's polar regions that accompanies geomagnetic disturbances, and is statistically positively correlated with the strength of geomagnetic activity. the magnitude of change. The polar region energy injection is obtained through the analysis of the results of NOAA series satellites and low-energy particle detectors carried by European Space Agency (ESA) polar-orbiting meteorological satellites. The geomagnetic activity index is obtained comprehensively from the geomagnetic stations on the ground. As far as the changes in the upper atmosphere are concerned, the energy injection in the ...
