High-precision ionospheric region short-term forecasting method

Abstract

The invention discloses a high-precision ionospheric region short-term forecasting method which comprises the following steps: step 1, performing three-dimensional mesh generation on a selected regionaccording to longitude, latitude and height, with the longitude stepping by 2 degrees, the latitude stepping by 2 degrees and the height stepping by 20 km; step 2, establishing an ionospheric regionassimilation model; step 3, establishing an ionospheric single-station short-term forecasting method by adopting a comprehensive model of ionospheric parameter short-term forecasting; and step 4, establishing an ionospheric region immediate reporting and forecasting method in advance of 2 hours: adopting an ionospheric region assimilation forecasting technology based on Kalman filtering to realizeionospheric region immediate reporting and forecasting in advance of 2 hours. According to the high-precision ionospheric region short-term forecasting method disclosed by the invention, the ionospheric region data assimilation model is combined with a single-station short-term forecasting technology, so that the short-term forecasting capability of data assimilation is improved, a high-precisionlarge-region forecasting function of ionospheric parameters is realized, and the technical problem is solved.
