Research on Short-term Ionospheric Prediction Combining with EOF and ARIMA Model Over Guangxi Area [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
According to the empirical orthogonal function (EOF), the non-stationary time series data are decomposed into time function and space function, so this mathematical method can simplify the non-stationary time series and eliminate redundant information ...
