Dear Yury,

Check out this paper...

"Identification of vertical total electron content by time series analysis, Digital Signal Processing 19(4):740-749, 2009 by Erdogan H and Arslan N."

Yury Yasyukevich

We compared different filtering techniques. Our analysis revealed that one need to detrend data and then to select TEC variations. To detrend slant total electron content, cubic smoothing spline provided the best results among the versions analyzed. 6th-order polynomial also produced good results. For the variation selection, the centered moving average filter showed the best performance. The details can be found in the articleArticle Wave Signatures in Total Electron Content Variations: Filter...
