Overview

About IonoDataFilter

This software detects outliers in ionosonde data.

It contains

  • Reader IonoData

and the three following filters:

  • Filter “Option 4”
  • Filter scikit-learn, MCD simple
  • Filter scikit-learn, MCD correlation

Reader IonoData

This class collects functions to read specific ionosonde data files and returning dictionaries of this data.

Filter Option 4

This class filters ionosonde data with Filter Option 4 specified in the technical note TN_TG_07_03_14_IS_datenFilterung.docx by Tatjana Gerzen.

This is a translation of the MATLAB program IS_QualityCheck/MainIonosonde_QualityCheck.m by Tatjana Gerzen.

Filter Scikit, MCD simple

This class filters ionosonde data using the sklearn.covariance functions MinCovDet().fit() and reweight_covariance(). MCD simple uses only one ionospheric parameter (NmF2 or hmF2).

Filter Scikit, MCD correlation

This class filters ionosonde data using the sklearn.covariance functions MinCovDet().fit() and reweight_covariance(). MCD_correlation uses both parameters (NmF2 and hmF2).
