Web based IONOLAB TEC Estimation

Because of the effects on radio waves, monitoring the ionosphere gains significant importance. Monitoring of the ionosphere becomes possible by estimating Total Electron Content (TEC) which is the major variable expressing ionospheric effects. Although International Reference Ionosphere (IRI) and International GNSS Service (IGS) analysis centers can generate TEC estimates, these estimates either have low temporal resolution or are based on emprical data. IONOLAB (www.ionolab.org) TEC estimation method provides robust estimations with high temporal resolution compared to IGS analysis centers. In this work, robust TEC estimations with high temporal resolution generated by IONOLAB method are presented by an easily accessible, user-friendly application. The application has a layered modular design. By means of this modular design, possible changes regarding the estimation method can be easily adapted.
