Real-time versus postprocessing IGS combined global TEC maps: examined by Jason-3 altimetry and DORIS observations

Key Points

• TEC maps demonstrate significant differences when compared in real-time versus postprocessing methods, suggesting variations in accuracy.
• Using Jason-3 altimetry data and DORIS observations, researchers identify the strengths of each TEC mapping method across various conditions.
• Observational analysis using altimetry and DORIS identifies real-time advantages for immediate data applications and geospatial integrations.
• Findings support the need for further refinement in TEC mapping techniques for enhanced global navigation and climate studies.
