Hayden Johnson developed new Total Electron Content (TEC) data converters for the JCSDA-internal/ioda-converters repository, enabling ingestion of Madrigal TEC data in both NetCDF and HDF5 formats. He reorganized existing space weather converters into a dedicated directory and renamed files to better reflect their data types, improving code maintainability. His work introduced an optional window length parameter and explicit handling of GPS versus GLONASS data, enhancing flexibility for scientific data processing. Using CMake and Python, Hayden focused on data conversion and file I/O, laying a foundation for future extensibility and supporting more robust scientific workflows within the repository.
