Developed and delivered the CO2_fundamental_PhamTsung.csv dataset for the FoleyLab/data_repository, focusing on enabling reliable spectroscopy analysis through meticulous data preparation. The work involved comprehensive data cleaning and standardization, including precision normalization and consistent formatting across the dataset. An erroneous data point was identified and removed to enhance data integrity and analytical reliability. All modifications were tracked through a clear, commit-level history, supporting reproducibility and auditability for future research. The project utilized CSV as the primary data format and emphasized data quality improvements, ensuring the dataset could be confidently used in downstream scientific workflows and collaborative research environments.
