Both datasets contain the following measurements of physical variables of: All the data measured by float #1901730; All the data measured by the whole Argo fleet between April 1, 2022 and April 30, 2022. ARGO_PHY_SAMPLE_NOQC was built retrieving the data served by the Argo GDAC as of March 27, 2025 and converted them to parquet. ARGO_PHY_SAMPLE_QC was built performing filtering the data in ARGO_PHY_SAMPLE_NOQC by QC flags and is considered a "best available measurements" version.
