GNSS RINEX observation data (University of Macau) for GNSS‑IR analyses: UMLC & UMTR during Wipha, Tapah, and Ragasa

This Zenodo record provides GNSS observation data in RINEX format collected at two University of Macau (UM) GNSS stations (UMLC and UMTR) during three event periods: Wipha, Tapah, and Ragasa. The data are intended to support GNSS Interferometric Reflectometry (GNSS‑IR) studies, including extraction of SNR time series for environmental/geophysical inversions. Files included Six compressed packages are provided (each package contains the RINEX files for a specific station and event period): UMLC‑Wipha UMLC‑Tapah UMLC‑Ragasa UMTR‑Wipha UMTR‑Tapah UMTR‑Ragasa Important note on RINEX header timestamps Due to limitations of the data transmission/recording software used during collection, the satellite header timestamp fields in some RINEX files may not be consistent with the true observation period (i.e., header date/time were not automatically updated during logging). Crucially, the observation data records below the header (epoch time tags and measurements) are correct and internally consistent, and the files can be used normally to extract SNR sequences and perform GNSS‑IR inversion. Recommendation: When parsing these data, please rely on the epoch time tags in the observation body rather than the header timestamps. Users may optionally correct header timestamps for bookkeeping purposes, but this is not required for SNR extraction and GNSS‑IR processing.
