CMONOC and Sichuan-Yunnan slant TEC dataset for the 12-13 November 2025 geomagnetic storm

This dataset contains CMONOC and Sichuan-Yunnan experimental network slant total electron content (TEC) observations used in the manuscript on the 12-13 November 2025 geomagnetic storm. The archive contains 342 station-level .tec files for day-of-year 316 (2025-11-12). Each file stores satellite arc records with day, seconds of day, satellite PRN, station identifier, slant TEC (STEC), mapping function, and ionospheric pierce point latitude/longitude columns. These data support the manuscript analyses and Figures 4-7, including BeiDou GEO TEC variations, regional traveling ionospheric disturbance diagnostics, ROTI maps, and keogram products. The uploaded source archive is named cmonoc_sichuan_yunnan_slant_tec_20251112.zip. Checksum notes for the local source zip before upload: MD5 b5a18ba17e8311b7432a310b1855efbd; SHA-256 a738b5e158f9f6ae55756c5f12cee3fbd16da831310926a346c88e876991c4fd.
