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.本数据集包含用于2025年11月12日至13日地磁风暴相关学术论文的中国地壳运动观测网络（CMONOC）与川滇试验台网的斜向总电子含量（slant total electron content, TEC）观测数据。该归档包含年积日316（对应2025年11月12日）的342个台站级.tec格式文件。每个文件存储卫星弧段记录，涵盖日期、日秒数、卫星PRN（伪随机噪声码）、台站标识、斜向TEC（STEC）、映射函数以及电离层穿透点经纬度字段。上述数据支撑该论文的分析工作及图4至图7的绘制，涵盖北斗地球静止轨道（GEO）TEC变化、区域行进电离层扰动诊断、TEC变化率指数（ROTI）分布图以及极光时序图（keogram）相关产品。 上传的源归档文件名为cmonoc_sichuan_yunnan_slant_tec_20251112.zip。上传前本地源归档的校验值说明如下：MD5为b5a18ba17e8311b7432a310b1855efbd；SHA-256为a738b5e158f9f6ae55756c5f12cee3fbd16da831310926a346c88e876991c4fd。
