Geomagnetic Kp Index (3-Hourly) — TsFile

从 HuggingFace 数据集 juliensimon/geomagnetic-kp-index 转换为 Apache TsFile 格式。

原始数据来自 NOAA SWPC（Space Weather Prediction Center），为 3 小时粒度的行星地磁 Kp 指数（衡量全球地磁扰动的 0–9 准对数标度）。

来源

原始数据集：juliensimon/geomagnetic-kp-index
原作者：Julien Simon (juliensimon)
数据源头：NOAA SWPC
许可证：CC-BY-4.0（以原数据集为准）

数据内容

686 行 × 5 列，时间范围 2026-03-17 → 2026-06-10（UTC），每天 8 个读数（00 / 03 / 06 / 09 / 12 / 15 / 18 / 21 UT）。单设备、单条时间序列。

列	TsFile 类型	角色	说明
`Time`	INT64 (ms)	时间列	由原 `datetime`（UTC 时间戳）转为毫秒
`kp_value`	DOUBLE	FIELD	Kp 指数 0.0–9.0；≥5 表示地磁暴
`ap_running`	INT64	FIELD	24 小时滚动 ap 均值（线性标度，nT）
`station_count`	INT64	FIELD	贡献观测台站数（最多 13）
`storm_level`	STRING	FIELD	NOAA G 级标签：quiet / G1-minor / G2-moderate / G3-strong / …

转换说明

转换路径：script（自定义转换器 scripts/converters/geomagnetic_kp_index.py）
时间精度：ms
未声明 TAG：本数据集是单设备宽表，所有测量列均为 FIELD。
不丢弃任何列：原始 5 列全部保留（datetime → Time，其余 4 列原样保留）。
原始数据无缺失值；时间序列严格递增、无重复时间戳。
读回校验：TsFile 读回 686 行，与源完全一致。

用法

from tsfile import TsFileReader

reader = TsFileReader("geomagnetic_kp_index.tsfile")
for name, schema in reader.get_all_table_schemas().items():
    print(name, [c.get_column_name() for c in schema.get_columns()])
