Dst Index (TsFile)

Apache TsFile version of juliensimon/dst-index.

Overview

Hourly Dst (Disturbance storm-time) index series — a measure of geomagnetic storm intensity derived from equatorial magnetometer stations. 590,683 hourly records spanning 1957-01-01 to 2026-06-10 (UTC), with strictly increasing, unique timestamps. Data originate from the WDC for Geomagnetism, Kyoto.

Schema (TsFile structure)

Time (INT64, milliseconds, UTC) — the hourly timestamp.
series (TAG) — main (the full 5-column series, 590,683 rows) and daily_mean (the daily_mean_nt column, available from 2000 onward, 192,355 rows). Splitting by this TAG keeps both series complete in one file.
FIELD: dst_nt / daily_mean_nt (DOUBLE), quality / storm_intensity (STRING), is_storm (BOOLEAN).

No column or row is dropped; null values are preserved.

Usage

Read data.tsfile with the Apache TsFile Java or Python SDK.
