  "description": "Kakioka (KAK) 0.1-second geomagnetic field variations (H, E, Z) recorded by the Kakioka Magnetic Observatory, Japan Meteorological Agency. H, E and Z are VARIATION components in nT, where H is along the magnetic meridian (northward+), E is the magnetic eastward variation in nT (not minutes of arc) and Z is vertical (downward+). They are not absolute field measurements and carry no baseline: use them for variations, not for absolute levels, and do not compare levels between stations or across time. The values are served as recorded and are NOT corrected for the frequency response of the recording system: the source supplies sensitivity tables (amplitude and phase against period, 1 to 200 s) whose amplitude factors are close to 1 at periods of a few to tens of seconds but grow to about 3 at 200 s, so long-period variations are recorded smaller than they are. Timestamps are the sample times of the source (timeStampLocation=center). Variation data without baseline, as recorded.",
