Kakioka geomagnetic field 7.5-second digitized data in IAGA-2002 format, extracted from magnetograms

ResourceID
spase://IUGONET/NumericalData/KMO-JMA/KAK/Magnetogram/PT7.5S

Description

The geomagnetic field 7.5-second digitized data in IAGA-2002 format, extracted from magnetograms at Kakioka (KAK). The data may include reading errors. When a trace is overlapped with a baseline on the magnetogram, the missing value with 99999 may be embedded.

Name
Geomagnetic field digitized from magnetograms
Description

7.5-second values are calculated by interpolation of 7.62-second values. Then 7.5-second values are calibrated using absolute values observed at a one-week interval. The data may include daily variation caused by temperature change. D(eastward+)[arc minute], H[nT], Z(downward+)[nT], F[nT]
