Abstract
The dataset contains definitive minute values of the geomagnetic field based on observations from the Irkutsk INTERMAGNET magnetic observatory (IAGA code: IRT) for the period from 1 January to 31 December 2021. The components X (Northward), Y (Eastward), and Z (Downward) are provided. Components X and Y are calculated from the source records of H (horizontal component) and D (declination); component Z is recorded directly. Additionally, the quantity G is provided — the difference between the magnitude of the field vector computed from components X, Y, and Z and the magnitude of the total vector F measured independently by a scalar magnetometer. The data are provided in IAGA-2002 and Intermagnet Archive Format (IAF) Access to the data is open.
