Description

2025-Jan AMPERE GRD and IRD data.

AMPERE IRD files contain hemispheric delta-B observations in global coordinates (geographic and AACGM). Data are blocked into 10-minute 'chunks' at 2-minute resolution for use in the fitting algorithm. Measurements flagged 'bad' in the earlier processing are removed prior to entry in IRD.

AMPERE GRD files contain hemispheric delta-B and Birkeland current fits at 2-minute resolution.
