Geomagnetic field
Description
Original one-second values are added to provisional baseline values. One-minute values are calculated as averages of 60 one-second values, centered on the minute. Then one-minute values are calibrated using absolute values observed at a one-week interval. D(eastward+)[arc minute], H[nT], Z(downward+)[nT], F[nT]
