Geomagnetic Components D, H, X, Y, Z, and R 10-second Instantaneous Measurements
These data are generated as part of the International Magnetospheric Study. The file consists of 10-second instantaneous measurements for the geomagnetic components D, H, X, Y, Z and R. The 10 second values were collected digitally in real time by a network of 26 ground observatories and relayed to the Space Environment Center, Boulder, Colorado, via the SMS-GOES satellite and the Wallops Island, Virginia ground station. The 1-minute average values are computed at the Space Environment Center in Boulder, Colorado. The entry ID number for the 1-minute values is Dataset_ID G00124. These data were generated as part of the International Magnetospheric Study. The file is comprised of values of the geomagnetic components D, H, X, Y, Z and R from instantaneous measurements taken at 10-second intervals at ground observatories. The 10-second values are collected digitally in real time at the magnetic observatories and relayed to the Space Environment Center via the SMS-GOES satellite to up to 26 geomagnetic observatories that provide data. The data are not continuous in time for all observatories and not necessarily continuous in time sequence for all elements at any one observatory. The sources for the data are the following chains of geomagnetic observatories: Alaska Chain, Churchill Chain, East-West Chain and Mid-Latitude Chain.
