IMAGE magnetometer network data

Rules of the road

Accuracy of data

Data availability

Formats

The magnetic field components are the geographical ones: X (north), Y (east), Z (downwards). The following file formats are available:

1. IAGA format: basic IMAGE format
2. WDC: one minute values
3. Simple column format
4. GADF

In all cases, we follow the IAGA time definition (however, see also comments about the accuracy of data).

Data on WWW

1. On-line magnetograms

2. Request form for data files in various formats, and another form for monthly data

3. Locations of electrojets (quick-look)

Interactive data tools

1. IMAGE electrojet indicators (IL, IU, IE)

2. 1D equivalent currents

3. 2D equivalent currents

Software for data manipulation

CD-ROMs

CD-ROMs or DVDs are nowadays produced primarily for backup purposes. To get long data sequences, please use the on-line request form for monthly files.
