From: Rapid modelling of the large-scale magnetospheric field from Swarm satellite data
Output | Description |
---|---|
Modified Julian Day | Time in decimal days since year 2000.0. This is the mid-point of the validity range of each 90 minute model in decimal days since midnight on morning of January 1st, 2000. |
Coefficients | Degree 1 internal and external spherical harmonic coefficients provided in Geographic (Earth-centred, Earth-fixed) and Solar Magnetic coordinates. Twelve coefficients in total. |
Number of data | The number of data contributing to each model, individually from each satellite. |
RMS differences | Root-mean-squared differences between X (north), Y (east), and Z (downward) magnetic field values from the model and the input data after subtraction of core, lithosphere, and ionospheric signals. |
Quality | A quality flag whose values indicate any issues with the model (zero indicates ‘no issues’). |
