Table 1. Daily Quick-Look images and purpose for magnetic field Level 1b data. See Section 2 for a detailed explanation.
From: Independent validation of Swarm Level 2 magnetic field products and ‘Quick Look’ for Level 1b data
Quick Look graphical image | Purpose |
|---|---|
Map showing coverage of F and BNEC from each satellite | Identification of spatially correlated data gaps |
Time series plots: differences between F (total field strength) and ǀBNECǀ (strength of the North, East and Centre components) | Identification of gross errors and inspection of flag values |
Time series plots: first differences for each satellite | Identification of steps and spikes |
Inter-satellite (lower pair) differences, time series plots, daily correlations for mission to date | Identification of steps and spikes in data |
Spectra of differences between F and ǀBNECǀ | For detection of periodic signals |
Time series plot: differences from model | Identification of steps, spikes and drift |
