Figure 6. Observed green intensities and model fits for the 25 May 2020 green ghost sprite. The ordinate is in arbitrary units, and the abscissa is in ms from the onset of the sprite.
The proposed model for the green ghost fits the observations surprisingly well given its simplicity. The main fitting problem between model and observations is in box 6 and 7 of the 24 May 2020 event where the observed initial rise is later that the model predicts. There could be an issue with the background subtraction, or the assumed electric field might be established later at the lower altitude represented by box 6 and 7.
To allow some quantitative assessment of the analysis and model we list key parameters for the analysis of the two events:
