Description

A major aspect in the upgrade towards MASTER-8 was to come up with a functionality to assess flux uncertainties for the artificial space debris. The methodology is based on the comparison between measurements and the model output, expressed via the error-ratio. Depending on that ratio it was possible to have certain metrics defined for the first time in MASTER's validation process that go beyond the qualitative assessment of the results by a trained expert. Those metrics give an indication of the model fit to what has been measured and pave the way for further automation in the validation process of the model. Due to very heterogeneous data sources covering size regimes from microns up to tens of metres in different orbital regions, a sensible weighting has to be applied. In this talk, the basics behind the methodology to derive flux uncertainties will be explained.
