Comparison of filter with Prairie and European Network data
Earlier notes derived a model for the hydrodynamics, ablation, and radiation of meteor impacts at the level needed to infer meteor parameters from observations and extended it to objects that fragment during entry, using models based on related cometary studies. This note completes the comparison of the resulting filter model to European and Prairie Network (EN and PN) data and models of meteor impact. In cases of mutual applicability, US and European models give broadly consistent results. The quantitative analysis of the EN and PN data is best discussed in conjunction with the Russian program of its analysis, because the Russian program has bypassed the large reported photometrically based masses to derive more plausible estimates of sizes, masses, and radiation efficiencies, which are the primary quantities of concern here. This note completes the discussion of the PN and EN data begun earlier, uses the data to produce filter predictions, and compares it with observations and the predictions of the Russian analytic effort. The overall agreement is useful in that the Russian efforts have employed more complex models that use observational data directly, while the filter model is at a level of simplification much better suited to data inversion.
