Notes. Columns are (from left to right): bibliographic reference of the study, name or acronym of the experiment, observational technique, magnitude, or mass range of the dataset and mass index (with 1σ uncertainty when provided by the authors). Since not all authors report a direct estimation of the considered mass range of meteoroids, the magnitude range should provide a rough indication of it. However, the reader must be aware that magnitude scales may not be directly comparable with one another (especially when comparing optical and radar measurements). In the case of SAAMER, the authors specify that: “[…] the mass range detected by SAAMER is most likely an overlap between CMOR and AMOR” (Janches et al. 2019). The acronyms of the experiments are: HMP = Harvard Meteor Project, SMO = Springhill Meteor Observatory, HF = high frequency, MFS = meteor forward scatter, AMOR = Advanced Meteor Orbit Radar, CMOR = Canadian Meteor Orbit Radar, CAMO = Canadian Automated Meteor Observatory, SAAMER = Southern Argentina Agile MEteor Radar, and Mini-EUSO for this work.
