| Zusammenfassung |
| In the framework of this paper, one-year of lightning data from the
experimental network ZEUS operated by the National Observatory of Athens is
compared to collocated data provided by the LINET detection network. The area
of comparison is limited to a part of Central-Western Europe, where LINET
data exhibits the highest data quality, permitting thus to be used as the
validation dataset. The location error of ZEUS was calculated to be
~6.8 km, while the detection efficiency was ~25%, with a
characteristic under-detection during nighttime. Moreover, the analysis
revealed that ZEUS is also capable to detect not only cloud-to-ground but
also intra-cloud strokes. Analysis of a specific case study revealed that the
spatial distribution of ZEUS was very close to that of LINET, although the
total number of strokes as seen by ZEUS is much lower than the one from
LINET. The overall analysis permitted to assess the main characteristics of
ZEUS network, information considered of paramount importance before the use
of ZEUS data for a variety of observational and modeling work. |
