[MIS16-P01] Volcanic ash plume height estimation by weather radar
Keywords:volcanic ash plume, weather radar
Although there were many eruption cases which were captured by weather radar (e.g. Sawada, 2003), few cases were sequentially captured in time (e.g. Harris et al., 1983; Arason et al., 2011; Shimbori et al., 2013). There are two main reasons. One is that scales of many eruption cases were not enough to be sequentially detected by weather radars. The other is that records of many eruption cases were not left because radar data weren't digitized in past. After the digitization of weather radars, eruption cases captured by weather radar have been gradually accumulated.
In this presentation, the overview of the method, problems to be solved, and future prospects will be discussed.
