Altitude estimates of the volcanic plume-top of Grímsvötn measured by X-band weather radar (Klaustur)

Code: 1000: Plume-top is below radar minimum detection height (about 2.5 km) 2000: Plume-top could not be determined from radar data because of precipitating clouds at the volcano values 2.4 - 19.7: Plume-top altitude estimate (km a.s.l), measured by radar编码： 1000：烟羽顶（Plume-top）低于雷达最低探测高度（约2.5千米） 2000：因火山上空存在降水云，无法通过雷达数据确定烟羽顶高度 2.4 - 19.7：由雷达测得的烟羽顶高度估算值（单位：千米海拔，km a.s.l.）
