Plume-top altitude time-series during May 2011 volcanic eruption of Grímsvötn, Iceland

Plume-top altitude time series of the volcanic plume during the eruption of Grímsvötn in Iceland 21-28 May 2011. The altitude was estimated from weather radar echo top data from two weather radars, Keflavik and Klaustur. Keflavik radar is a fixed position C-band weather radar close to Keflavik International Airport, at 64°01.583'N, 22°38.150'W. The height of the antenna is 47 m a.s.l. and the distance to Grímsvötn volcano is 257 km. Klaustur radar is a mobile X-band weather radar located close to Kirkjubaejarklaustur, at 63°46.500'N, 17°57.817'W. The height of the antenna is also 47 m a.s.l. and the distance to Grímsvötn volcano is 75 km.

本数据集记录了2011年5月21日至28日冰岛格里姆斯沃特纳（Grímsvötn）火山喷发期间火山羽流顶部海拔的时间序列数据。该海拔高度通过凯夫拉维克（Keflavik）与克劳斯特尔（Klaustur）两台天气雷达的回波顶数据反演估算得出。其中，凯夫拉维克雷达为固定部署的C波段天气雷达，毗邻凯夫拉维克国际机场，地理坐标为北纬64°01.583′、西经22°38.150′，天线海拔高度为47米，距格里姆斯沃特纳火山的直线距离为257千米；克劳斯特尔雷达为移动部署的X波段天气雷达，位于柯曲比约尔克克劳斯特尔（Kirkjubaejarklaustur）附近，地理坐标为北纬63°46.500′、西经17°57.817′，天线海拔高度同样为47米，距格里姆斯沃特纳火山的直线距离为75千米。
