资源简介:

High-speed imaging and acoustic measurements of volcanic vortex rings at Stromboli in two days in 2018 and 2019. The .mat files from 20180912_0953_1 to 20190511_1327_1 (yyyymmdd_hhmm_#) include the acoustic data (Pa), sampled at 10 kHz. The axial_position_data.mat file includes two variables: ringrise2018 (81x63) and ringrise2019 (21x30). In the ringrise2018 variable, columns from 1 to 3 (and repeat) are, for each VVR, (1): time (s); (2): vertical position above vent (m); (3): rise velocity (m/s); In the ringrise2019 variable, columns from 1 to 5 (and repeat) are, for each VVR, (1): vertical position above the vent (m); (2): lateral position (m); (3): time (s); (4): measuring line length (m); (5): rise velocity (m/s). The VVR_data.mat file includes two variables: VVR_2018 (21x5) and VVR_2019 (7x5). In both variables, columns from 1 to 5 are: (1): acoustic peak prominence (Pa); (2): acoustic peak width (s); (3): max VVR rise velocity (m/s); (4): VVR-particle delay (s); (5) mean particle velocity in the first 0.1 s (m/s).

本数据集为2018年与2019年期间于斯特龙博利火山(Stromboli)开展的为期两日的火山涡环高速成像与声学测量数据。命名格式为年日月_时分_序号(即yyyymmdd_hhmm_#)、编号范围为20180912_0953_1至20190511_1327_1的.mat格式文件,包含采样率为10 kHz的声学数据(单位:帕斯卡,Pa)。axial_position_data.mat文件包含两个变量:ringrise2018(尺寸81×63)与ringrise2019(尺寸21×30)。对于每个火山涡环(Volcanic Vortex Ring,简称VVR),ringrise2018变量的每3列(循环重复)对应以下参数:(1) 时间(秒,s);(2) 喷口上方垂直位置(米,m);(3) 上升速度(米每秒,m/s)。而ringrise2019变量的每5列(循环重复)对应单个VVR的以下参数:(1) 喷口上方垂直位置(m);(2) 横向位置(m);(3) 时间(s);(4) 测量线长度(m);(5) 上升速度(m/s)。VVR_data.mat文件包含两个变量:VVR_2018(尺寸21×5)与VVR_2019(尺寸7×5)。两个变量的每5列参数均为:(1) 声学峰值突度(Pa);(2) 声学峰值宽度(秒,s);(3) VVR最大上升速度(m/s);(4) VVR-颗粒延迟时间(s);(5) 初始0.1秒内的平均颗粒速度(m/s)。
