VLF wideband data and fluxgate magnetometer data from Dunedin, 11 May 2024

This archive has two files. Both are text files. Hires_HWB_UWB20240511.txt is a very low frequency wideband dataset taken from Otago University's aerial system located in the Halfway Bush district, Dunedin, NZ, on 11 May 2024. The data are FFT amplitudes for 1025 bin widths of ~23 Hz, covering the range from 0 to 24000 Hz. The time resolution is 4 s, and the file lasts a day. Swa20240511 is a fluxgate magnetometer data file from the Otago Univeristy Swampoy Summit sObservatory, Dunedin, on 11 May 2024 with time and 3 components Bx,By, Bz. The time resolution is 1 s, and the file lasts a day.

本归档文件包含两个文本文件。其中，Hires_HWB_UWB20240511.txt为一套甚低频宽带数据集，采集自位于新西兰达尼丁半壁山区的奥塔哥大学天线系统，采集时间为2024年5月11日。该数据集包含1025个频点的快速傅里叶变换（FFT）幅值，每个频点带宽约23 Hz，覆盖频率范围为0至24000 Hz，时间分辨率为4秒，单文件完整时长为一整天。Swa20240511为奥塔哥大学斯瓦莫伊山顶天文台的磁通门磁力计数据文件，采集于2024年5月11日的达尼丁地区，文件包含时间信息与Bx、By、Bz三个磁场分量数据，时间分辨率为1秒，单文件完整时长为一整天。
