Experimental data for the manuscript "Whistler echo trains triggered by energetic winter lightning": part 1

Two-component magnetic field data recorded at the high latitude receiving station Kannuslehto operated by the Sodankyla Geophysical Observatory in Finland (67.7°N, 26.3°E). The dataset consists of 4 files, each of them contains the 1-hour long continuous record of magnetic field fluctuations measured by two orthogonal magnetic loops. The data originates from January 3, 2017 00:00-04:00 UTC.本数据集为芬兰索丹屈拉地球物理天文台（Sodankyla Geophysical Observatory）运维的高纬度接收站卡努斯莱赫托（Kannuslehto，67.7°N，26.3°E）所记录的双分量磁场数据。该数据集包含4个文件，每个文件均存储由两个正交磁环采集的1小时连续磁场扰动记录。数据采集时段为2017年1月3日00:00-04:00协调世界时（UTC）。
