Electron concentration profiles calculated using different plasma chemical models during solar X-ray flares

The files contain electron concentration <em>Ne</em> profiles during solar X-ray flares that occurred on 24-25 October 2013 and 9-11 June 2014. The altitude range is 50-90 km. Values of electron concentration were calculated using four-, five- and eight-component models of the ionospheric D-region. Results are obtained on four VLF paths: from European transmitters ICV, FTA, GQD, DHO to Mikhnevo geophysical observatory (55°N 38°E). The data is presented as MATLAB files. Each .mat file contains data and variable "description" with data's structure information.本数据集包含2013年10月24日至25日、2014年6月9日至11日发生的太阳X射线耀斑期间的电子浓度（electron concentration，常用符号Ne）廓线，观测高度范围为50~90千米。电子浓度数值通过电离层D区（ionospheric D-region）的四分量、五分量及八分量模型计算得到。研究结果基于4条甚低频（Very Low Frequency, VLF）传播路径获得，路径为从欧洲发射台ICV、FTA、GQD、DHO延伸至米赫涅沃地球物理观测站（地理坐标：55°N，38°E）。数据集以MATLAB文件格式存储，每个.mat文件均包含实测数据与用于说明数据结构的变量"description"。
