Through the analysis of variation in the electric field (E-field) signal of lightning during the actual propagation, it was found that (1) the attenuation of lightning E-field signal with distance can be fairly well described by the power-law relationship E = ar\u2212b, and the attenuation index is b = 1.02 (for IC) and b = 1.13 (for CG); (2) under the situation of the same propagation path, the IC pulses experience less attenuation than CG pulses; and (3) through the comparison with simulations, it can be seen that the attenuation of lightning E-field pulse is affected by the conductivity of the ground surface, and according to the attenuation factor of lightning E-field strength, it can be inferred that the conductivity in the Jianghuai area ranges between 0.005 S\/m and 0.01 S\/m, which is in good agreement with the measured conductivity in this area. Our results suggest that lightning radiation could provide a feasible means for remotely sensing the ground conductivity.<\/jats:p>","DOI":"10.3390\/rs14071672","type":"journal-article","created":{"date-parts":[[2022,3,30]],"date-time":"2022-03-30T21:28:39Z","timestamp":1648675719000},"page":"1672","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Characterizing Pulse Attenuation of Intra-Cloud and Cloud-to-Ground Lightning with E-Field Signal Measured at Multiple Stations"],"prefix":"10.3390","volume":"14","author":[{"given":"Wenwei","family":"Wang","sequence":"first","affiliation":[{"name":"School of Earth and Space Sciences, University of Science and Technology of China, Hefei 230026, China"}]},{"given":"Baoyou","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Earth and Space Sciences, University of Science and Technology of China, Hefei 230026, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,30]]},"reference":[{"key":"ref_1","first-page":"1203","article-title":"The Propagation of Radio Waves over the Surface of the Earth and in the Upper Atmosphere","volume":"25","author":"Norton","year":"1936","journal-title":"IEEE"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1173","DOI":"10.1109\/PROC.1986.13610","article-title":"Propagation effects for electromagnetic pulse transmission","volume":"74","author":"Wait","year":"1986","journal-title":"Proc.
