We used color-magnitude diagrams (CMDs) modified from the traditional CMDs employed in astronomical photometry, (B-G) versus (G-R) color-color diagrams (CCDs), two-dimensional (2D) color-index images for the color indices B-G,B-R, and G-R, and a 2D brightness image to analyze the colors and brightness of the lightning channels. The CMDs and CCDs for the lightning leader channels showed that the intensity of B-band and R-band light from those channels exceeds that of the G-band light. The 2D color-index images for B-G,B-R, and G-R and the 2D brightness image indicate spatial variations in the lightning channels. The spatial variabilities of the 2D color indices and 2D brightness indicate that the intensity of the B-band light exceeds that of the G- and R-band light around a bright channel with a high electric current (i.e., the plasma is highly ionized).","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"Springer"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/48645"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0947-7047"},{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1862-0760"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Ionics"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2019-12","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"15"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.1016/j.rinp.2019.102662"}},{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.1016/j.rinp.2019.102662"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"1-s2.0-S2211379719321163-main.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2011606/files/1-s2.0-S2211379719321163-main.pdf"},"version_id":"ec814dd0-9121-4bea-a186-d31e32fe9eb9"}]},"item_title":"Color analysis based on the color indices of lightning channels obtained from a digital photograph","item_type_id":"15","owner":"1","path":["1642838338003","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-06-28"},"publish_date":"2021-06-28","publish_status":"0","recid":"2011606","relation_version_is_last":true,"title":["Color analysis based on the color indices of lightning channels obtained from a digital photograph"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-08-03T05:29:06.752187+00:00"}
