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": "\u8ad6\u6587", "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": [{"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", "download_preview_message": "", "file_order": 0, "filename": "1-s2.0-S2211379719321163-main.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "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"], "permalink_uri": "http://hdl.handle.net/20.500.12000/48645", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2021-06-28"}, "publish_date": "2021-06-28", "publish_status": "0", "recid": "2011606", "relation": {}, "relation_version_is_last": true, "title": ["Color analysis based on the color indices of lightning channels obtained from a digital photograph"], "weko_shared_id": -1}
