It is found that in existing projection transforms, pixel intensity has not been corrected at all, and an assumption has been adopted that aurora luminosity is confined in a thin layer of the ionosphere. Under this assumption, namely, that aurora appears in a thin layer of the ionosphere, an expression for pixel intensity correction in a projection of an all-sky auroral image onto the geomagnetic/geographic coordinates is explicitly derived, in which the visual enhancement due to the all-sky imaging geometry and the extinction due to the atmospheric absorption are concerned. The correction may be represented by a diagonal matrix, and should be added to the existing algorithm.", "subitem_description_type": "Other"}]}, "item_1_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15094/00004237", "subitem_identifier_reg_type": "JaLC"}]}, "item_1_publisher_22": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "National Institute of Polar Research"}]}, "item_1_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10756224", "subitem_source_identifier_type": "NCID"}]}, "item_1_text_10": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Polar Research Institute of China/Polar Research Institute of China/National Institute of Polar Research"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "1998-01-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000035940.pdf", "filesize": [{"value": "686.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 686300.0, "url": {"label": "KJ00000035940", "url": "https://nipr.repo.nii.ac.jp/record/4237/files/KJ00000035940.pdf"}, "version_id": "3b8f689a-6fb3-41ce-a47b-91139ad681a6"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Study on pixel intensity correction in projection transform of an all-sky auroral image", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Study on pixel intensity correction in projection transform of an all-sky auroral image"}]}, "item_type_id": "1", "owner": "4", "path": ["547"], "permalink_uri": "https://doi.org/10.15094/00004237", "pubdate": {"attribute_name": "公開日", "attribute_value": "1998-01-01"}, "publish_date": "1998-01-01", "publish_status": "0", "recid": "4237", "relation": {}, "relation_version_is_last": true, "title": ["Study on pixel intensity correction in projection transform of an all-sky auroral image"], "weko_shared_id": 4}
