Bharati falls in and out of the ‘ozone hole’ over Antarctica due to the dynamics of the polar vortex, which results in drastic variability. Results show that while both the satellites captured the annual variability in the TCOs, OMI overestimates it by 66.3 DU, i.e. approximately 33% (range: 2.4 to 189.7 DU), while MLS overestimates it by 33.8 DU, i.e. approximately 16% (range: 95.9 to 8.6 DU) compared to the ozonesondes. MLS reproduced the vertical profile variation and peak heights of the ozone layer but overestimated the concentrations compared to the ozonesondes. The overestimation varied with season, with the largest difference during the ozone depletion season in September-October-November (SON: ~40%). MLS and ozonesondes linear fits showed that although the datasets showed good correlation (R2 = 0.97, P < 0.001), there was a significant positive bias in the MLS observations (slope = 1.32 ± 0.38; intercept = 0.55 ± 0.05). This overestimation by MLS also results in an overestimation in the heating rates over Bharati, with the difference peaking in SON at 0.4 ± 0.2 K day−1.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2020.100547"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2020.100547","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hulswar, Shrivardhan","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70393","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Soni, V.K.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70394","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sapate, J.P.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70395","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"More, R.S.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70396","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mahajan, Anoop S.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70397","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ozone depletion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Validation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctic ozone","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MLS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ozonesonde","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Validation of satellite retrieved ozone profiles using in-situ ozonesonde observations over the Indian Antarctic station, Bharati","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Validation of satellite retrieved ozone profiles using in-situ ozonesonde observations over the Indian Antarctic station, Bharati"},{"subitem_title":"Validation of satellite retrieved ozone profiles using in-situ ozonesonde observations over the Indian Antarctic station, Bharati","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"26","path":["2025"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-10-08"},"publish_date":"2020-10-08","publish_status":"0","recid":"16059","relation_version_is_last":true,"title":["Validation of satellite retrieved ozone profiles using in-situ ozonesonde observations over the Indian Antarctic station, Bharati"],"weko_creator_id":"26","weko_shared_id":-1},"updated":"2023-07-25T13:00:09.915340+00:00"}
