The observational data gap centred at the pole is filled via interpolation as described in the retrieval report: <a href=\"https://icdc.cen.uni-hamburg.de/fileadmin/user_upload/ESA_Sea-Ice-ECV_Phase2/SICCI_Phase2_SIV-Retrieval_Report_v02.pdf\">https://icdc.cen.uni-hamburg.de/fileadmin/user_upload/ESA_Sea-Ice-ECV_Phase2/SICCI_Phase2_SIV-Retrieval_Report_v02.pdf</a>. This report does also describe how uncertainties are estimated, and how the Envisat data are bias-corrected with respect to the CryoSat-2 data. The NSIDC sector Arctic Ocean can be viewed, e.g. from the following netCDF file <a href=\"https://icdc.cen.uni-hamburg.de/fileadmin/user_upload/icdc_Bilder/asi_sic/NSIDC-25km-grid__Arctic-SeaIceOutlook_region_masks__GridCellArea__UHAM-ICDC__fv0.01.nc\">https://icdc.cen.uni-hamburg.de/fileadmin/user_upload/icdc_Bilder/asi_sic/NSIDC-25km-grid__Arctic-SeaIceOutlook_region_masks__GridCellArea__UHAM-ICDC__fv0.01.nc</a> or <a href=\"https://www.arcus.org/files/page/documents/28201/sio_mask.nc\">https://www.arcus.org/files/page/documents/28201/sio_mask.nc</a>.</p>\n\n<p><strong>Table of contents:</strong> sea ice volume; sea ice volume retrieval error</p>\n\n<p><strong>Technical Info:</strong> dimension: 105 rows resulting from 15 winters times seven months (October through April); temporalExtent_startDate: 2002-10-01; temporalExtent_endDate: 2017-04-30; temporalResolution: monthly; spatialResolution: none; spatialResolutionUnit: none; horizontalResolutionXdirection: none; horizontalResolutionXdirectionUnit: none; horizontalResolutionYdirection: none; horizontalResolutionYdirectionUnit: none; verticalResolution: none; verticalResolutionUnit: none; verticalStart: none; verticalEnd: none; instrumentName: SIRAL, RA-2; instrumentType: radar altimeter; instrumentLocation: Environmental Satellite (Envisat), CryoSat-2; instrumentProvider: various, ESA&nbsp;</p>\n\n<p><strong>Methods:</strong> <a href=\"https://icdc.cen.uni-hamburg.de/fileadmin/user_upload/ESA_Sea-Ice-ECV_Phase2/SICCI_Phase2_SIV-Retrieval_Report_v02.pdf\">https://icdc.cen.uni-hamburg.de/fileadmin/user_upload/ESA_Sea-Ice-ECV_Phase2/SICCI_Phase2_SIV-Retrieval_Report_v02.pdf</a>.</p>\n\n<p><strong>Units:</strong> km<sup>3</sup>; km<sup>3</sup></p>\n\n<p><strong>geoLocations: </strong>westBoundLongitude: -180.0 degrees East; eastBoundLongitude: 180.0 degrees East; southBoundLatitude: 60.0 degrees North; northBoundLatitude: 90.0 degrees North; geoLocationPlace: Arctic Ocean</p>\n\n<p><strong>Size:</strong> 1 file with three semikolon-separated columns; 105 rows</p>\n\n<p><strong>Format:</strong> ascii text</p>\n\n<p><strong>DataSources: </strong></p>\n\n<p><a href=\"http://catalogue.ceda.ac.uk/uuid/f4c34f4f0f1d4d0da06d771f6972f180\">http://catalogue.ceda.ac.uk/uuid/f4c34f4f0f1d4d0da06d771f6972f180</a> (last accessed: 2018-05-20)</p>\n\n<p><a href=\"http://catalogue.ceda.ac.uk/uuid/ff79d140824f42dd92b204b4f1e9e7c2\">http://catalogue.ceda.ac.uk/uuid/ff79d140824f42dd92b204b4f1e9e7c2</a> (last accessed: 2018-05-20)</p>\n\n<p><a href=\"https://doi.org/10.5285/f17f146a31b14dfd960cde0874236ee5\">https://doi.org/10.5285/f17f146a31b14dfd960cde0874236ee5</a> (last accessed: 2018-05-20)</p>\n\n<p><a href=\"https://doi.org/10.15770/EUM_SAF_OSI_0008\">https://doi.org/10.15770/EUM_SAF_OSI_0008</a> (last accessed: 2018-05-20)</p>\n\n<p><strong>Contact:</strong> <a href=\"mailto:stefan.kern@uni-hamburg.de\">stefan.kern (at) uni-hamburg.de</a></p>\n\n<p><strong>Web page:</strong> <a href=\"https://icdc.cen.uni-hamburg.de/en/esa-cci-sea-ice-ecv0.html\">https://icdc.cen.uni-hamburg.de/en/esa-cci-sea-ice-ecv0.html</a></p>","distribution":[{"@type":"DataDownload","contentUrl":"https://www.fdr.uni-hamburg.de/api/files/5290b4a1-ef1f-4999-8b9b-afce64d7b9f9/ESA-SICCI2_ICDC__SeaIceVolumeTimeseries__north_ao_v02_fv0.02.xml","encodingFormat":"xml"},{"@type":"DataDownload","contentUrl":"https://www.fdr.uni-hamburg.de/api/files/5290b4a1-ef1f-4999-8b9b-afce64d7b9f9/ESA-SICCI2_ICDC__SeaIceVolumeTimeseries__north_ao_v2.0_fv0.02.txt","encodingFormat":"txt"}],"identifier":"http://doi.org/10.25592/uhhfdm.8508","inLanguage":{"@type":"Language","alternateName":"eng","name":"English"},"keywords":["Climate","Marine cryosphere","Arctic ocean","Sea ice","Satellite remote sensing","Sea ice volume","ESA-CCI","SICCI","ICDC"],"license":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"ESA-SICCI2 Arctic Ocean Winter-Time Monthly Sea-Ice Volume Timeseries","url":"https://www.fdr.uni-hamburg.de/record/8508","version":"2.0_fv0.02"}
