Total O3 columns at polar regions: TOMCAT/SLIMCAT passive and active tracers and merged SAOZ-MSR2 dataset

Passive and active total ozone columns simulated by the chemical transport model TOMCAT/SLIMCAT (Chipperfield, 1999) and the merged dataset of total ozone from Système d'Analyse par Observation Zénithale (SAOZ, Pommereau and Goutail, 1988) ground-based instruments and Multi-Sensor Reanalysis (MSR2, van der A et al., 2010, 2015) for the polar stations described in the Table here below. Table. Arctic and Antarctic stations included in the study: station name and ID, latitude, longitude and measurement periods of SAOZ and MSR2 datasets. <table> <tbody> <tr> <td> Station (ID) </td> <td> Lat, Lon </td> <td> SAOZ dataset </td> <td> MSR2 dataset </td> </tr> <tr> <td> Eureka, Nunavut (EU) </td> <td> 80.1°N, 86.4°W </td> <td> 2005-2020 </td> <td> 1990-2022 </td> </tr> <tr> <td> Ny-Alesund, Svalbard (NY) </td> <td> 78.9°N, 11.9° E </td> <td> 1991-2022 </td> <td> 1990-2022 </td> </tr> <tr> <td> Thule, Greenland (TH) </td> <td> 76.5°N, 68.8°W </td> <td> 1999-2003, 2005-2016 </td> <td> 1990-2022 </td> </tr> <tr> <td> Scoresbysund, Greenland (SC) </td> <td> 70.5°N, 22.0°W </td> <td> 1991-2017, 2019-2022 </td> <td> 1990-2022 </td> </tr> <tr> <td> Sodankyla, Finland (SK) </td> <td> 67.4°N, 26.6° E </td> <td> 1991-2022 </td> <td> 1990-2022 </td> </tr> <tr> <td> Sondre Stromfjord, Greenland (SS) </td> <td> 67.0°N, 50.6°W </td> <td> 2018-2022 </td> <td> 1990-2022 </td> </tr> <tr> <td> Zhigansk, Russia (ZH) </td> <td> 66.8°N, 123.4° E </td> <td> 1992-2013 </td> <td> 1990-2022 </td> </tr> <tr> <td> Salekhard, Russia (SA) </td> <td> 66.5°N, 66.7°E </td> <td> 2002-2016 </td> <td> 1990-2022 </td> </tr> <tr> <td> Marambio, Antarctica (MB) </td> <td> 64.2°S, 56.7°W </td> <td> - </td> <td> 1989-2021 </td> </tr> <tr> <td> Dumont d’Urville, Antarctica (DD) </td> <td> 66.7°S, 140.0°E </td> <td> 1989-2021 </td> <td> 1989-2021 </td> </tr> <tr> <td> Rothera, Antarctica (RO) </td> <td> 67.6°S, 68.1°W </td> <td> 2007-2021 </td> <td> 1989-2021 </td> </tr> <tr> <td> Syowa, Antarctica (SW) </td> <td> 69.0°S, 39.6°E </td> <td> - </td> <td> 1989-2021 </td> </tr> <tr> <td> Neumayer, Antarctica (NM) </td> <td> 70.7°S, 8.3°W </td> <td> - </td> <td> 1989-2021 </td> </tr> <tr> <td> Terra Nova, Antarctica (TN) </td> <td> 74.8°S, 164.5°E </td> <td> - </td> <td> 1989-2021 </td> </tr> <tr> <td> Concordia, Antarctica (DO) </td> <td> 75.1°S, 123.4°E </td> <td> 2007-2021 </td> <td> 1989-2021 </td> </tr> <tr> <td> Halley, Antarctica (HB) </td> <td> 75.6°S, 26.8°W </td> <td> - </td> <td> 1989-2021 </td> </tr> </tbody> </table>   Each file corresponds to the whole winter time data set of the station identified by its ID: O3_PassActSLIMCAT_CompositeMSR2SAOZ_ID.txt 1st column: Year 2nd column: Day of Year (DoY) 3rd column: Passive ozone column (without chemistry) modelled by TOMCAT/SLIMCAT (O3pasS). 4th column: Active ozone column (with full chemistry) modelled by TOMCAT/SLIMCAT (O3actS). 5th column: merged data from SAOZ observations and MSR2 (O3comp) Passive and active tracers of SLIMCAT were normalized to O3comp data in the beginning of the winter. NaN is used when there is no observation either from SAOZ instrument or MSR2 dataset or from the model.   References Chipperfield, M.
