Partial and total ozone column measurements at Lauder (45S, 170E) from FTIR, Dobson, UV2, lidar, ozonesonde, microwave radiometer

Description

This data set contains netCDF files of the total and partial columns of FTIR, Dobson, UV2, lidar, ozonesonde, and microwave radiometer observations. They represent measurement coincidences of each measurement with FTIR taken within a specific time window (specified in the description of each file). The technique for the creation of the measurement pairs of the total and partial columns is explained in the following publication: *Intercomparison of long-term ground-based measurements of tropospheric and stratospheric ozone at Lauder, New Zealand (45S)*
*Robin Björklund, Corinne Vigouroux, Peter Effertz, Omaira Garcia, Alex Geddes, James Hannigan, Koji Miyagawa, Michael Kotkamp, Bavo Langerock, Gerald Nedoluha, Ivan Ortega, Irina Petropavlovskikh, Deniz Poyraz, Richard Querel, John Robinson, Hisako Shiona, Dan Smale, Penny Smale, Roeland Van Malderen, and Martine De Mazière.* *https://doi.org/10.5194/egusphere-2023-2668* The files contain the corresponding measurement times as well as the column density values for both FTIR and the measurement that is considered simultaneously. These are either total column values (file name contains 'TC') or partial column values (file name contains 'PC'). For the Umkehr, microwave radiometer, lidar, and ozonesonde measurements the profiles have been regridded, smoothed, and substituted with another prior (when relevant), where all these steps are included in the variables of the partial columns. In the bias and drift analysis Björklund et al. 2024 use: ### FTIR vs lidar *FTIR_measurement_pc_X_on_FTIR* vs *LIDAR_measurement_smooth_with_FTIR_avk_pc_X_on_FTIR* ### FTIR vs Dobson *FTIR_column* vs *DOBSON_column* ### FTIR vs UV2 *FTIR_column* vs *UV2_column* ### FTIR vs MWR *FTIR_measurement_pc_X_on_FTIR* vs *GB_with_FTIR_prior_smooth_with_FTIR_avk_pc_X_on_FTIR* ### FTIR vs ozonesonde *FTIR_measurement_pc_X_on_FTIR* vs *O3SONDE_measurement_smooth_with_FTIR_avk_pc_X_on_FTIR* ### FTIR vs Umkehr *FTIR_measurement_smooth_with_UMKEHR_avk_pc_X_on_UMKEHR* vs *UMKEHR_with_FTIR_prior_pc_X_on_UMKEHR* In the variable names the *X* represents the number of the different partial columns as specified in the description of the files separately. ### Source locations for individual datasets Information about each data set can be found at their individual source location: Current public data for the FTIR, lidar, MWR, and Umkehr can be found at [NDACC](https://ndacc.larc.nasa.gov/data). The FTIR data will be updated here with the new strategy explained in the Bjorklund et al. 2024. NOAA Dobson Total Column Ozone measurements can also be found on the [NOAA GML FTP website](https://gml.noaa.gov/aftp/data/ozwv/Dobson/), at [WOUDC](https://woudc.org/). Likewise the Monthly Mean optimized/homogenized Umkher profiles can be found on the [NOAA GML FTP](https://gml.noaa.gov/aftp/ozwv/Dobson/AC4/Umkehr/Optimized). Ozonesondes: The homogenized Lauder ozonesonde time series are available at the [HEGIFTOM ftp-server](https://hegiftom.meteo.be/datasets/ozonesondes).
