Data Search and Download
The WOUDC data archive can be searched by data category: there are six ozone data categories and three ultraviolet (UV) radiation data categories. The ozone datasets for total column ozone include total ozone and total ozone observations and the vertical ozone profile includes lidar, ozonesonde, Umkehr N-value and C-Umkehr. The UV datasets for UV irradiance include broadband, multiband and spectral.
To search and download data, select the dataset and observation time period. Optionally, draw your map extent of interest and then hit search. All available data for that time period will be displayed.
