World Ozone and Ultraviolet Radiation Data Centre

Digital technologies don’t just exist as nifty gadgets; data are technologies themselves, while also acting as the foundational component of most other technologies. This is particularly true when it comes to ecological monitoring. The World Ozone and Ultraviolet Radiation Data Centre falls under the jurisdiction and is operated by Environment and Climate Change Canada. Commonly known as the WOUDC, it is one of six World Data Centres which are part of the Global Atmosphere Watch Programme of the World Meteorological Organization. WOUDC’s roots go back to 1960 when the World Ozone Data Center was founded in Canada. Then, in 1992, ultraviolet radiation information was added, changing the WODC to the WOUDC. In 2015, all of the data moved to an online platform and has become much more accessible to the public since that transition, with all records available for public search and download. Data is collected by 500 registered monitoring stations, which can be used as a filter for the searchable data. The data contain the following information:  total column ozone, vertical profile data from lidar measurements, ozonesonde flights, the Umkehr technique, broadband, multiband, and high-resolution spectral data. All of this information is incredibly useful for monitoring atmospheric conditions for weather predictions, research on atmospheric health, and security and transportation purposes.
