Year-to-Date Ozonesonde Graphs

This section contains plots of the time-altitude cross-section of the ozone partial pressure measured by ECC ozonesondes at 10 Canadian stations. Ozone partial pressure is given in nanobars. The actual data are available (typically, with one month delay) from the The World Ozone and Ultraviolet Radiation Data Center (WOUDC).

Stations are ordered from south to north.

Graphs from previous years, and from other stations contributing to the WOUDC can be found at
