The ozone destruction filter eliminates ozone generated during testing, but the ASOPOS panel (Assessment of Standard Operating Procedures for Ozonesondes) recommends the use of purified, ozone-free air instead of the destruction filter. For more information, see GAW Report 201 and Performance review literature.
