      abstract     = {[1] Since 1996, quality assurance experiments of
                      electrochemical concentration cell (ECC) ozonesondes of two
                      different model types (SPC-6A and ENSCI-Z) have been
                      conducted in the environmental simulation facility at the
                      Research Centre Juelich within the framework of the Juelich
                      Ozone Sonde Intercomparison Experiment (JOSIE). The
                      experiments have shown that the performance characteristics
                      of the two ECC-sonde types can be significantly different,
                      even when operated under the same conditions. Particularly
                      above 20 km the ENSCI-Z sonde tends to measure $5-10\%$ more
                      ozone than the SPC-6A sonde. Below 20 km the differences are
                      $5\%$ or less, but appear to show some differences with year
                      of manufacture. There is a significant difference in the
                      ozone readings when sondes of the same type are operated
                      with different cathode sensing solutions. Testing the most
                      commonly used sensing solutions showed that for each
                      ECC-manufacturer type the use of $1.0\%$ KI and full buffer
                      gives $5\%$ larger ozone values compared with the use of
                      $0.5\%$ KI and half buffer, and as much as $10\%$ larger
                      values compared with $2.0\%$ KI and no buffer. For ozone
                      sounding stations performing long term measurements this
                      means that changing the sensing solution type or ECC-sonde
                      type can easily introduce a change of +/- $5\%$ or more in
                      their records, affecting determination of ozone trends.
                      Standardization of operating procedures for ECC-sondes
                      yields a precision better than $+/-(3-5)\%$ and an accuracy
                      of about $+/-(5-10)\%$ up to 30 km altitude.},
