The influence of the buffers was revealed as a result of new, direct measurements of the ozonesonde pump flow rate efficiency made in an environmental chamber using an oil bubble flowmeter developed at National Oceanic and Atmospheric Administration/Climate Monitoring and Diagnostics Laboratory (NOAA/CMDL). The new flow rate measurements give pump efficiency correction factors that are 2 and 15% greater at 100 and 5 hPa, respectively, than those used in currently recommended procedures. Profile measurements using ozonesondes with differing ECC sensor solutions, on dual-sonde balloons and experiments in a simulation chamber, show that the impact of the buffers is most pronounced above the ozone partial pressure maximum. The effect is about a 10-15% overmeasurement of ozone at an altitude of 30 km. Careful consideration must be given to the combination of the sensing solution composition and pump efficiency correction if representative ozone profiles are to be obtained from ozonesonde measurements. 000033290 536__ $$0G:(DE-Juel1)FUEK257$$2G:(DE-HGF)$$aChemie und Dynamik der Geo-Biosphäre$$cU01$$x0 000033290 588__ $$aDataset connected to Web of Science 000033290 650_7 $$2WoSType$$aJ 000033290 65320 $$2Author$$aozonesonde 000033290 65320 $$2Author$$aiodometric method 000033290 65320 $$2Author$$aintercomparison 000033290 7001_ $$0P:(DE-HGF)0$$aOltmans, S.$$b1 000033290 7001_ $$0P:(DE-HGF)0$$aVömel, H.$$b2 000033290 7001_ $$0P:(DE-Juel1)16203$$aSmit, A.
