摘　　要：Ozonesondes are widely used to obtain ozone concentration profiles from the surface to the upper atmosphere.A kind of double-cell ozonesonde has been developed at the Institute of Atmospheric Physics （IAP）,Chinese Academy of Sciences （named the ＂IAP ozonesonde＂） based on previous experience over the past 20 years of developing the singlecell GPSO3 ozonesonde.The IAP ozonesonde is of the Electrochemical Concentration Cell （ECC） type.A detailed description of the IAP ozonesonde is firstly provided in the present paper,followed by a presentation of results from a series of launches carried out to evaluate its performance.The analysis involved comparing its observations with measurements from the GPSO3 and ECC ozonesondes （Model type ENSCI-Z） as well as a Brewer spectrophotometer.The results showed that the IAP ozonesonde is a vast improvement over the GPSO3 ozonesonde,able to capture vertical ozone structures very well and in good agreement with ECC ozonesonde measurements.The average difference in the ozone partial pressure between the IAP and ECC ozonesondes was 0.3 mPa from the surface to 2.5 km,close to zero from 2.5 to 9 km and generally less than 1 mPa for layers higher than 9 km.The apparent deviation is likely caused by a decreasing pump flow rate in the IAP ozonesonde which needs further improvement.The total ozone amounts measured by the IAP ozonesonde profiles were highly comparable with the Brewer data with a relative difference of 6％.The development of the IAP ozonesonde and its strong performance will surely accelerate the process of conventional observations of ozone profiles over China in the near future as well as provide more data for ozone research in general.Ozonesondes are widely used to obtain ozone concentration profiles from the surface to the upper atmosphere.A kind of double-cell ozonesonde has been developed at the Institute of Atmospheric Physics （IAP）,Chinese Academy of Sciences （named the ＂IAP ozonesonde＂） based on previous experience over the past 20 years of developing the singlecell GPSO3 ozonesonde.The IAP ozonesonde is of the Electrochemical Concentration Cell （ECC） type.A detailed description of the IAP ozonesonde is firstly provided in the present paper,followed by a presentation of results from a series of launches carried out to evaluate its performance.The analysis involved comparing its observations with measurements from the GPSO3 and ECC ozonesondes （Model type ENSCI-Z） as well as a Brewer spectrophotometer.The results showed that the IAP ozonesonde is a vast improvement over the GPSO3 ozonesonde,able to capture vertical ozone structures very well and in good agreement with ECC ozonesonde measurements.The average difference in the ozone partial pressure between the IAP and ECC ozonesondes was 0.3 mPa from the surface to 2.5 km,close to zero from 2.5 to 9 km and generally less than 1 mPa for layers higher than 9 km.The apparent deviation is likely caused by a decreasing pump flow rate in the IAP ozonesonde which needs further improvement.The total ozone amounts measured by the IAP ozonesonde profiles were highly comparable with the Brewer data with a relative difference of 6％.The development of the IAP ozonesonde and its strong performance will surely accelerate the process of conventional observations of ozone profiles over China in the near future as well as provide more data for ozone research in general.
