As one of important approaches to obtain the ozone concentration profile from the surface to the upper stratosphere,ozone sondes need to be tested before launching to evaluate its performance and to make sure that high-quality observational data can be obtained during the flight.The detailed information about the ground-based test system for electrochemical concentration cells of ozone sondes is described.The system is composed of the test unit,data collecting module,and software used for the data processing,which is used to test the background current and response time of the electrochemical concentration cells.The test unit can provide air containing different ozone concentrations deployed to test the detecting performance of a cell.The test results are transferred to a computer by the data collecting module.The software can store and process the collected data as well as extract the background current and response time automatically.The application results show that the test system has high accuracy and stable performance and thus can be used for the ground-based ozone sonde check for conventional observations in China in future.
