Performance Characteristics of High-Altitude ECC Ozonesondes

摘要: Tests and instrument modifications were made to extend the operating range of ECC (electrochemical concentration cell) ozonesondes 40-km (3-mb) altitudes where photochemical theory predicts significant ozone depletion by chlorofluorocarbons. Heights 40 km can be routinely attained new, lightweight, plastic balloons. Six sondes flown simultaneously at Palestine, Texas, 21 march 1984 during a NASA-sponsored Balloon Intercomparison Campaign exhibited high degree precision in measurement ozone. Comparison data with results simultaneous soundings UV photometers indicated good agreement 30 km. yielded progressively lower values higher altitudes.
