Electrochemical concentration cell ozonesonde performance evaluation during STOIC 1989

摘要: Electrochemical concentration cell (ECC) ozonesondes flown by NOAA and NASA Wallops Flight Facility (WFF) personnel during the Stratospheric Ozone Intercomparison Campaign (STOIC) conducted at Jet Propulsion Laboratory's Table Mountain Facility, Wrightwood, California, July 21 to August 1, 1989, exhibited highly similar ozone measurement precisions accuracies even though considerably different methods were used two research groups in preparing instruments for use calibrating instruments. The data as well obtained past showed range from about ±3 ±12% troposphere, remain relatively constant ±3% stratosphere 10 mbar, then decrease ±10% 4-mbar pressure altitude. Corresponding individual ozonesonde soundings estimated be ±6% near ground, −7 17% high troposphere where concentrations are low, increase ±5% low so an altitude of mbar (∼32 km), −14 6% 4 (∼38 km) again low. measurements also made STOIC with ground-based lidars a microwave radiometer that will future sites Network Detection Change (NDSC). ECC observations provided useful comparison evaluating performance lidar
