SAFARI 2000 JRA AEROCOMMANDER TRACE GAS, AEROSOL, AND CCN DATA, DRY SEASON 2000

As part of the 3rd Intensive Campaign of SAFARI 2000, the South African Weather Bureau Aerocommander, JRA, flew 19 missions, for a total of 28 separate flights conducted between August 15th and September 7th, 2000. JRA worked closely with the other Aerocommander, JRA, and was dedicated to the measurement of trace gas and aerosol properties. A suite of trace analyzers (for O3, SO2, CO and NO), laser aerosol probes and atmospheric probes were present for all flights. Other instruments and sampling units present for some of the flights included, a nephelometer (Elias), CO flasks (Novelli) for MOPITT validation purposes, and VOC canisters for the collection and characterization of volatile organic compounds present over various land surface types.

作为2000年SAFARI科考计划第三次密集科考活动的组成部分，南非气象局所属的空中指挥官（Aerocommander）机型JRA执行了19项任务，于2000年8月15日至9月7日间累计完成28次独立飞行。该机型JRA与另一架空中指挥官（Aerocommander）机型JRA密切协作，专注于痕量气体（trace gas）与气溶胶特性的测量工作。所有飞行任务均标配一套痕量气体分析仪（用于检测臭氧O3、二氧化硫SO2、一氧化碳CO与一氧化氮NO）、激光气溶胶探头及大气探测探头。部分飞行任务额外搭载了其他仪器与采样单元：包括Elias型浊度计（nephelometer）、用于MOPITT校准验证的Novelli品牌一氧化碳采样瓶，以及用于采集并表征不同陆地表面类型上空挥发性有机化合物（volatile organic compounds, VOC）的采样罐。
