报道了用改进的光碎裂双光子激光诱导荧光仪(PF-TP-LIF)测量NO和NO2的方法。现有证据表明，这些变化大大减少了不稳定的NOY物种的壁分解。与美国宇航局1991年PEM-WEST A计划报告的结果形成鲜明对比的是，(NO2)meas/(NO2)Calc的中位值为3.36，而PEM-热带A的观测结果为0.93。这表明，远距离上层对流层NO-NO2数据首次显示出与目前的光化学机制高度一致。
Measurements of NO and NO2 are reported using a highly modified photofragmentation two‐photon laser‐induced fluorescence (PF‐TP‐LIF) instrument. Available evidence suggests that the changes made substantially reduced wall decomposition of labile NOy species. In sharp contrast to the results reported from NASA's 1991 PEM‐West A program where the median value for the ratio (NO2)meas/(NO2)calc was 3.36, the PEM‐Tropics A observations produced a value for this ratio of 0.93. This represents the first time that remote upper tropospheric NO‐NO2 data have shown a high degree of correspondence with current photochemical mechanisms.
