[1]我们目前的验证研究MLS版本2.2上层对流层和平流层臭氧廓线使用臭氧探空仪和激光雷达数据以及气候数据。全球60多个臭氧探测站和三个激光雷达站的臭氧测量结果与MLS数据进行了比较。MLS平流层150 ~ 3 hPa臭氧资料与臭氧探空仪观测值吻合较好，与全球平均值的吻合度在8%以内。215百帕的微波着陆系统值与臭氧探测仪相比偏高，在中高纬度地区偏高约20%，尽管在这一高度区域有很大的变化。MLS和地面激光雷达测量从莫纳罗亚，夏威夷，从桌山设施，加州，和从天文台上普罗旺斯，法国之间的比较，给出了非常好的协议，在类似的5%，平流层值。MLS和桌山设施对流层臭氧激光雷达之间的比较表明，MLS数据偏高，在215 hPa的30%左右，与臭氧探空仪数据所表明的一致。我们得到更好的全球平均协议之间的MLS和臭氧探空仪部分列值下降到215百帕，虽然在低到中纬度的平均MLS值高于臭氧探空仪值高达百分之几。MLS v2.2的臭氧数据与臭氧探测仪和激光雷达测量的数据比MLS v1.5的数据更一致。MLS热带数据显示，在对流层上部的波一纵向模式，与臭氧探测仪的平均分布相似。MLS在6月至11月期间还在热带太平洋观测到对流层上层臭氧值较高。
[1] We present validation studies of MLS version 2.2 upper tropospheric and stratospheric ozone profiles using ozonesonde and lidar data as well as climatological data. Ozone measurements from over 60 ozonesonde stations worldwide and three lidar stations are compared with coincident MLS data. The MLS ozone stratospheric data between 150 and 3 hPa agree well with ozonesonde measurements, within 8% for the global average. MLS values at 215 hPa are biased high compared to ozonesondes by similar to 20% at middle to high latitude, although there is a lot of variability in this altitude region. Comparisons between MLS and ground-based lidar measurements from Mauna Loa, Hawaii, from the Table Mountain Facility, California, and from the Observatoire de Haute-Provence, France, give very good agreement, within similar to 5%, for the stratospheric values. The comparisons between MLS and the Table Mountain Facility tropospheric ozone lidar show that MLS data are biased high by similar to 30% at 215 hPa, consistent with that indicated by the ozonesonde data. We obtain better global average agreement between MLS and ozonesonde partial column values down to 215 hPa, although the average MLS values at low to middle latitudes are higher than the ozonesonde values by up to a few percent. MLS v2.2 ozone data agree better than the MLS v1.5 data with ozonesonde and lidar measurements. MLS tropical data show the wave one longitudinal pattern in the upper troposphere, with similarities to the average distribution from ozonesondes. High upper tropospheric ozone values are also observed by MLS in the tropical Pacific from June to November.
