[1]用SCISAT上的大气化学实验(ACE)卫星掩星(MAESTRO)仪器反演的平流层和对流层中的气溶胶消光系数与臭氧探空仪、SCISAT、SAGE III和POAM III上的傅里叶变换光谱仪(ACE-FTS)的测量结果进行了统计比较。在中高纬度北部16-30公里范围内，MAESTRO和臭氧探空仪测得的臭氧混合比廓线在5-10%范围内吻合。此外，ACEFTS和MAESTRO臭氧剖面在距离16-50公里的∼范围内符合5-15%。Maestro臭氧图谱显示了系统的偏差，这与日出(SR)和日落(SS)事件相反，也可以在与SAGE III和POAM III臭氧的比较中看到。Maestro SS臭氧剖面在16-40公里范围内与SAGE III或POAM III SR或SS反演结果基本一致，但在40-55公里范围内表现出明显的高偏差，最高可达∼的20-30%。Maestro SR臭氧图谱显示，与SAGE III和POAM III SR或SS测量相比，在20-50公里范围内∼的偏差为5-15%。在15-40千米的SR和22-35千米的SS测量范围内，ACE-FTS和MAESTRO的NO2分布在10-15%的范围内吻合。此外，大师2号剖面与Sage III 2号剖面在25-40公里的10%范围内基本一致。Maestro 2号剖面与POAM III SR剖面在25-42千米范围内符合5-10%。然而，与POAM III SS剖面相比，Maestro No2剖面显示出20-25公里之间的低偏差(∼30-50%)，25-32公里之间的高偏差(10-30%)，以及33公里以上的低偏差，随着海拔的升高而增加到50-60%。
[1] Atmospheric retrievals of ozone and NO 2 by the Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO) instrument which is part of the Atmospheric Chemistry Experiment (ACE) satellite aboard SCISAT are compared statistically with coincident measurements by ozonesondes, the Fourier Transform Spectrometer (ACE-FTS) also aboard SCISAT, the SAGE III and the POAM III instruments. The ozone mixing ratio profiles from MAESTRO and ozonesondes agree within about 5-10% from 16-30 km in the northern middle and high latitudes. Further, ACE-FTS and MAESTRO ozone profiles agree within ∼5-15% from 16-50 km. MAESTRO ozone profiles show a systematic bias which is opposite for sunrise (SR) and sunset (SS) events and was also seen in comparisons with SAGE III and POAM III ozone. MAESTRO SS ozone profiles mostly agree within 5-10% from 16-40 km with either SAGE III or POAM III SR or SS retrievals, but show a significant high bias from 40-55 km, reaching a maximum of ∼20-30%. MAESTRO SR ozone profiles show a low bias of ∼5-15% from 20-50 km, as compared to SAGE III and POAM III SR or SS measurements. The NO 2 profiles agree within about 10-15% between ACE-FTS and MAESTRO from 15-40 km for the SR and 22-35 km for the SS measurements. Further, MAESTRO NO 2 profiles agree with SAGE III NO 2 mostly within 10% from 25-40 km. MAESTRO NO 2 profiles agree with POAM III SR profiles within 5-10% from 25-42 km. However, compared to POAM III SS profiles, MAESTRO NO 2 profiles show a low bias between 20 and 25 km (∼30-50%), a high MAESTRO bias between 25 and 32 km (10-30%), and again a low bias above 33 km that increases with altitude to 50-60%.
