[1]2003年1月至3月期间，高级地球观测卫星（ADEOS）-II上的改进型临边大气分光仪（ILAS）-II间歇性地观测了北方和南方半球高纬度地区平流层可见光/近红外/红外光谱中的浮质，4月至10月期间连续观测。本研究评估ILAS-II版本1.4（V1.4）气溶胶消光系数在780 nm的数据质量。在北方半球（NH），在20 km以下高度，ILAS-II的气溶胶消光系数（AEC）与SAGE II和SAGE III的消光系数在±10%以内一致，与POAM III的消光系数在±15%以内一致。从20至26公里，ILAS-II AEC小于其他三个传感器的偏差;在北半球，ILAS-II和SAGE II之间的差异从20公里处的10%到26公里处的34%不等。在南半球（SH），ILAS-II AEC在2月20至25公里处比SAGE II灭绝低12-66%。这种差异随着海拔高度的增加而增加。ILAS-II和POAM III之间的比较，从1月至5月在SH（“非PSC季节”）产生了定性相似的结果。从6月到10月（“PSC季节”），ILAS-II灭绝也小于POAM III灭绝17公里以上;然而，ILAS-II灭绝同意POAM III灭绝±15%，从12至17公里在PSC季节。比较结果表明，在两个半球，ILAS-II V1.4 AEC与其他测量结果的偏差在20公里以下相当，而在20公里以上系统性较低，尽管在非PSC季节，平均差异小至102 × 10−5 km−1。
[1] The Improved Limb Atmospheric Spectrometer (ILAS)-II on board the Advanced Earth Observing Satellite (ADEOS)-II observed stratospheric aerosol in visible/near-infrared/infrared spectra over high latitudes in the Northern and Southern hemispheres, intermittently from January to March and continuously from April through October 2003. This study assesses the data quality of ILAS-II version 1.4 (V1.4) aerosol extinction coefficient at 780 nm. In the Northern Hemisphere (NH), aerosol extinction coefficient (AEC) from ILAS-II agreed with extinctions from SAGE II and SAGE III within ±10% and with extinction from POAM III within ±15% at heights below 20 km. From 20 to 26 km, ILAS-II AEC was smaller than extinctions from the other three sensors; differences between ILAS-II and SAGE II ranged from 10% at 20 km to 34% at 26 km in the NH. Over the Southern Hemisphere (SH), ILAS-II AEC from 20 to 25 km in February was 12–66% below SAGE II extinction. The difference increased with increasing altitude. Comparisons between ILAS-II and POAM III from January to May in the SH (“non-PSC season”) yielded qualitatively similar results. From June to October (“PSC season”), ILAS-II extinction was also smaller than POAM III extinction above 17 km; however, ILAS-II extinction agreed with POAM III extinction to within ±15% from 12 to 17 km during the PSC season. The comparisons indicate that in both hemispheres the ILAS-II V1.4 AEC is comparable to extinctions from other measurements below approximately 20 km and systematically low above approximately 20 km although the mean difference is as small as ∼2 × 10−5 km−1 during the non-PSC season.
