[1]本文首次报道了利用对流层污染测量（MOPITT）卫星观测到的2.3 μm CO泛音波段近红外辐射反演对流层CO的结果。对于陆地上的白天立交桥，这种观测补充了MOPITT在4.7 μm CO基本波段的热红外（TIR）观测，特别是用于限制CO总柱。检索中进行的最佳估计框架，其中有效的辐射误差，由于地球物理源的经验估计。通过与基于标准TIR的MOPITT CO产品和CO轮廓测量的比较，对新的基于NIR的检索进行评价。
[1] We report the first retrieval results of tropospheric carbon monoxide (CO) exclusively using near-infrared (NIR) radiances in the 2.3 μm CO overtone band observed by the Measurements of Pollution in the Troposphere (MOPITT) satellite instrument. For daytime overpasses over land, such observations complement MOPITT's thermal infrared (TIR) observations in the 4.7 μm CO fundamental band, especially for constraining the CO total column. Retrievals are performed in an optimal estimation framework in which effective radiance errors due to geophysical sources are estimated empirically. The new NIR-based retrievals are evaluated through comparisons with both the standard TIR-based MOPITT CO product and CO profile measurements.
