CO retrievals based on MOPITT near-infrared observations

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.
