摘要

Comparisons of aircraft measurements of carbon monoxide (CO) to the retrievals ofCO using observations from the Measurements of Pollution in The Troposphere(MOPITT) instrument onboard the Terra satellite are presented. Observations madeas part of the NASA INTEX-B and NSF MIRAGE field campaigns during March–May 2006are used to validate the MOPITT CO retrievals, along with routine samples from 2001through 2006 from NOAA and the MOZAIC measurements from commercial aircraft. Asignificant positive bias, around 20% for total column CO, in MOPITT CO was foundin the comparison to in situ measurements during 2006. Comparisons to the long-termrecords of measurements from NOAA and MOZAIC revealed an increasing bias in the V3MOPITT CO retrievals over time. The impact of an instrumental drift is illustrated through retrieval simulations.
