AB: Since the first light of the Atmospheric Infrared Sounder (AIRS) onboard NASA's EOS Aqua satellite in the summer of 2002, a new method for retrieving atmospheric constituents, one which can be done in the presence of clouds, has been in use by the AIRS science team. This physical retrieval technique combines linear least squares with singular value decomposition to minimize the dependence of the final solution on the first-guess inputs and their associated errors. Combining AIRS wide swath width with its cloud clearing capability results in more comprehensive daily global coverage than previously possible. By implementing this retrieval method on the 4.67 μm (2180~cm^-1) spectral region we retrieve tropospheric carbon monoxide. Using various aircraft in situ carbon monoxide profiles we begin the task of validating and improving the AIRS CO algorithm.
