Tropospheric CO observed with the NAST-I retrieval methodology, analyses, and first results

摘要: High-resolution infrared spectra from aircraft and space-based observations contain information about tropospheric carbon monoxide (CO) as well other trace species. A methodology for retrieving CO such remotely sensed spectral data has been developed the National Polar-Orbiting Operational Environmental Satellite System’s Airborne Sounder Testbed—Interferometer (NAST-I). profiles of troposphere, together with its thermodynamic properties, are determined by use a three-stage retrieval approach that combines algorithms physically based statistical eigenvector regression, simultaneous iterative matrix inversion, single-variable error-minimization profile inverse retrieval. The NAST-I is collecting while it aboard high-altitude throughout many field campaigns. Detailed analyses on instrument system along results several recent campaigns presented to demonstrate capability.
