Atmospheric carbon dioxide (CO2) retrievals including both thermal and near infrared radiances have been assessed with respect to developing vertical profile CO2 data products from joint retrievals of satellite observations (TES, AIRS, GOSAT). This unique data set will significantly improve the estimation of atmospheric carbon sources and sinks by providing observational constraints on vertical as well as horizontal and temporal distributions of atmospheric CO2 in data assimilation and data fusion approaches. Additionally, we have quantified the theoretical CO2 information content of select spectral channels in the near infrared and thermal infrared towards achieving improved CO2 retrievals. We will leverage these analyses to identify deficiencies in current atmospheric transport modeling schemes and improve carbon flux estimates. Our investigation will also provide a framework with which to evaluate the potential impact of higher resolution vertical profile data that will become available in the post-2010 timeframe from active CO2 remote sensing systems such as the ASCENDS mission recommended by the NRC Decadal Survey.
