A prototype optimal estimation CO retrieval framework using CrIS thermal-IR spectra is being developed and undergoing initial testing and evaluation. The goal is construction of a multi-decadal climate-quality data record, consistent with MOPITT, extending into the post-EOS/Terra era, given the planned JPSS mission schedule. The EOS/MOPITT instrument has an ongoing and unprecedented record of CO retrievals since early 2000. CrIS CO offers the potential to significantly extend the MOPITT thermal-IR retrieval record as well as providing expanded spatial coverage. The prototype CrIS CO optimal estimation retrieval system is outlined and initial results described. CO retrievals have been carried out during the fires near Fort McMurray Canada in May 2016, and in the winter-season California Central Valley. These initial CrIS retrievals are in reasonable accord with independent measurements from MOPITT (Fort McMurray: Hi-Res Spectra) and DISCOVER-AQ (CA Central Valley: Low-Res Spectra). This work provides a robust foundation for planned improvements, as well as a demonstration of the utility of this approach to long-term CO record development.
