Posterior CO emissions

The dataset provides CO emissions from anthropogenic sources resulting from a global inversion of multispectral CO retrieval profiles (V9J) from the Measurements of Pollution in the Troposphere (MOPITT) presented in Gaubert et al., (2024). The analysis is performed using a quantile-conserving ensemble filter framework (QCEFF), specifically with a bounded normal rank histogram (BNRH) distribution for the prior, using the Data Assimilation Research Testbed (DART). The posterior emissions are derived on the global Community Atmosphere Model with Chemistry (CAM-Chem) model grid at the horizontal resolution is 0.9° latitude by 1.25° longitude. The prior emissions are CAMS-GLOB-ANT version 5.3 (Soulié et al., 2024) and the Fire Inventory from NCAR version 2.5 (Wiedinmyer et al., 2023).
