Product Information | Description |
|---|---|
| Parameters | CO profile |
| Data Product Provenance | MUSES Version 1.10 |
| Approximate file size | 15 MB |
| Spatial coverage | Regular collections have global coverage:
|
| Temporal coverage | Each L2 Standard file contains 1 day of data. |
| File format | netcdf |
| Vertical sensitivity | Estimates of carbon monoxide concentrations from thermal infrared satellite observations are most sensitive to CO variability between 850 and 200 mb. However, sensitivity depends on observed scene parameters such as thermal contrast and can be variable. Users should assess individual retrieval sensitivity using the averaging kernel (AK) for CO profiles and degrees of freedom for signal (DFS) or column AK for total column CO. |
| Data quality | The L2 Standard data products have undergone a pre-quality check, which involves checks for retrieval convergence and measurement sensitivity. There are no checks for clouds or land versus ocean as we do not find these to substantively affect the quality of the retrieval as long as the retrieval has converged. Note that retrievals over thick clouds will not be sensitive to CO below the clouds. |
| Uncertainty | Profiles levels have approximately 7% observational error (does not include vertical smoothing error). |
| Validation Stage | Stage 3 according to NASA guidelines https://science.nasa.gov/earth-science/earth-science-data/data-maturity-levels |
| Retrieval Levels | 14 levels: from surface to top-of-atmosphere |
| FillValues | -999 |
