TATM
Product Information | Description |
|---|---|
| Parameters | TATM profile |
| Data Product Provenance | MUSES Version 1.11 |
| Approximate file size | 130MB |
| Spatial coverage | Regular collections have global coverage: Nominal latitude range: 70 N to 50 S Nominal longitude range: -180 to 180 Special collections: Spatial coverage varies by collection |
| Temporal coverage | Each L2 Standard file contains 1 day of data. |
| File format | Netcdf |
| Vertical sensitivity | Estimates of atmospheric temperature typically have the greatest sensitivity between 825 hPa and 100 hPa, with significant sensitivity in the stratosphere. 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 TATM profiles and degrees of freedom for signal (DOFS). |
| 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 TATM below the clouds. |
| Uncertainty | Profiles levels have approximately 0.5 K observational error (does not include vertical smoothing error). |
| Validation Stage | Stage 2 according to NASA guidelines https://science.nasa.gov/earth-science/earth-science-data/data-maturity-levels |
| Retrieval Levels | 31 levels: from surface to top-of-atmosphere |
| FillValues | -999 |
