Validation Summary
The Sentinel-5p TROPOMI L2 CO data product (total CO column) is in good overall agreement with correlative ground-based measurements from NDACC and TCCON. Bias and dispersion estimates (see Table below) meet mission requirements.
| Product ID | Stream | Product | Bias | Dispersion | Special features |
| L2_CO | NRTI | CO column | 6.5% | 5% | Along orbit stripes. Destriped CO data in OFFL from July 2021 onwards 5% SZA dependence of bias. Outliers in SAA and other sporadic locations not filtered by qa_value. Since July 2019 NRTI behaves similar as OFFL. Since the processor update in July 2021 (black vertical line) the bias is reduced to 3%. |
| RPRO/OFFL | CO column | 6.5% | 5% |
The averaged correlation coefficient reaches 0.9 for the TCCON network and 0.85 for the comparison against NDACC sites
Plots show the weekly mean relative differences for the S5P RPRO/OFFL CO columns against NDACC (top) and TCCON (bottom) sites. Sites are sorted by decreasing latitude.
