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 the mission requirements.
| Product ID | Stream | Product | Bias | Dispersion | Special features |
| L2_CO | NRTI | CO column | +2% | 8% | Along orbit stripes. Destriped CO data available in collection 3. 4% SZA dependence of bias and ±2% seasonal depedence in bias. |
| RPRO/OFFL | CO column | +2% | 8% |
The averaged correlation coefficient reaches 0.9 for the TCCON network and 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.
