Note: The S5P L2_CO data product has recently been reprocessed with processor version 02.04.00, replacing older data versions. First validation results for this full-mission reprocessing are published in the quarterly validation report #18. Users still making use of previous data versions are requested to refer to the quarterly validation report #17.
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.
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.
For more information please consult the latest issue of the Sentinel-5p Routine Operations Consolidated Validation Report (ROCVR).
