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. High pollution underestimated.
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.
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.
