Impact of spaceborne carbon monoxide observations from the S-5P platform on tropospheric composition analyses and forecasts
We use the technique of Observing System Simulation Experiments (OSSEs) to quantify the impact of spaceborne carbon monoxide (CO) total column observations from the Sentinel-5 Precursor (S-5P) platform on tropospheric analyses and forecasts. We focus on Europe for the period of northern summer 2003,...

| description | We use the technique of Observing System Simulation Experiments (OSSEs) to
quantify the impact of spaceborne carbon monoxide (CO) total column
observations from the Sentinel-5 Precursor (S-5P) platform on tropospheric
analyses and forecasts. We focus on Europe for the period of northern summer
2003, when there was a severe heat wave episode associated with extremely
hot and dry weather conditions. We describe different elements of the OSSE:
(i) the nature run (NR), i.e., the <q>truth</q>; (ii) the CO synthetic
observations; (iii) the assimilation run (AR), where we assimilate the
observations of interest; (iv) the control run (CR), in this study a free
model run without assimilation; and (v) efforts to establish the fidelity of
the OSSE results. Comparison of the results from AR and the CR, against the
NR, shows that CO total column observations from S-5P provide a significant
benefit (at the 99 % confidence level) at the surface, with the largest
benefit occurring over land in regions far away from emission sources.
Furthermore, the S-5P CO total column observations are able to capture
phenomena such as the forest fires that occurred in Portugal during northern
summer 2003. These results provide evidence of the benefit of S-5P
observations for monitoring processes contributing to atmospheric pollution. |
