Fig. 6: Daily average modeled vertical profiles and comparison of modeled and observed ALH.

From: Constraints on the modeled vertical distribution of smoke during the 2020 western US wildfires from satellite data

Fig. 6

Daily average RAP-Chem CO vertical profiles in units of ppm averaged over regional domains. The circles in the lowest level depict the daily average CO concentrations retrieved from observational surface stations. The daily average RAP-Chem ALH and TROPOMI AOCH are overlayed on top of the vertical profiles. The scaled RAP-Chem line is the ALH calculated after scaling the RAP-Chem surface CO concentration to the observational surface CO concentrations. All data is masked by smoke defined as above a CO total column threshold of 3e18 molecules/cm2 and colocated to the location of the surface CO stations (a-f). The lower row is also masked by TROPOMI AOCH to account for the gaps in data (d-f).
