This picture from Houweling et al. (2014) shows the differences between simulated and observed CH4 over the Pacific for the HIPPO mea- surement campaign. The panel at the top left shows the results for a source inversion in which only NOAA surface observations were used. The other panels show results for emissions that are obtained with the additional use of SCIAMACHY satellite data, all with different appraoches for bias correction.
