Wavelength (from 0.2-1.8 microns) on the x-axis, contrast ratio on the y-axis). The model is shown by red circles and the retrieval result is overlain. Each molecule of interest is labeled in a separate color to show the individual molecular contributions. CH4 is in orange and shows clear features, CO is in red and the features are not strong and the main absorption feature at 1.55 microns is located within a stronger CO2 feature.
