Altitude above the midplane as a function of the abundance relative to H of CH3OH at 100 au. The blue line shows the abundance produced by model M-HUV-LH; the red line shows the abundance produced by model M-HUV-B14. The abundance dramatically drops at ~ 2 scale heights in both models, although M-HUV-B14 maintains a larger abundance than M-HUV-LH at high altitudes.
