Column density of gas-phase methanol (CH₃OH) at a radius of 100 au for the canonical elemental abundances (C/O = 0.43; O/H = 3.2 × 10⁻⁴), and two models where oxygen is globally depleted by factors of 10 and 100 and C/O is set to 2. Shown are the results for the models with grain-surface chemistry, reactive desorption, and fractal grains, and with (GR+RD+FR+D2G) and without (GR+RD+FR) ice-to-gas mass scaling.
