Spatio-temporal abundance variation of selected COMs on the grain (dot-dashed line) and in gas phases (continuous line) are shown for the hot core model cr16-r3-l2. Black dashed and continuous lines show the radial variation of the density and the temperature respectively. Time-stamps (in year) for different temporal snapshots are annotated in the upper right corner of the respective plots. Note the alternative labeling of the density and temperature axes on the right side of the respective plots.
