Short summary
Chemicals are commonly found in snowpacks throughout the world and may be degraded by sunlight; some previous research has reported faster decay rates for chemicals on the surface of snow and ice compared to in water. We found photodegradation on snow can be as much as 30 times faster than in solution for the three dimethoxybenzene isomers. Our computational modeling found light absorbance by dimethoxybenzenes increases on the snow surface, but this only partially explains the decay rate.
