The ALERT2000 field campaign was focused on study of the interactions of air chemistry with snow chemistry. We studied optical properties of snow and photochemical reactions in the snowpack. Much of this research has been published.
A photo of the polar sunrise taken from Alert, Inuvik, Canada. At locations north of the arctic circle, the sun drops below the horizon for weeks to months during winter (called the polar night). In springtime, the sun rises and then days get dramaticly longer.
