Document Summary
This is a tutorial session in which i intend that we (together) will address the following questions. A pdf with some supporting images and data will be circulated afterwards. Living in canada there is a lot of winter. But now its seen that there is a lot of nutrient and carbon cycling going on here. The more snow there is the more insulation there is. This has to do with how much air is trapped in there. So as it becomes more packed the worse it is at insulating. Base of snow pack can hold quite a lot of water vapour, warm, and through sublimation the water can go from ice vapour. Therefore the air filled spaces can be saturated with water vapour. As you go up the pack of snow the ability to hold water vapour is less. This creates a gradient and net movement of water vapour towards the top of the snow pack.
