1. It also can be used on the ice surface, swampland and where after debris flow happens.

2. Other experiments have demonstrated that, at the extremely cold temperatures of a noctilucent cloud, sodium vapour can rapidly be deposited onto an ice surface.

3. Regulation of the Earth’s Albedo is also central to other important climate feedbacks, including the snow/ice surface Albedo feedback as well as cloud feedbacks

4. 27 Hockey is normally played with 5 players (and a goaltender) aside, but due to the much smaller size of The Polar Bear ice surface, only 3 players per team will be allowed on the ice.
