The Toolik Lake Grid map focuses on the south side of Toolik Lake. This area is one of the principal intensive research areas at the Toolik Lake Field Station. It includes many experimental research sites where long-term observations and experiments are being conducted, including the greenhouse and snow-fence experiments. The grid was constructed in 1989 to provide geographic referencing for experimental plots and to provide a sampling scheme for periodic measurements of snow, active layer and plant communities.
The amount of water (lakes, ponds, streams, wetlands), strongly affects the reflectance of the land surface over large areas of Alaska. The percent water was based on the number of AVHRR water pixels in each polygon divided by the number of pixels in each polygon.
The classes of water coverage in a polygon were reported as follows: 0%, 1-5%, 5-25%, 25-50%. 50-75%. 75-90%, 90-100%
