Global Annual Freezing and Thawing Indices, Version 1
The total annual freezing and thawing indices are defined as the cumulative number of degree-days when air temperatures are below and above zero degrees Celsius. The total annual freezing index has been widely used to predict permafrost distribution; estimate the maximum thickness of sea, lake, and...
