Depth frost penetration

Data from 21, dates were analyzed, and frost penetration depths were estimated. There were between 2 and 11 years of data analyzed for the different LTPP.
Frost line - Wikipedia
The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth.
Description:The line varies by latitude, it is deeper closer to the poles. Building codes[ edit ] Building codes sometimes take frost depth into account because of frost heaving which can damage buildings by moving their foundations. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. Not to be confused with the geographical feature Snow line. Finally, in tropical regions, frost line may refer to the vertical geographic elevation below which frost does not occur. There are many ways to predict frost depth including factors which relate air temperature, soil temperature and soil properties. Due to additional cost, this method is typically only used where deeper trenching is not an option due to utility conflicts, shallow bedrock, or other conditions that make deeper excavation infeasible.
