Soil Temperature and Frost Depth Maps
Knowing the temperature of the soil is important for many activities including agriculture, horticulture, construction, and even grave digging. It is also important for hydrologists because in many situations a frozen soil limits infiltration of water thereby generating more runoff from rain and snowmelt than soil that is not frozen.
Coming soon - Improved maps that will display soil temperature at various depths and reports of ground frost depth from NWS and agency partner networks.
