Definition
Average layer soil temperature is the depth-averaged temperature beneath the soil surface at a specified layer. These soil temperatures may contribute to the low frequency variability of energy and water fluxes. They are important measured quantities in analyzing of the ground heat flux, and then the energy and water cycles.
In the Land Data Assimilation Systems (LDAS), the number of vertical levels for soil temperature is model specific. Please follow the table below for the correct depths of soil layers.
| Model | Vertical Layers |
CLM (10 layers) | 0-0.018, 0.018-0.045, 0.045-0.091, 0.091-0.166, 0.166-0.289, 0.289-0.493, 0.493-0.829, 0.829-1.383, 1.383-2.296, and 2.296-3.433 m. |
| Mosaic (3 layers) | 0-0.02,0.02-1.50, and 1.5-3.50 m. |
| Noah (4 layers) | 0-0.1, 0.1-0.4, 0.4-1.0, and 1.0-2.0 m. |
| VIC (3 layers) | 0-0.1, 0.1-1.6, and 1.6-1.9 m. |
