Soil temperatures at five depths through the year
Passage type: Data Representation
Heat moves through soil from warmer layers toward cooler layers. At a weather station in a mid-latitude region of the Northern Hemisphere, thermometers were buried in bare soil at 5 depths below the ground surface. On the 15th day of every other month for one year, the average air temperature 1.5 m above the ground and the average soil temperature at each depth were recorded. The results are shown in Table 1.
Table 1
| Month | Air (°C) | Soil at 0.1 m (°C) | Soil at 0.5 m (°C) | Soil at 1.0 m (°C) | Soil at 2.0 m (°C) | Soil at 4.0 m (°C) |
|---|---|---|---|---|---|---|
| January | −4 | −1 | 2 | 5 | 8 | 11 |
| March | 4 | 3 | 3 | 4 | 6 | 10 |
| May | 14 | 13 | 10 | 8 | 7 | 8 |
| July | 22 | 20 | 17 | 14 | 11 | 9 |
| September | 16 | 16 | 16 | 15 | 13 | 10 |
| November | 4 | 5 | 8 | 10 | 11 | 12 |
