Soil and vegetation temperature
The temperature of the soil and vegetation will be measured during the collection of hand-held soil moisture sensor readings. For each field, four sampling locations will be selected to measure soil temperature at two depths –5 cm and 10 cm– using a digital thermometer.
At these same sampling locations, soil and vegetation surface temperatures will be recorded using a thermal infrared thermometer for sunlit vegetation and sunlit soil, as well as for shaded vegetation and shaded soil.
| Sampling location | Depth | Instrument | Measurement technique | |
|---|---|---|---|---|
| Soil temperature | 4 sites:1, 8, 9, 16 | 5 and 10 cm | Digital pocket thermometer | Insert to 5 cm, take reading, then push to 10 cm, take reading. |
| Soil and vegetation temperature | 4 sites:1, 8, 9 16 | Surface | Thermal infrared thermometer | Measure sunlit and shaded soils, sunlit and shaded vegetation. |
