| Description | Soil temperature is the average temperature of urban soils at 10 cm depth. This is important for urban vegetation activity and soil microbial activity which controls soil carbon respiration (Kaye et al. 2005, Crawford et al. 2011). | ||||||

| soiltemp | Soil temperature | mounthly | Average monthly soil temperature | °C | Not available yet | ||
| Provenance | Drought is based on temperature computed by the HARMONIE model. | ||||||
| Validation | The simulations made by HARMONIE-AROME in Urban SIS has been validated against observations in Urban SIS deliverable 5.1, where an overview is given in Table 4. | ||||||
| Calculation caveats |
Soil temperature is dependent on soil thermal properties, moisture, and soil composition (Dudhia 1996). Spatial representation: S1, S4 |
||||||
| Motivation | This is an important variable for plant and agricultural growth and health as well as carbon cycling processes by vegetation and soils (Kaye 2005, Crawford 2011). | ||||||
