Soil Temperature

Sector Agriculture, Green infrastructure
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).
End User Urban planners, landscape architects, agricultural sector, gardeners
Calculation method ID Title Period Statistical processing Unit Threshold Comment
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).

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).
