Indicator: Water Holding Capacity

Status	Automated on Landler
Description	Maximum amount of water that soil can retain, measured in m³/Plot and m³/ha, with an estimate of uncertainty provided as the average standard deviation of WHC estimates.
Unit	m³ (total and per hectare)
Temporal Resolution	Annual Assessment
Spatial Resolution	100m
Data	Satellite data (SMAP, SMOS, Landsat, MODIS, Sentinel 2); ISRIC SoilGrids v2.
Method	Water holding capacity (also known as field capacity) is estimated based on the statistical distribution of soil moisture over time using an empirical percentile approach. Estimates are on an annual basis, but build on a temporal window of three years each. In addition, the method is constrained by soil texture information from SoilGrids.
