Actual and potential crop evapotranspiration, and calculation of soil water balances.
Ecological assumptions entered into the models that were then used to predict evapotranspiration and net photosynthesis.
For example, deforestation can mean smaller evapotranspiration which leads to reduced rainfall.
The climate variable is based on three levels of potential evapotranspiration (ET ), which are represented by three sites in eastern Colorado.
The UNEP Aridity Index (based on a ratio of annual precipitation to mean annual potential evapotranspiration) data added to the karst dataset.
