BIOME (Prentice et al., 1992) is a physiologically based model used to predict global patterns in vegetation physiognomy. The input variables are:
Tmin: mean temperature of the the coldest month;
Tmax: mean temperature of the warmest month;
GDD5: growing degree-days on a 5°C base;
GDD0: growing degree-days on a 0°C base;
PTC: Priestley-Taylor coefficient of annual moisture availability.
NOTE: I have been unable to find a good description of how to calculate PTC. This has delayed my inclusion of BIOME into ClimVegWin. However, I think I am on safe ground by estimating it from the ratio of actual evapotranspiration (AE) to potential evapotranspiration (PE). I obtained AE and PE values from the Thornthwaite procedure.
