Daily & seasonal gradients of linear fit (SM=bP+a i.e. result=LINFIT(SM,P) Model mean gradients, precip v soil moisture*, CMIP5 models, historical run

(1/1/1990-31/12/2005)

* Known as soil moisture, volumetric soil water layer 1, moisture in upper portion of soil column, moisture in upper 0.1m of soil column, depending on model
