Figure 3: measured rainfall <strong>and</strong> potential evapotranspiration (top), <strong>and</strong> soil water storage <strong>and</strong> repellency<br />

(bottom) for the Açores 1 slope; soil water repellency is indicated as the severity class associated with the<br />

result of the Molarity of Ethanol Droplet (MED) test, <strong>and</strong> the shaded area represents the interquartile area<br />

(between the 1 st <strong>and</strong> 3 rd quartiles).<br />
