These maps show the variation of EI30 index that was computed as the product of total kinetic rainfall energy (EC) and maximum 30-min precipitation intensity (I30) in Mato Grosso State, Brazil. During the first and second EI30 periods (October-November and December-March, respectively) many agricultural activities occur in the State. The most critical period is October to February when activities such as tilling, sowing, and harvesting are concentrated. The third period (April-September) is the least critical because the majority of the soils are covered by the crop canopy.
