Entropy outliers. (A) Fraction of cells that display an entropy outlier value, measured in terms of a modified median z-score, over the period of observation. (B) Distribution of the number of outlying days per cell. (C) Georeferenced outlying activity on the Milano area. Bigger circles represent cells with a larger number of outlying days while the cyan-to-purple color indicates the outlying period from early November to late December.
