Why Averages Lie About Rain — an interactive explainer

Interactive walk-through of the exact intensity–area decomposition of precipitation volume,

$$V = \Delta t \, T \, \bar I \, \bar A \, K{IA}, \qquad K{IA} = 1 + \rho\,CVI\,CVA,$$

and the factor-wise log-ratio diagnosis of satellite-vs-radar differences, $DX=\ln(X^{(P)}/X^{(R)})$ with $DV = DI + DA + D_K$.
