Maps of Point-by-Point Medians of
6-Hour Ensemble Precipitation Forecasts


To get the median at a point on the Earth, sort the ensemble forecast values for that point from least to greatest. The median is the middle sorted value if the number of forecasts is odd. The median is the average of the two middle sorted values if the number of forecasts is even. Presently, there are 15 forecasts in the ensemble, so the median is the eighth value in the sorted list for any given latitude and longitude.
