Box plots of statistical metrics based on the results from the analysis of DM8HR data at 185 monitoring sites: (a) Standard deviation, (b) Root mean square error, (c) Mean bias, (d) Coefficient of variation, (e) Normalized mean error, and (f) Normalized mean bias. The lower and upper edges of the boxes represent the 25th and 75th percentile values while the whiskers represent the 5th and 95th percentiles.
