This outcome is caused by the smoothing effects of <br />integration in time. Generally, the correlation values for months <br />exceeded the daily results by at least 0.2. <br /> <br />Correlation values from modeling Arizona conditions show somewhat <br />better results than corresponding Gunnison values. Correlation of gauge <br />means (nonmissing mean for 11 Mogollon Rim gauges) with daily and <br />monthly model estimates were 0.76 and 0.92, respectively, exceeding the <br />corresponding Gunnison values by about 0.1. The higher correlation <br />values are probably due, in part, to effects of a less complex <br />mountainous terrain. <br />
