Empirical Models of Wind Conditions on Upper Klamath Lake, Oregon

Table 3. Goodness-of-fit statistics for the Upper Klamath Lake, Oregon, gap-filling wind models during the calibration (May 12–September 29, 2007) and validation periods (May 12–September 30, 2006).

[NASH and BIAS are the Nash-Sutcliffe error and bias error respectively, between the simulated and observed time series. NASH values are unit-less, BIAS values are in meters per second. Abbreviations: PPM1, preprocessing (filtering) method 1; PPM2, preprocessing (filtering) method 2; NOPPM, unfiltered data; n-s, north-south wind component; e-w, east-west wind component]
