 VIEWblue — OBSred — model STATISTICSBias — squared biasSTD — squared difference between standard deviationsCor — lack of correlation weighted by the standard deviations STATISTICS root-squaredBias — biasSTD — difference between standard deviationsCor — root-squared lack of correlation weighted by the standard deviations DIURNAL   SEASONAL   Formulations from Kobayashi K. and Salam M.U. (2000) :

• Squared bias
$$\mathsf{SB} = (\bar x - \bar y)^2$$
• Squared difference between standard deviations
$$\mathsf{SDSD} = \left(\mathsf{SD}_x - \mathsf{SD}_y \right)^2 = \left( \sqrt{\frac{1}{n}\sum\limits_{i=1}^{n}{(x_i-\bar x)^2}} - \sqrt{\frac{1}{n}\sum\limits_{i=1}^{n}{(y_i-\bar y)^2}} \right)^2$$
• Lack of correlation weighted by the standard deviations
$$\mathsf{LCS} = 2 \ \mathsf{SD}_x \ \mathsf{SD}_y (1-r)$$
$$r = \left[ \frac{1}{n}\sum\limits_{i=1}^{n}{(x_i-\bar x)(y_i-\bar y)} \right] / (\mathsf{SD}_x \mathsf{SD}_y)$$
