The values for the above mentioned performance measures for v and w for unstable
as well as stable conditions are summarised in Tables VI and VII respectively
along with their ideal values. The values of statistical parameters for v indicate
generally satisfactory behaviour. The unstable aswell as stable schemes for v show
no significant overprediction or underprediction since their MG values lie close to
unity. Also relatively low values of geometric variance (VG) here indicate typical
scatter less than the mean. Correlation coefficients of 0.78 and 0.98 for daytime and
night-time respectively as well as very low values of NMSE and Fractional Bias
(slight underprediction) show encouraging performance of the scheme. Similarly,
98% and 100% values within a factor of two for unstable and stable conditions
respectively are also satisfactory. Hence, from the above viewpoints the schemes
adopted for the estimation of v in the present study perform satisfactorily.
In the case of w it has been observed that for stable conditions, the various
performance measures show highly satisfactory behaviour indicating that the
