Table 1 The weighted root-mean-square error (σ) and weighted model bias (μ), where the weight is given by the inverse of the standard deviation of the climatological zonal drifts, for each model during different season and solar flux conditions

From: On a simple, data-aided analytic description of the morphology of equatorial F-region zonal plasma drifts
