Sentences with phrase «optimum averaging method»

Jones et al. (2001) temperature data have been averaged by both a standard weighting method, used in the SAR, as shown by the dashed smoothed curves, and by an optimum averaging method (Shen et al., 1998; Folland et al., 2001) as shown by the bars and solid smoothed curves.

Not exact matches

Table 2.2 shows linear trends of the annual optimum averages, and twice their standard errors, for the globe and hemispheres using the restricted maximum likelihood method as in Table 2.1 and allowing for the annual uncertainties due to data gaps, urbanisation over land, and bias corrections to SST.

Optimum averaging gives less weight to areas of high data uncertainty than do ordinary averaging methods, and it takes much better account of data gaps.
