Figure 3 RMSEs #cod#x000b0;C between raw time series or lines and the fitted lines of global averaged SAT anomalies during the periods of a 1901-2005, b 1901-70, and c 1971-2005. The x -axes are labeled with the 27 model numbers; the MME is shown in the 28th column; and the observed trends from GISTEMP and HadCRUT4 are shown in the 29th and 30th columns, respectively. Black bars: lines fitted by LSLF minus Raw; gray bars: lines fitted by the EEMD trend minus Raw; white bars: lines fitted by EEMD MDV and trend components minus Raw.
