Several tree-ring width chronologies used in the original publication of this article contained a numeric code for missing values and other numeric information, which were inadvertently read and analyzed by our automated code as actual data. Simulations at 35 out of 317 tree-ring sites in the M08 network of our study were affected. Here, we present revised figures and tables derived from applying the original methods to the 282 chronologies which did not contain missing values. In all cases, the non-data values were at the ends of the chronologies. Figure 1 shows a frequency plot of the number of missing years in each chronology containing non-data values. The sites removed from the original data set were all in the western United States (Fig. 2), a region which the remaining sites in the M08 network still cover well. Several statistics reported in the results section 3.2.3 also need revision. The changes from calibration to validation interval in the percentage of the network simulated The online version of the original article can be found under doi:10.1007/s00382-010-0945-5.
