After publication of our paper entitled “Extreme precipitation and climate gradients in Patagonia revealed by high-resolution regional atmospheric climate modeling” (Lenaerts et al. 2014, hereinafter L14), we discovered three notable errors. Although nothing changes the results, we would like to communicate these errors by means of this corrigendum.
First, Table 1 in the original paper documented that all Chilean Water Directorate (DGA) and Chilean Weather Service (DMC) stations covered the period 1950–2007. However, most of the stations cover a considerably smaller time period. This error will change nothing to the results; we have already selected the overlapping years between the observations and Regional Atmospheric Climate Model version 2.3 (RACMO2) data, as indicated in the text of the original paper. The corrected Table 1 is displayed below.
List of available weather stations used in this study for model evaluation. Shown are the abbreviated and long name, latitude and longitude, station elevation in meters above sea level, available time period, available variables (PR = precipitation; T = temperature; U = wind speed), and the source of the data. DGA is the Chilean Water Directorate and DMC the Chilean Weather Service. S2003 refers to Schneider et al. (2003).
Second, in Table 2 of L14, the exact measured accumulation at Cerro Gorra Blanca is not 1.00 but rather 0.97 m w.e. yr−1 (w.e. indicates water equivalent) and covers only the period July 2000–July 2001. This is described in Schwikowski et al. (2006).
Third, we came across an error in the text concerning the significance of the upper-atmospheric temperature trend (p. 4619, under the heading “Recent trends”). In contradiction to the text of the original paper, but in accordance with Fig. 11a therein, the 1979–2012 temperature trends at 700 hPa are nowhere significant in Patagonia. The text should therefore read: … respectively. RACMO2 suggests an important but statistically insignificant temperature decrease, especially in western Patagonia (from −0.005 to −0.01 K yr−1). Trends in precipitation are spatially irregularly distributed and also mostly not significant, although there are some hints …
