Figure 1 in “Short-term precipitation and temperature trends along an elevation gradient in Northeastern Puerto Rico” by Van Beusekom et al. (2015) was incorrect in the paper. The sites were incorrectly labeled and are corrected here in Table 1. The authors would like to thank Sheila Murphy (U.S. Geological Survey) for identifying this problem. Additionally, the station elevations reported in the paper were determined using differing methods that lead to slight inconsistencies in the elevations. To correct this, the elevations have been standardized using station x–y coordinates and elevation above mean sea level extracted from the U.S. Geological Survey 10-m DEM. Revised columns are shown in Table 1 here. The comparisons with the outside data source were reanalyzed using these locations and elevations, and the regressions of Sen’s slopes of the trends versus elevation were recomputed using these elevations. The results shown in Figure 10 (no relationship between temperature trends and elevation) remain the same. The results shown in Figure 9 change slightly. The relationship for all months’ precipitation with elevation should be y = (0.75 × 10−4)x + 0.15 with a p value of 0.126 for the slope and 0.001 for the intercept, with y as the change in mean daily precipitation per year (mm) and x as elevation (m). The relationship for driest months’ precipitation with elevation should be y = (2.05 × 10−4)x + 0.10 with a p value of 0.001 for the slope and 0.013 for the intercept, with y as the change in mean daily precipitation per year (mm) and x as elevation (m). These are approximately a 3% reduction from the reported slopes of increasing change of mean daily precipitation with elevation. The individual station trends do not change, just the magnitude of the increase of the trends with elevation.
