Assessment of Changes in Annual Maximum Precipitations in the Iberian Peninsula under Climate Change
Round 1
Reviewer 1 Report
The authors have developed a good work but I have doubts about the procedure of interpolation of spatial precipitation. The authors explain in line 194 that they have use linear interpolation in 5km grid, so there is no regionalization nor any consideration of orographical effects. Indeed, the quality of the figures can be improved. For example, in Figure 1, all the information seems very confusing by the point clouds or the border effects in Figures 2 and 3 are neglected
Author Response
The Authors would like to express their gratitude to the Reviewer because of the comments. Some revisions were made and the clarity of some parts of the text has been improved.
Regarding the first Figures cited by the reviewer, despite the amount of points in the image, the purpose of the Figures was a general comparison without going into details. That is because the main objective of the article is not the comparison between models and observations, but future projections. Therefore, the authors consider that no further detail is needed in these Figures, as long as it is seen that the average errors are not high. In addition, another problem added in these figures is that if the points are too small to avoid overcrowding in areas with many stations, in other areas with less density the result of the analysis is not clearly seen.
On the other hand, regarding the posible regionalization of the rest of the Figures shown, The Authors understand that no regionalization nor more complex interpolation due to the orography is needed. That is because Regional Climate Models used in this study already consider the orography of the territory, with a spatial resolution of nearly 12 km. Therefore, the orographic effects have already been considered in the results, and the interpolation carried out at work has been with a single aesthetic purpose. However, a sentence was included in line 199, in order to clarify that. The sentence is the following:
“Such a simple interpolation procedure was selected as RCMs have already considered orography, and the use of more complex techniques would not have changed the result obtained substantially.”
Besides the comments made by the reviewer, the Figures 8.a, 8.c, 9.a, 9.b, 9.c were corrected, because of an error in the colourbar.

Reviewer 2 Report
The paper "Assessment of changes in annual maximum precipitations in the Iberian Peninsula under climate change" by Carlos Garijo and Luis Mediero applied 12 combinations of RCMs outputs from the EURO-CORDEX project to assess the future changes of precipitation quantiles in a regionalised area, the Iberian Peninsula and the Balearic Islands. This study is very interesting and meaningful for constructing the hydraulic facilities. The results, uncertainty analysis and discussion are pretty good. I recommend publication after a minor revision. 1. line 6-9 The two authors' affiliation are the same, one is enough. 2. I propose to add an overview map of the study area, on which the river basins in table 3 and 4 are marked. 3. line 451 A space is missing before the left parenthesis.Author Response
The Authors would like to express their gratitude to the Reviewer for pointing out these mistakes. Some changes were made in the manuscript.
The affiliation of the second autor was removed, as indicate the rules of the journal. A Figure (Figure 5 in the new versión) of an overview map of the study area was included. Besides, a explanatory sentence in line 333 was written:“The geographical distribution of the regions can be seen in Figure 5, with different colours assigned for each region.”
The space in line 451 was included.Besides the comments made by the reviewer, the Figures 8.a, 8.c, 9.a, 9.b, 9.c were corrected, because of an error in the colourbar.
