The submitted manuscript discusses a novel application of ensemble model output statistics. It is well written, well structured, and the conclusions drawn by the authors are well supported by the results. In particular, the
comparison between local and massif scale model estimation is of interest for a broader audience, as it allows to quantify the potential for post-processing at unobserved sites. Accordingly, I highly agree with the
positive reviews of both referees and therefore recommend publication pending to a couple of minor revisions as indicated by referee #1 and stated below.


I've spotted a few typos (probably this list is not exhaustive):

p3/l11: refered --> referred
p5/l4: what is ISBA?
p5/l31: are built
p7/l27: represents -> represent
p20,l22: a space is missing: 10cm[, [10cm
p25, l34: true than -> true that
Figure 1: the color scale for altitude range 2400-3000 and 4200-4800 cannot be distinguished. Probably not relevant, but still not nice.

The manuscript is ready for publication subject to a very minor technical correction.

Being a bit picky: I think Referee 1 pointed at both occurrences of the word "significant" on page 25 / line 13. In line with Referee 1 I recommend to replace the phrase "was significant" by something like "was considerable", as you haven't performed any statistical test for this.
