Dear Authors,
I have gone through your corrections and modified manuscript. There are a few technical points that need to be considered before accepting the manuscript to GMD. See list here:

P2, L10: Simulate should be simulated
P2, L18: Models should be model
P2, L25: The reference should be after bias
P5, L3: degree mark missing from W and E
P5, L6: Webpages should not be provided as web links. As there is already the reference I suggest to remove the whole link. There is extra bracket after the reference
P6, L26: comma missing after the equation
P7, L11: have should be has
Figure 1: Units (degree) are missing from x- and y-axes
Figure 2: The figure needs to be made more clear. There is a) on the right hand side figure but no label on the left subplot. The different parts of the figure in not appropriate explained in the figure explanation. TG and BDOTM not opened in figure explanation. The units of TG missing from right-side figure. Also x-axis legend is missing.
Figure 4: TG not explained and degree missing from the figure. a-d missing from the figure and figure caption.
Figure 5: y-axis explanation with units should be added to the figure. Degree missing in from of C on y-axis. TG not explained in the figure explanation. JJA not opened.
Figure 6: “panel” can be removed from panel a, panel b,…TG not explained and its units are missing.
Figure 7-8, A2, A4, A6 : SLP needs to be opened in figure explanation, x and y-axis variables and units are missing
Figure A1, A3, A5,: TG not explained and degree missing from the figure. Box plots not explained.

In the code and data availability section, instead of just marking the websites, the correct bibliography entry should be retrieved from the Zenodo entry itself and be included in the bibliography. This should be cited from the section.

Short summary

This paper presents an adaptation of a method of "importance sampling" to simulate large ensembles of extreme heat waves (i.e., the most extreme heat waves that could be), given a fixed returned period. We illustrate how this algorithm works for European heat waves and investigate the atmospheric features of such ensembles of events. We argue that such an algorithm can be used to simulate other types of events, including cold spells or prolonged episodes of precipitation.
