Implementations of realistic crop managements are crucial for current land surface models to better simulate crop growth simulations. This manuscript applied double-cropping and interactive irrigation in Noah-MP that better captured crop growth seasonal variations in the North China Plain. The manuscript is well written and the overall flow is clear. There were several comments need to be addressed before considering for publication.

Comments:

The authors mentioned incorporating crop growth is important for understanding the land-atmosphere interactions, but the manuscript did not show any land surface simulations. I suggest the authors include a result section to show how the energy fluxes and soil moisture changed with double-cropping and irrigation.

Although the recalibration process was described in the supplement, it still unclear whether such calibration of the double cropping scheme only at Yucheng site then applied the calibrated parameters across the whole domain? Or you perform calibration at Yucheng site and at regional scale separately?

The analysis focused on the North China Plain, but all the plots showed much large region of eastern China that seems very distractive for me. I suggest to zoom in the North China Plain for all your plots.

The current flow of section 3.2 is a little bit confusing. Why only show regional crop grain yield in 2005? The validations should focus on 2005-2014.  I suggest to first show the site calibration (2005) and validation (2005-2014). Then show the regional crop calendar and grain yield validation for 2005-2014.

Figure 8. What LAI data used in the validation?

Line 22-24. I don’t think it is necessary to list the next phase of your research in the abstract.

Line 120. The WRF model version is 4.3, but it was 4.5 in your title.

The experiment design did not mention the nesting and the domain range. The figure 1 made me think you have double-nesting domains, where the smaller rectangle is the inner domain.

I suggest to rearrange figure 4. The color bar for irrigation fraction plot is under the targe irrigation plot. Similar problem for figure 6, you want to move the green-blue color bar up so it could underneath the maturity plots.
