Dear authors,
You have done a good work in responding the referee comments.I have only a few technical comments for the manuscript that should be addressed before it can be accepted for final publication to GMD:
- The equations, figures and tables in supplements should be numbered as (S1), Fig. S5 or Table S6 etc. Sections on the other hand should be numbered as S3, S3.1, and S3.1.1.
- And furthermore the figures/tables should be refered from the main manuscript based on the figure and table numbers. For example on P6, L6 where (Supplement) should be (Fig. S1, Table S1) but also elsewhere in the manuscript
- Table 1-3: Horizontal lines should appear above and below the table. Now in Table 3 there is only the below line. Later tables are OK.
-Figure 8: Elsewhere local time is used instead of LT. Please, systematize.
-P28, L28: references extend over the side
-References with websites (urls) should be avoided as they might change in the future. In Code and Data Availability section both https://www.clm-community.eu/ should be removed. It is also tricky to use Dominik Brunner's email as emails are not permanent so rather say upon request etc or leave simply "The code of COSMO-BEP-Tree is made freely available to any user with a valid CLM-Community membership". Also the references to MODTRAN should be changed to those suggested in their website:
--------
What reference(s) should be used for MODTRAN?

Recent MODTRAN publications include [Berk et al., 2014; 2015]. The 2014 paper should be used as a general MODTRAN reference, while the 2015 paper focuses on the MODTRAN line-by-line algorithm:

Short summary

Street trees are regarded as a powerful measure to reduce excessive heat in cities. To enable city-wide studies of the cooling effect of street trees, we developed a coupled urban climate model with explicit representation of street trees (COSMO-BEP-Tree). The model compares well with surface, flux and satellite observations and responds realistically to changes in tree characteristics. Street trees largely impact energy fluxes and wind speed, while air temperatures are only slightly reduced.
