Dear authors

I appreciate the effort you put in revising the manuscript.
Yet, some more work has to be done before I can accept the manuscript.
My line numbers refer to the highlighted manuscript version attached to the author response.
Especially, point 1 is a bit cumbersome.

1. The most irritating issue is still the use of the units. Units appear together with a value, not with a variable name. Follow this guideline to not end up with poor formalism!
The following items are examples, please check the whole document.

a) you often add units in brackets like in p.9, l.5-6, p.11, l.10. Readers cannot know if a variable name or units are provided in the brackets. So please write e.g. "(in units of length^{-1})" in p.11, l.10. However, in most cases it is anyway not necessary to provide the units at these locations.
For example p.9, l.5-6: It does not matter, whether length and breadth are given in km, m or some other measure of length.
So please remove units there and on further occasions (p.12, l.4; p.14, l.26; p.14, l.8; p.15, l.8; p.16, l.31; p.12 , l.14 and so on).
p.14, l.9: remove m^{-1} and add it to 17.1 and 8.4 (units appear together with a value, not with a variable name)

b) Keep in mind that it is possible to calculate with units. Just be consistent in your formulations. If you sum up several terms, their units must be convertible into the same units.
Eq.1 p.9, l.17 is still not consistent and a correct formulation is:
fetch = 39.9 km + 0.00781* area * km^{-1}
OR (just to show you that units can be converted!)
fetch = 39900 m + 0.00781* area * km^{-1}
fetch = 39.9 km + 0.00000781* area * m^{-1}

c) units are missing:

p.19, l.23-24: add °C after each term.
p.24, l.10: add K^2 to 0.65 and 0.12
p.33, l.21

for clarity, expression like "mean value +- sigma" could have units after mean value and sigma
abstract: 3.07°C +- 2.25°C
p.19, l.23-24; p.26, l.12

2. check for "it's" = "its"

3. p.23. l.5: comparability = agreement?

4. Even though LWST is defined in the abstrct, define it again at p.2.,l.3

5. p.5,l4: isn't "for" missing now in front of "Lake"?

6. Is equation (8) defined as a ratio? Then r2 should be vertically adjusted.

7. p.26, l.12: a day cannot be delayed by days. It's the warming that is delayed.

8. p. 21, l. 29: lake is not physical quantity, so what does 340g L^{-1} refer to?

Kind regards,
Simon
