no, originally, all fluxes are half-hourly. Delete "original".

In addition: please always give time period (years) you show.

as in any other non-tropical cropland. For the discussion on the 4 permil initiative and all the financial C assets, a map of Europe would be very helpful as well!

many of the comments above by all, to text and figs/tabs, also apply here in the supp

sink/source vs uptake/loss. It is tricky, but we MUST try.

well, many agricultural site PIs do not account for fertilization or harvests either. So we have large uncertainties on the sinks in all ecosystem/land cover types.

compared to ?

no, rephrase

vapor. Which years?

which years?

vapor, throughout the mss. We never measure water fluxes!

I would give this comparison at least in the suppl

no, correlation is r, not r2. Since all your values are positive, you give regression results.

up to now, you gave correlation coefficients, now you start to give regression coefficients. Why?

2020 or 2021?

you "only" model fluxes, not sinks correct? I am asking because above the tropical "sink" was mentioned. At the beginning of the results, you use the term "sink" as well. But: negative NEE/positive NEP shows net CO2 uptake, not necessarily a (long-term) sink, for this you would need all im/exports, even for forests. NEE clearly does NOT equal a sink in agricultural or regularly managed sites. We need to be clearer in our terminology.

should be "Among", "between" is only a comparison of 2

I only notice it here: i.e. and e.g. need both commas after the their last dot, probably missing throughout the mss

turn around the title of the color code by 180 degrees. All axis/legend titles should "look" into the same direction. Good scientific convention to avoid headaches ;-)

Results in past tense as well ;-)

above you say 2021. What is correct?

check your verb tenses, you switch back and forth. MatMet always in past tense ;-)

NDVI? really W?

for me, they come too late, after the first result (Fig. 1)

keep you verb tense, past tense in the sentence before, no present tense. It is confusing (see above, what is new, what is old)

for what does this abbreviation stand? Would be good to know.

T or ET?

it is actually water vapor, not water
