Dear Shannon Brown,

Thank you for revising your manuscript entitled 'EVALUATION OF A LOWER-POWERED ANALYZER AND SAMPLING SYSTEM FOR EDDY-COVARIANCE MEASUREMENTS OF NITROUS OXIDE FLUXES' and for thoroughly taking the reviewers' comments into account.

Having a system for N2O field scale flux measurements with better frequency response than previous systems and at the same time lower sample pump power consumption is a step forward with regard to remote agricultural areas where high-quality power supply is not always available. The technical characterization of the system is rigorous and well done. Including the suggestions of Referee #2 regarding spectral losses and flux detection limit has further improved the paper.

The study is a valuable contribution to the eddy flux community and can be published subject to only a few minor additions:

- On page 18, lines 20-24 and in Fig.8 it should again be indicated that no gap filling was used. Otherwise these total emission numbers do not make sense and may mislead the reader when trying to compare these figures with other studies.

- Accurate quantification of N losses from fertilized agricultural land is crucial when trying to optimize fertilizer type, amount, application technique, and yield while at the same time keeping N emissions on a low level. I'm missing a rough estimation of the ratio of N emitted to N added (i.e. emission factor) in order to further assess the field applicability of the system. Is information about amount of fertilizer added (N content) available? For this purpose, a simple gap filling routine should be performed (something like mean diurnal variation). Do the results make sense and are they comparable to other studies (maybe even to chamber measurements at the same site)? If available, these information should be added on page 15, lines 10-25.

- Section 3.4 should be 3.3.

Thank you for submitting your work to AMT.

Best regards,
Christian Brümmer
