Dear Dr. Wen,

Thank you submitting the revised version of this manuscript. I have to admit that it was quite tedious to identify the actual changes in the revised version because your response to the reviews (including the suggested changes and the respective lines numbers) and the actual changes do not correspond well to each other.
Nevertheless, you have addressed issues that were raised with one exception. Rev.2 asked for a statement on model performance in the abstract. You proposed a modified text (“The model was calibrated using field measurements of daily stream discharge, evapotranspiration, and stream DOC concentrations and met the satisfactory standard of the Nash-Sutcliffe efficiency (NSE) > 0.5. The calibrated model was used to estimate and compare the daily DOC production rates (Rp; the sum of local DOC production rates in individual grid cells) and the daily DOC export rates (Re; the product of concentration and discharge at the stream outlet, or load).”): However, the revised version lacks the information on model performance. Please include this into the revised version.
Sincerely

Christian Stamm
