Optimal Rain Gauge Network Design Aided by Multi-Source Satellite Precipitation Observation
Round 1
Reviewer 1 Report
The design and optimization of the rain gauging network plays an important role in the simulation of hydrological processes and the water resources related study. The sparse rain gauging station will seriously affect the simulation accuracy of the hydrological process, and many studies have shown that too dense rain gauging stations have limited improvement in the accuracy of hydrological simulation, and it is necessary to build a reasonable rain gauging network. Considering the deviation characteristics of satellite precipitation observation and ground rainfall monitoring, authors evaluate the spatial heterogeneity of the two-precipitation data, to realize the design optimization of ground rain gauging station network based on satellite precipitation observation. It's an interesting study. The thesis has fluent language, well-organized/reasonable organization, and detailed case analysis. Some minor suggestions on revision are as follows:
(1) For the analysis of Figures 8 and 9 in Section 5.1, it is recommended to supplement the table to count the area covered by each station (Tyson polygon), which will be more intuitive.
(2) In Figures 10 and 12, PERSIANN-CCS seems to perform better than the other two satellites, is this because of the higher resolution of PERSIANN-CCS?
(3) References need to be formatted in accordance with the requirements of the journal, such as the abbreviation of the journal title, etc.

Reviewer 2 Report
Dear authors,
your submission titled "Optimal Rain Gauge Network Design Aided by Multi-source Satellite
Precipitation Observation" is an excellent contribution to the design of effective methods for the implementation of rain gauge networks, able to correctly interpreting the orographic forcing of precipitations. It is well structured and written, and reports a rich bibliography.
For the above mentioned reasons, my opinion is that it is worth of publication as it is
