Dear Dr. Wang,

Many thanks for the new draft of the paper. Below are a couple of comments
from me. I also asked Reviewer 3 (Duncan Agnew) to look over it again, and
his additional comments follow below. I think when these things are attended
to in a V3 then all should be fine.

Best wishes again.

Phil Woodworth

p12, 23 - I still think this would read better as:

Since the NAO99Jb ocean tide has an error of only 0.2-0.5 ...

p14,36 - et al.,

p17 - along with the Data Availability statement and the other things, I think there
should be a paragraph here mentioning the Supplementary Material (see examples
in other papers in this journal).

Also there is no reference in the paper as far as I can see to Tables S1 and S2.
The PREM Green's function is said to be 'in the supplement' on p8,21 but I think
this would better read 'to be in the Supplementary Material S3.' (but see
the comment on S3 by Reviewer 3 below). There is no way
the reader can find these unless they are all mentioned in the paper itself.

Additional comments from R3 (Duncan Agnew):

I remain sceptical of the author's claim that NAO99_jB is "better"--at
least over most of the area it covers. But my comments on this are available
to interested readers, so I will not belabor this point.

I think that in the local maps in Figures 4 and 5 the arrow scale could be
made 50% larger, maybe even twice as large, with some gain in seeing
amplitudes, without too much clutter from overlapping.

On line 2 of page 15 "on inputting" should be "using".

I very much like Table 4: this set of statistics is much more informative
than just the RMS.

I think the community would be better served if the S3 were split into
a pdf describing what is in a separate .txt file that gave the actual numbers
for the Green functions. These numbers can be extracted from the .pdf but
it takes some work.

Short summary

Changes in the Earth's elastic strength at increasing timescales of deformation affect predictions of its response to the shifting weight of the oceans caused by tides. We show that these changes are detectable using GPS and must be accounted for but that 3-D or locally-tuned models of the Earth's behaviour around the East China Sea provide only slightly better predictions than a simpler model which varies only with depth. Use of this model worldwide will improve precise positioning by GPS.
