Update the synbath grid (to version 2) in the main server

[Esteban82]

I will update the synbath grids (to version 2) in the main server.

The steps to follow are:

• Test the files (already in the test server).
• The info in gmt_data_server.txt is already updated.
• Copy and place the updated earth_synbath data from the test server to the main server.
• in the remote-datasets repository, update the information for of the grid and in the changelog.
• Close this issue.

I just update the main server

Likely something wrong with the synbath data:

gmt grdcut -R-95/-94/-1.5/-1 @earth_synbath_30s_p -Gtemp.nc
gmt grdinfo temp.nc -C

It gives:

temp.nc	-95	-94	-1.5	-1	0	0	0.00833333333333	0.00833333333333	120	60	1	1

as you can see, the min/max values of the dataset are 0.

gmt grdimage @earth_synbath_01d -png map gives:

Can confirm. Checking with @Esteban82

I can confirm the issue

I try with the files that I upload to the test server and I got the same result. I also check another grids (earth_relief, gebco) and there was no such problem.
So I think that I there was a problem when the data was proccessed (i.e. when I run make earth-synbath). I could try to do it again tomorrow to see if I got the same result.

I'll see too

Hi @PaulWessel.

I ran the script srv_downsampler_grid.sh again and I get the same wrong grids. I didn't get any error message.
I think that the problem is generated with:

gmt grdconvert ${SRC_FILE} ${DST_FILE}=${DST_MODIFY} --IO_NC4_DEFLATION_LEVEL=9

I tried the 15s_p.grd that is created and it already wrong. The original grid it is ok.

I tried with GMT 6.4 on windows. Maybe there is an issue that was already fixed (but in this case I don't know why it didn't happend with the other grids).

Could you try to run it?
