Madagascar oceanography help

[Juliano Dany]

Dear,
I am a researcher from National Oceanography Data Center of Madagascar. I need to download five years NetcdfSubset (parameter: sst, sss, ssh, msla) but I meet some problem about the downloading. Please, someone can suggest me to obtain these data or I appreciate if you can send that to me by SendSpace or other.
Thousand thanks in advance, my research depend totaly on your positif answer.
Looking forward to hear from you as soon as
Best regard

Juliano,
What methods for download have you attempted other than NetcdfSubset?
Please expand your parameter/variables list (sst, sss, ssh, msla) so that we are clear on what you are looking for.

What 5-year period/range are you interested in obtaining (specific start/stop dates)?

Are you interested in the entire global domain, or on a sub-region (specific lat/lon bounding box)?

Juliano,
Your "Time Range:" in NetCDFSubsetService (NCSS) needs to be a "single
day" when selecting this number of variables (all those you selected
add up to several megabytes/gigabytes. multiply that by x days and you
have a HTTP get request that can exceed the server limit of 4GB).

i.e., ideally for the "Time Range", Starting = Ending. Search for
"wget script" in the HYCOM.org forum for examples.

You could try only requesting "one variable" per request and then
including the time range of your choosing (the smaller the better).
This would serially be opening up several files in the same directory.
The more variables you select, the more background server-side
processing is required (which we have a a finite amount of).

Then keep the same time range and bounding box, uncheck mld, and move
onto ssh, etc. You will notice a slowdown for salt, temp, u, & v
variables since these are 3d vars that have a depth component. So you
might not be able to perform the same time range request for these
variables. You will need to experiment (NCSS is not perfect).
