Re: [ferret_users] THREDDS server, where is the main work done?



Hi Martin,
I've asked the question on the netcdf group email list, and I'll pass along the answer.

Good morning,

I have a question concerning the data flow when data are stored on a THREDDS server.

After opening an opendap connection to a THREDDS server

use "http://.......";

i do some operations and write data to a local disk.

let aaa= ....

repeat/l=1:1000 save/append/file=outputfile.nc aaa

I know, data on the THREDDS server are in netcdf-4 format, using compression. My question is, where
the decompression takes place:

- at the THREDDS server and the uncompressed data are delivered over the web, - at the local machine, the compressed data are delivered over the web and are uncompressed at the local machine?

Greetings,
Martin Schmidt
