<div dir="ltr">Hi Dennis, <div><br></div><div>Thanks for your response. This isn't an NCL specific question, but I don't see any tools that could allow you to download only specific variables from a large remote netcdf file. </div><div>I'm looking a downloading lots of large files (~1GB), of which I only need a small percentage of the variables included in the file. </div><div><br></div><div>I know with the NOAA grib files, there are some tools (scripts) that let you only download the specific variables. I believe this is done by figuring out the specific lines that are needed in the files, and only parsing those lines. I didn't know if there was some standard way to do this with netcdf. Thus far, I've come to believe there is not, but figured this community would be a good place to ask. </div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jun 10, 2019 at 1:35 PM Dennis Shea <<a href="mailto:shea@ucar.edu">shea@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><br></div><div>re: " ... <b>only downloading specific variables of a NetCDF file"</b></div><div><br></div><div>The question is unclear.
