[gradsusr] Hello to all users

Avi --

Go to the link you provided below and, within the browser, check the layers (500 mb, surface, others you may want), then check the variables that you want, (SLP is “PRMSL”).  Put in a latitude/longitude range if you don’t want global data.  Then, under “View the URL”, click the “Show URL…” button then click “Start download”.

You should get a URL that has your custom request.   You can use this URL as an argument for curl (or similar program) as…

curl  http://...  > gfsdata.grib2

What comes back is in grib2 format.  Depending on your shell, you may need to do some quoting of the URL to get the command to work.   Using the Unix tcsh shell, I had to put the URL in double quotes.  This is a great way to download limited subsets of the GFS or other large modeling datasets.

Subject: [gradsusr] Hello to all users

Will someone please explain to me how to download from this site grib files in the attached link:

http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl?dir=%2Fgfs.2015122212<https://urldefense.proofpoint.com/v2/url?u=http-3A__nomads.ncep.noaa.gov_cgi-2Dbin_filter-5Fgfs-5F0p25.pl-3Fdir-3D-252Fgfs.2015122212&d=CwMFaQ&c=DsZY2bea7iNIzyp-7sZ0t0F2UfNQZUfZhEPCv_2wBI0&r=VuUP78D2VHO8ziN7eh-DsCgmMeBUeha5u93niBuCCaE&m=QsISXMj0lDqlHgjwbZa-Yqc6UrSsTLL7egjerYCQ0WA&s=upuKHtVOXRCIjp5WHlRbcngtFkL-myTgpBXZBl3IPso&e=>


Suppose I want to download this data :
H 500
SLP
T500
T700
T850
etc......

How do I do it, I tried it several times but I could not get the grib files?

Regards
Avi.
