URL for downloading new weather data seems wrong

See original GitHub issue

While trying to use grib2json to get new weather data from NOMADS, I noticed that the URL format shown in the README here (and in the grib2json repo’s README) doesn’t load.

For example, this URL http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs.pl?file=gfs.t00z.pgrb2.1p00.f000&lev_10_m_above_ground=on&var_UGRD=on&var_VGRD=on&dir=%2Fgfs.${20140101}00 produces a 404 page that says: “Not Found: The requested URL /cgi-bin/filter_gfs.pl was not found on this server.”

While I try to figure out how the NOMADS file serving format has changed, I figured I’d let people know here, and if someone already knows the new format then they can provide it.

This is the command you’ll need:

curl "http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_1p00.pl?file=gfs.t00z.pgrb2.1p00.f000&lev_10_m_above_ground=on&var_UGRD=on&var_VGRD=on&dir=%2Fgfs.${YYYYMMDD}00" -o gfs.t00z.pgrb2.1p00.f000
