The http protocol allows 'random access' reading;however, that means that we need an index file and a httpprogram that supports random access. For the index file, wecan modify a wgrib2 inventory. For the random-access http(s) program, wecan use cURL. Both are freelyavailable, widely used, work on many platforms and are easilyscripted/automated/put into a cronjob.

The basic format of the quick download is,
get_inv.pl INV_URL | grep (options) FIELDS | get_grib.pl GRIB_URL OUTPUT
INV_URL is the URL of a wgrib/wgrib2 inventory
ex. https://nomad3.ncep.noaa.gov/pub/gfs/rotating/gblav.t00z.pgrbf12.inv
grep (options) FIELDS selects the desired fields (wgrib compatible)
ex. grep -F ':HGT:500 mb:' selects ':HGT:500 mb'
ex. grep -E ':(HGT|TMP):500 mb:' selects ':HGT:500 mb:' and ':TMP:500 mb:'
GRIB_URL is the URL of the grib file
ex. https://nomad3.ncep.noaa.gov/pub/gfs/rotating/gblav.t00z.pgrbf12
OUTPUT is the name of the for the downloaded grib file
INV_URL is the URL of a wgrib/wgrib2 inventory
ex. https://nomad3.ncep.noaa.gov/pub/gfs/rotating/gblav.t00z.pgrbf12.inv
grep (options) FIELDS selects the desired fields (wgrib compatible)
ex. grep -F ':HGT:500 mb:' selects ':HGT:500 mb'
ex. grep -E ':(HGT|TMP):500 mb:' selects ':HGT:500 mb:' and ':TMP:500 mb:'
GRIB_URL is the URL of the grib file

The 'get_inv.pl INV_URL' downloads the wgrib inventory off the net and addsa range field. The 'grep FIELDS' uses the grep command to select desiredfields from the inventory. Use of the 'grep FIELDS' is similar to theprocedure used when using wgrib/wgrib2 to extract fields. The 'get_grib.plGRIB_URL OUTPUT' uses the filtered inventory to select the fieldsfrom GRIB_URL to download. The selected fields are saved in OUTPUT.
