Hi Hsie,

Here is a listing that contains volumes of various feeds available in the
IDD:
Data Volume Summary for idd.unidata.ucar.edu
Maximum hourly volume 5880.553 M bytes/hour
Average hourly volume 4203.884 M bytes/hour
Average products per hour 194633 prods/hour
Feed Average Maximum Products
(M byte/hour) (M byte/hour) number/hour
CONDUIT 2349.260 [ 55.883%] 3721.929 56166.114
NEXRAD2 911.864 [ 21.691%] 1149.017 58948.523
NGRID 306.645 [ 7.294%] 734.995 10616.909
HDS 194.650 [ 4.630%] 421.364 18627.341
NNEXRAD 175.419 [ 4.173%] 208.484 23738.000
NIMAGE 154.132 [ 3.666%] 327.339 168.864
FNEXRAD 62.948 [ 1.497%] 85.080 70.773
UNIWISC 20.525 [ 0.488%] 31.961 23.750
IDS|DDPLUS 18.816 [ 0.448%] 22.790 26094.136
DIFAX 5.512 [ 0.131%] 21.983 6.841
GEM 2.023 [ 0.048%] 22.248 139.636
FSL2 1.951 [ 0.046%] 2.086 22.182
NLDN 0.142 [ 0.003%] 0.416 9.659
As you can see, the NOAAPORT NGRID feed, which is composed of higher resolution
model data mostly in GRIB2 format, has twice the volume of the HDS feed on
average. Another way of looking at the NGRID volume is that it is roughly
75% of the volume of the combination of the NNEXRAD, NIMAGE, FNEXRAD, UNIWISC,
IDS|DDPLUS, DIFAX, GEM, FSL2, and NLDN datasetreams. So, the addition of
NGRID to the mix would be significant if you are already having bandwidth
problems on al.noaa.gov machines.
Ingesting and processing of the NGRID feed products is, of course, entirely
up to you. I only asked about getting the feed on stratus if you were
already ingesting it on another of the machines in your control.
