Model Request: ConUS NOAA NBM Model
-
I was clicking around on the info tab on models at Ventusky.com, and saw they had an interesting model listed: "NBM," which I looked up and is written up here:
https://theweatherguy.net/blog/basic-info-about-the-nbm-and-icon-models/
and:
https://vlab.noaa.gov/web/mdl/nbm
It can be considered an ensemble derivative of HRRR that includes inputs from a pretty extensive list of weather models from all sorts of organizations to tweak the output. The most common thing I'd be doing is comparing the two looking for divergences to assess model sensitivity, with one model as my default...probably NBM, assuming it lives up to its promise of improving on HRRR accuracy.

This NBM model is to some extend similar to the Meteoblue model which is a consensus model using 15 models. The differences with NBM are:
Meteoblue is available worldwide.
Meteoblue provides only point forecast data, but not gridded data allowing to feature maps. -
@idefix37 Sort of...but the fact that NBM is principally HRRR, and updated every hour at a high resolution with a brief forecast depth, satisfies a very different use case. The closest thing to a duplicate is HRRR itself.
The main thing that could be said to be the same about Meteoblue and NBM is they are ensembles, but not much more.
-
Update: I've recently been using Ventusky to compare NBM and HRRR results, and there are divergences and I think it does add something. I posted some screenshots but I think the board rejected their file size.

2025, would still like NBM added
