HOTFIX: Migrate Forecasts to UCAR THREDDS by MateusStano · Pull Request #943 · RocketPy-Team/RocketPy

MateusStano · 2026-03-19T01:30:05Z

Summary

Solving #933

We are now using OpenDAP with UCAR THREDDS:

Used for GFS, NAM and RAP. This works mostly exacly the same as we were doing with NOMADS. Just now we are getting from a different server

The following models are not available on THREDDS and were deactivated

GEFS
HIRESW

Particularly GEFS is very important for Monte Carlo simulations and we should look for alternatives as fast as possible

Observations

The Thredds OpenDap approach took me a long time to find information about. So in between I tried out other methods which will still be important for us to understand for the future (probably for re-implementing GEFS):

GRIB2 filter via NOMADS: this adds a few new dependencies do RocketPy (which are in total bigger in size than RocketPy), It is quite hard to code but can be done, probably the best way to move forward with re-adding GEFS, but including the added libraries as optional dependencies
Siphon: python library that would also add a bunch of dependencies, that are even bigger than the Grib2 method would require

THREDDS actually has an archival version of GEFS that goes up to 2020. I think we can find other alternatives, but this could be a last resort option.

THREDDS catalog: NSF and NCEI
- There are a few models that we can add with this (HRRR and AIGFS)
