Herbie 2024.3.0

ECMWF shared this exciting news a few days ago about their open data products for the Integrated Forecast System (IFS)

ECMWF now provides a much larger open dataset to the public, representing weather forecasts at a higher resolution and a reduction in some release times.
- ECMWF: Media Centre

This Herbie release updates the ECMWF model templates to access the new IFS and AIFS 0.25 degree datasets. Historical access to the 0.4 degree datasets is still available for dates before February 1, 2024. Thanks @alcoat!

Deprecation

Now that ECMWF provides open access for two different models, the argument model='ecmwf' is deprecated. Instead, you should access the Integrated Forecast System (IFS) with model='ifs' or model='aifs for the Artificial Intelligence IFS.

- Herbie('2024-3-1', model='ecmwf')  # Deprecated

+ Herbie('2024-3-1', model='ifs')

  Herbie('2024-3-1', model='aifs')  # New Model

New Feature

Herbie has two new experimental functions that may be helpful to some people.

• HerbieLatest Find the most recent available model run.
• HerbieWait Wait for a particular model run to become available.

You can see examples in the docs: Herbie Latest Data.
If these are helpful to you but you want them to be improved, I'm looking for people to help make these better, (along with FastHerbie which could use some work too).

Herbie at the American Meteorological Society

I gave a talk on Herbie at the American Meteorology Society in January. You can see my slides here. Soon, you should be able to go to the conference website and watch the recorded presentation.

It was a lot of fun talking to some of you at AMS this year. Its always a surprise to me when I'm wandering around the poster hall and someone says, "Hey Brian, Herbie was used to make this poster!" Thanks everyone for your kindness.

Please feel free to open issues when you see problems, share how you use Herbie in the discussions, and feel free to contribute your ideas and PRs.
