ECMWF 0.4 degrees resolution forecast data will be deprecated in May 2024 #285

Closed cole-p closed 7 months ago

cole-p commented 7 months ago

ECMWF has added a section to their Open-Data docs indicating that products produced at 0.4 degrees resolution will be deprecated in May 2024. After that time ECMWF will switch over to only providing data at 0.25 degrees resolution.

From a quick glance in the ECMWF S3 bucket, ECMWF appears to have been publishing data at both 0.4 and 0.25 degrees resolution starting on 2024-01-31T06:00 UTC.

Currently the resolution is hard-coded in the version field of the ecmwf class.

Thanks for sharing this news! Yeah, let's get this in Herbie 😄 I'll set aside some time in the next week to review pull request

completed in #283. Feel free to provide any more comments and PRs on the topic if you see anything.

283 makes this change

First, model can be either ifs or aifs, not ecmwf

# Deprecated
Herbie(date, model='ecmwf')

# New
Herbie(date, model='ifs')
Herbie(date, model='aifs')

Also, you can specify resolution in model='ifs' so you can still access the historical data

Herbie('2024-02-25', model='ifs', resolution='0p4')

I'm going to update the tutorial notebook in the docs and publish a new Herbie release this weekend.
