Can you please add a higher resolution ECMWF model? It's the most important model globally.

The full-resolution ECMWF IFS model at 9 km resolution is not available as open-data. A license from ECMWF is required to use this data. Those license terms also forbid redistribution.

However, past data of the ECMWF IFS model at 9 km is integrated into the historical weather API at Open-Meteo. There is strictly no forecast available and data has a delay of 2 days.

Thanks. I understand now. What about UKMO Model?

Update: UKMO models are now available https://open-meteo.com/en/docs/ukmo-api

UKMO does not offer any open-data anymore. It is possible to purchase data, but their pricing model per GB is very costly if you are interested in global coverage with a reasonable amount of weather variables. I contacted UKMO multiple times, but never received a reply. The BOM ACCESS models, that are integrated at Open-Meteo, offer similar forecast data as they are also based on UKMO models. Could be a good alternative

Thank you so much. One last question. I see that best_match isn't accurate in some regions in temperature especially in Middle East area. I don't know what the model is. Should you add model name in the response?

For which locations exactly? Either ICON-EU or ARPEGE are used. Yes, I am planning to provide more information about which model is selected. I would also like to implement a better system to select weather models for different regions

In Saudi Arabia the temperatures are not accurate in some places (different 1 to 2 degree Celsius)

Not like the full-res ECMWF. But in Europe it's accurate.

Hi,

I use self-hosting on Ubuntu22. What's the cmd in order to download the new ECMWF model? For the older one, I used the binary with arguments <exe> download-ecmwf --run 00

(It runs at 00, 06, 12, 18)

Also, for the ECMWF IFS, it is not supported to only download a subset of weather variables, but all variables need to be downloaded. Is it the same for the new model with a resolution of 0.25°?

Thanks in advance for your help.

The command is `openmeteo-api download-ecmwf --domain ifs025`. Downloading a subset of weather variables is supported using `--only-variables`.

Hi Patrick,

I get an error:

root@ubuntu:/var/lib/openmeteo-api/data# openmeteo-api download-ecmwf --domain ifs025

App/DownloadEcmwfCommand.swift:43: Fatal error: Could not initialise domain from ifs025

Illegal instruction (core dumped)

'openmeteo-api download-ecmwf --domain ifs025 --only-variables temperature_2m' returns the same error.

It's an ubuntu 22.0.
