Potential for failed submission between 19th to 22nd March

Dear all,

Over the weekend a file containing all registered model names became blank. Therefore, forecast submission was halted as we couldn’t check whether the model name submitted was registered on our system. Rest assured, we are working hard to get this issue fixed.

As this issue is on our end, forecast submission is welcome via email. I would recommend using the following Python code:

from AI_WQ_package import forecast_submission

# Create an empty DataArray 

tas_p1_fc = forecast_submission.AI_WQ_create_empty_dataarray('tas', '20260319', '1', <<teamname>>, <<modelname>>, <<password>>) 

 # Populate the DataArray with forecastprobabilities 

tas_p1_fc.values = tas_p1_fc_pbs

# save netcdf

tas_p1_fc.to_netcdf(f"{save_dir}tas_20260319_p1_<<teamname>>_<<modelname>>.nc") 

Here, I have focused on temperature predictions for the first forecast window as an example. Please then send the saved netcdf files to joshua.talib@ecmwf.int .

We will contact all relevant teams where forecast submission was missed over the weekend. On the website, you can check whether your forecasts went through at 12 UTC using the participation tables on each individual teams page.

We are sorry for the inconvenience caused.

Kind regards,

Josh
