Help with adding my own input data to the models

[Drakso]

Hey everyone,

I am trying to add my own input data for a model to run on. I am using Aurora 0.25-pretrained as an example. The problem is, when I try to provide the folder where the files are located, with the --file argument, it has a problem with the file it self, even though the correct variables are loaded and is downloaded into grib format, from the ERA5 dataset. The only difference is the timespan of the measurements. I tried with data for 2 days and played with 6h data, 3h data and hourly data. I am already using aurora results from Open data, but I wanted to try and provide ERA5 data myself to see what the difference is, and whether or not different timespan will affect the result. Is there any limitations which I need to follow when providing input data? And if so, is there any documentation pointing to that?

Limitations for input data depend on the model,

• the params it expects
• prior times to begin forecasts with
• levels

I would suggest checking out each paper, and the implementations within each model for more information.
Aurora, using the cds input will already be using ERA5 data.
