How to choose sigma values?

[NisKarki]

Hi,
From your config file, I see that you set the following values for sigma:
psl: 0.1692666615037876
tas: 0.0425178630338289
uas: 0.3268027589410125
vas: 0.3268027589410125

Could you share how these values were chosen?

Hi, thanks for your question!
Those numbers are the result of a very simple (random-search) model selection. As a criterion we looked at error and uncertainty calibration on a selected subset of the available data set.
