How is level 1b data calibrated or corrected from level 1 data? (When trying to process level 1 data to get level 2 SHI)

Hi everyone,

I found this amazing radar data source and playing around with it recently.

I am a GIS student and interested in analyzing weather data. However, I don’t have many experiences in radar data processing. So I was curious about the workflow of processing radar when I explore the datasets. I tried to get hailstorm data and have these questions:

I try to use pyhail to transform level 1 data to level 2 SHI (severe hail index) data. But it seems like the original pvol data (DBZH) in level 1 needs to be calibrated or corrected into level 1b. How could I do that?

Thanks in advance!
