Conversion of Z values

How to convert Z in dBZ to mm6m-3 ?

Hi @MohitDahliya,

To go to linear Z use:
z_lin = 10.0**(radar.fields['reflectivity']['data']/10.0)

Cheers

Yes but if you take like this, that means you are taking Zo = 1. So is that correct..?

Yes, this conversion assumes Zo = 1 mm^6 m^-3.

But Is Z really around 1 mm^6mm^-3 ? Because I am getting some under values using this formula as it is...

This is the official American Meteorological Society (AMS) glossary definition and method as well. We typically use the community standards/peer reviewed standards, which in this case, is the AMS.
