Please, can someone help me, I'm new here.
On the weather radar, how to convert the information in dBZ, to millimeters?
Thanks in advance.

First of all, I would like to thank you for your teamwork in interpreting data from satellites, radar and other ways of obtaining data and transforming them into maps and graphs, easy to see and interpret.
My question is whether they could add a line to clearly identify, for example: polar, Arctic and Antarctic circle line. Ecuador, and the two Tropics.
The news, days ago, of the heat wave above the Arctic Circle. If that line were visible when viewing the temperature map, it was easy to look and see where the heat came from.
It's just a suggestion. I'm just curious about weather events. Sincerely Paul
