Dear all,
I am trying to simulate the Lightning Flashcount of ESCS cyclone over the Indian Ocean region and its related namelist attached below. But, in the output, I got zero values for both IC Flash counts and GC Flash counts. Why it's happened? I did any mistake? Please provide your valuable suggestions and help.
Kindly help me out.
Thank you.

I looked at your namelist.input and all look fine except a few options below:
cellcount_method = 1 , which is better for large domain
iccg_method = 2, which avoids possible issue related to unreasonable iccg_prescribed_num and iccg_prescribed_den
Please try and see whether you can get IC and GC flash counts.
Thank you for your quick reply. I modified the namelist file by adding above mentioned variables. But, it still showing zero values. Are there any other modifications are needed for the Asia region?
I am not aware of other options ...
I have sent your question to the developer. I will keep you updated if I get any feedback.
