Wet Bias in seasonal run

Hi,
I am doing a seasonal simulation over Nebraska. The resolution of my inner domain is 3 km. Therefore, I am not using a cumulus parameterization.
And I am using WSM6 for microphysics. Unfortunately, I am getting very high precipitation values (3000 mm for JJA) over the irrigated area (i.e., where the model has a high irrigation fraction value). I am doing two scenarios (with irrigation and without irrigation). I am getting high value for both of them.
It would be really kind if I could get some suggestions for that.
 
Hi, and apologies for the delay. If you're still experiencing this issue, will you attach the namelist.input file you used for this simulation, as well as a plot or two to show the values you're getting? Thanks!
 
Hi, I am using NOAH LSM irrigation scheme and chose sprinkler method. Which adds the irrigation water in the RAINNC. However, I am having trouble in controlling the amount of water added as irrigation. I have added my namelist.input. I was trying to apply 8 mm per day. howver, it is applying 24 mm per day. Besides, I am also having trouble in seperating natural precipitation from the irrigation water added as precipitation.
