WRF_Noahmp_Crop model yield assessment

Dear all:
I was trying to test the WRF_Noahmp_Crop model in China, in wrfout there is a variable named "GRAIN (g/m2)".
I have 2 questions:
(1) if the maximum GRAIN during the grow season is the finall yield of the crop or all the GRAIN results should be accumulated to represnt the crop yield?
(2) what should I do if I want to compare the simulated crop yield from the WRF_Noahmp_Crop with the statistics, is there a conversion coefficient between the simulated GRAIN with the actiual yield?
Thanks for anyone who may concern.
Looking forward for constructive relies.

Wangyan,

Please see my answers below:

(1) if the maximum GRAIN during the grow season is the finall yield of the crop or all the GRAIN results should be accumulated to represnt the crop yield?

maximum GRAIN during the grow season is the finall yield of the crop

(2) what should I do if I want to compare the simulated crop yield from the WRF_Noahmp_Crop with the statistics, is there a conversion coefficient between the simulated GRAIN with the actiual yield?

I am not sure how to do so. Please refer to the literature for helpful information.
