Dear Graziano Giuliani,

I am so sorry to bother you but I am seriously confused with soil moisture's unit.

I have followed your instruction of soil moisture's unit in both RegCM4.2 and RegCM4.4.5.7. As you mentioned, the correct unit of measure in the model which was corrected is kg/m^2 (or mm). However, the values I got from these versions seem to be wrong with the unit. 

To make it clear, I would like to indicate the results I received from these models in updating soil moisture simulations (please find in attached file). This is the case for no update soil moisture for the regional 100-115E 7-24N in 2012.

Would you mind telling me the reasons for these differences between 2 version of RegCM?  
Thank you in advance.

Regards,
Thanh Huyền
