Dear Graziano Giuliani,
Thank you for your reply with detail explanation.
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,
