I have a problem about the RegCM4.1 model. In my research region, when I used the ERA40 forcing data with a script, it can be sucessful. However, I used the NNRP1 as the forcing data, the same script can not be sucess in the same research region. The error is below: Even if I decrease the dt, it can not be effect. So I wtite this e-mail to help. Thank you!
