Dear all,
I am currently running a reginal CLM case (I2000Clm50BgcCruGs). I used my own forcing dataset and domain maps. I am doing a 500-year spin-up. However, a quadratic error showed up after 100 years. In the cesm.log, it says "ERROR: Quadratic solution error" b^2 - 4ac is negative".
I looked up the guide and checked the similar questions in the forums. It probably resulted from the forcing dataset. However, I compared my dataset with GSWP dataset. All max, min, and mean values are similar and in the same level in the same region. Hence, I have no idea what caused this problem. If it is the problem of my forcing dataset, how can I track the errors and find the specific position of the error values in the forcing dataset? Any solutions will be appreciated! Thanks!
