The loop index is wrong in the following snow initialization part in Noah-MP: https://github.com/MPAS-Dev/MPAS-Model/blob/41e9a3fb8ca6b9250a7405209a5c60996318409f/src/core_atmosphere/physics/physics_noahmp/drivers/mpas/NoahmpInitMainMod.F90#L53 It should be from its to **ite**. currently it is from its to **its**. This bug needs to be fixed as soon as possible.
