Hi Felipe,

This should not be anything to worry about.  This is a typical occurrence in CLM output.  To be certain, I have asked a CLM-developer colleague of mine (Dr. Jinyun Tang), and he indicated that this message often appears because of rounding errors.

Kind Regards,

Hi Friends,

I´m using RegCM-4.1. Anyone knows what could cause an error in subroutine BalanceCheck (~/Main/clm3.5/src/biogeophys/BalanceCheckMod.F90)? This warning doesn´t stop regcm, but is it a critical error? Should I worry about it?
This subroutine accumulates the numerical truncation errors of the water and energy balance calculation. It is helpful to see the performance of the process of integration.
The error for energy balance = abs(Net radiation - change of internal energy - Sensible heat - Latent heat)

 soil balance e nstep =     49500 point =  5456 imbalance =    0.00 W/m2
