[RegCNET] urban net longwave radiation error: no convergence

[Michal Belda]

Hi,

I've been getting the same error with my simulations. Now, I don't have 
a solution for you, however, I've traced the error back to the 
UrbanRadiation routine, in which the variable t_grnd is NaN. The NaNs 
then propagate to other parts like the multi-reflection loop in the 
net_longwave subroutine, essentially creating an infinite loop, thus no 
convergence of the algorithm.

In trying to track the NaNs to where they originate, I found out that 
some emerge in the radabs subroutine, but haven't yet been able to 
ascertain if that subroutine is really the culprit.

Hope this helps a bit...

Cheers,

Michal
