Hi Developers!
I looked at the road conditions that are used in the subroutine RODCON
in lib_therm.f. Dew is numbered 5 while ice/snow is 3 and mix
water/snow is 4. During each output period, the highest road condition
is chosen. Why is dew so high? Shouldn't ice/snow be more serious and
chosen before dew?
Best wishes,

Hi Esben,
It is like that because dew on a surface under 0°C causes black ice. And
black ice is worst than ice/snow or water/snow.
Cheers,
Miguel
