calculation of saturated frozen thermal conductivity of soil

[yis2@mcmaster_ca]

In module SoilTemperatureMod of Community Land Model 3, there a line to calculate saturated frozen thermal conductivity of soil,


> dksat = tkmg(c,j)*0.249**(fl*watsat(c,j))*2.29**watsat(c,j)
>
> 2.29 is for thermal conductivity of ice
> 0.023 for air
> 0.6 for liqid water

what is 0.249 for.

Thanks

Hi,

Hopefully you'll get lucky and find an answer here, but since you've posted a land model question to the atmosphere model bulletin board, you may not. If so, please contact the land model liaison or post to one of the CCSM bulletin board categories.

I move this question to CCSM part.
