Hello,
I am attempting to code the parametric scheme for soil thermal conductivity from the Peters-Lidard approach (Peters-Lidard et al., 1998) to the De Vries method (De Vries, 1963) in the Noah-MP land surface model of WRF 4.6.1. The De Vries (1963) method divides soil components into mineral particles, organic matter, liquid water, ice, and air.
However, there is no organic matter in the soil parameter table.
The carbon subroutine identified parameters such as fine root mass, stem mass, STBLCP, FASTCP, and others. When calculating the organic matter fraction in the thermal conductivity parameterisation process, should the stable and fast carbon first be converted into organic matter mass and then into a volume fraction? Alternatively, the empirical values of organic matter in different types of soil could be entered into a soil parameter table to obtain the required values. Are there any other scientific methods of obtaining the organic matter fraction of the soil?
What should I do?
