Could you improve the unfrozen soil water in Biome-BGCMuSo based on its empirical relationship with soil temperature? #5

Hi! I am interested in the Biome-BGCMuSo model and want to use it to model biogeochemical process in areas with freezing and thawing process (FTP). However, it seems that the current version has not considered FTP, which makes a great difference in simulation of soil water and subsequent other processes such as decomposition of the SOM . As a beginner, I am not good at C language and modify the model but I have to use the model. Thus, I sincerely expect to get help from you. As I know, there is a simple power function between unfrozen soil water and soil temperature as following: unfrozen_SWC=a(Tf-Ts)^b where a and b are two empirical coefficients associated with soil type. The details can be found in "Frozen soil parameterization in SiB2 and its validation with GAME-Tibet observations". I would appreciate it if you could make some adjustments in the above aspect! if it is infeasible, what should I do to make the results are more accurate in frozen soils? I am looking forward to your reply! Thank you very much

Hi @yuanhongdeng thanks for your note. Since you reference Biome-BGCMuSo specifically...

Any thoughts @zbarcza ?

My colleague started email communication about the topic with Yuanhong Deng. We will see how can we address this issue.

My colleague started email communication about the topic with Yuanhong Deng. We will see how can we address this issue. Dear Professor, Thank you for your responses! I am sorry to bother you again, and congratulations to your team on the publication of the essay ,"Soil-related developments of the Biome-BGCMuSo v6.2 terrestrial ecosystem model"！It is a very nice work! My question is still about the freezing-thawing process in the model. I don't know whether it can be considered in the Biome-BGCMuSo v6.2 now? or what I can do to overcome this? It is really important when this model is used to stimulate the hydrological processes in the frost soils, which is heavily affected by the freezing-thawing process. Thanks for reading! I am looking forward to hearing from you! Yours sincerely, Yuanhong Deng
