Which version of CLM is represented in ParFlow?

[Chase Dwelle]

I looked at the docs but couldn't find a mention of which version of CLM is represented in ParFlow. I'd like to know which physics are/are not represented by referencing the CLM docs.

Hi Chase,

To accommodate the coupling between Parflow and CLM, the CLM in ParFlow-CLM has been edited a lot relative to the origional verision.

Some information is perhaps useful for you to know the physics of CLM in ParFlow-CLM:

1. The history is: 15 September 1999: Yongjiu Dai; Initial code

2. Some papers:

Dai et al., 2003, BAMS, The Common Land Model

Maxwell and Condon, 2016, Science, Connections between groundwater flow and transpiration partitioning (supplementary)

Kollet and Maxwell, 2008, WRR, Capturing the influence of groundwater dynamics on land surface processes using an integrated, distributed watershed model

Kollet and Maxwell, 2006, AWR, Integrated surface-groundwater flow modeling: A free-surface overland flow boundary condition in a parallel groundwater flow model

Hope this can help!

Chen

P.S.: welcome comments from other experts of ParFlow-CLM

Hi Chase-

 

Thanks for your question.  As I think I understand it (it’s a bit cryptic) you want to know about the physics in CLM.

To add to Chen’s great reply, we have carefully documented some (most) of the processes in peer reviewed publications in detail.  Here are some links below.

Thank you for the quick response. Diving into the references will be very helpful and should give me the information I need.

Best,

Chase
