Literature references for values in VEGPARM.TBL?

Dear WRF-Community,

I am conducting a sensitivity study over Colombia to assess impacts of land cover change. Now I ran a deforestation scenario, i.e. replaced evergreen broadleaf forest for my whole domain by dryland cropland and pasture following this post https://forum.mmm.ucar.edu/phpBB3/viewtopic.php?f=76&t=169&p=328&hilit=vegparm.tbl#p328. I am using USGS-24-class-classification.
My simulation led to a small cooling (-0.2°C) over deforested areas compared to the CTRL simulation. I am now looking for a plausible answer to that and was wondering, where the values in the VEGPARM.TBL come from and if there are any literature references to that.

Thanks in advance,
Astrid
 
Hi,
Please take a look at the website below and see whether you can find some helpful information.

I talked to our experts in NCAR and I was told that many of these parameters are specified based on in-situ observations. However, the representativeness of these values is still questionable because the in-situ observations are quite limited.
 
Hey Ming,

thank you very much for your answer! Ok, that is good to know!
I am still wondering if this is the actual reason for the cooling, because my control-simulation is reproducing quite well temperature and precipitation when compared to observational values.
But I'm on it, thanks again!
Astrid
