[Dhsvm-users] Effective LAI July 0.000000

[Keith Adams]

Dear DHSVM Users,

I have just completed a run of a model created using DHSVM 2.0.1.
In the output to screen I got all effective LAI of zero (or possibly 
less than 0.0000005?), as below.

***
Vegetation Type: Horticulture on Warkworth Clay
2meter    wind speed fraction of ref level 0.220162
Overstory LAI July 4.870000 Effective LAI July 0.000000

Vegetation Type: Horticulture on River Flat Clay-Loam
2meter    wind speed fraction of ref level 0.220162
Overstory LAI July 4.870000 Effective LAI July 0.000000
***


Does anyone know why I am getting "Effective LAI July 0.000000"?


I have 9 vegetation types with overstory, and I got the same for all of 
them - Effective LAI July 0.000000.
The model run seemed to work OK in general, but evapotranspiration is a 
bit low.

I have searched through the usergroup emails and couldn't find anything 
relevant.
I did notice that output in one email (16/01/2008) had very large 
negative values.

Any suggestions would be much appreciated.

Regards,
Keith Adams.
