[RegCNET] how to change BATS parameters in RegCM3, such as maximun fractional vegetation cover

[Jonathan Winter]

Using the grep command is probably the best way to find specific
variables.  Since you're looking for albedo:

grep 'albedo' *

is a good start.  Do this in both the Main directory and the
Main/Commons.  Find out more about grep by typing: 

man grep   

Regarding the specific variables you mentioned:
albvgs - vegetation albedo for wavelengths < 0.7 microns
albvgl - vegetation albedo for wavelengths > 0.7 microns
vegc - maximum fractional cover of vegetation

In the newest version of the model these variables are located in
BLOCKDATA001.F

Tundra, A. Irrigated Crop, .... ). I want to change the parameters in BATS vegetation cover, meanwhile keep the vegetation type in region.
