Most of the parameters related to BATS1E are in file BLOCKDATA001.F
In this block data subroutine, almost all the 1-dimensional arrays
with the size of 20 are the BATS parameter, and there are 20 type of
vegetation. (desert type ranked number 8). For example,

c ******      kolsol is soil color type (see subr. albedo)
       data kolsol/5,3,4,4,4,4,4,1,3,3,2,1,5,5,5,4,3,4,4,4/

kolsol=1 for both desert and semidesert.

The different color will have different value of albedo (in albedov.F).

You need read BATS1E documents for the details.
