Describe the bug
NLCD40 2011 dataset has an error in the index file where endian=little
This causes inaccurate landuse fractions. Dominate landuse does not shift, but fractional values to shift around that will result in differences in PX LSM simulations.

nlcd2011_ll_9s/index

To Reproduce
Steps to reproduce the behavior:

  1. run geogrid with index file endian=little and another endian=big
  2. Compare LANDUSEF arrays and there will be differences

** FIX ***
this should be removed "endian=little" or changed to "endian=big"

@coastwx Is this the same bug reported last December?

It is the same. We downloaded the recent version of WRF and the geogrid data maybe two months ago and the index file had endian=little.

That line can either be removed or specifically set to endian=big.

@coastwx The tar file on the server as well as on Cheyenne has been corrected.
