Missing erosion files WPS_GEOG

Hi, I'm trying to set up WRF-Chem from scratch. I've compiled successfully but when trying to run a test simulation, I'm failing at WPS.
It seems that the erosion factors are not contained in the WPS_GEOG folder.
They are not available from the general WRF downloads page in the geog data.
The tutorials (http://ruc.noaa.gov/wrf/WG11/tutorialexercises.htm) direct me to the ftp site at noaa, but the folder is missing (ftp://aftp.fsl.noaa.gov/divisions/taq/d ... 3/erod.tar).
Any idea where to get these from, or can anyone send them to me?
Many thanks,
Helen
