* - A newer version of CLIGEN includes quality control algorithms. The processing is described in the paper Implementing quality control on a random number stream to improve a stochastic weather generator
** - The WEPP winter processing changed significantly in model version 2008.907. A preliminary update describing the changes is available here.
***- The WEPP subsurface hydrology changed in model version 2006.5. A document describing the changes is available here.
**** -The WEPP channel routing was expanded in model version 2012.8. A paper describing the updates is available here. A description of the required chan.inp file is available at: chan.inp format
