* - 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.
