 I have been studyed the MOD16 algorithm for about 2 years. I have analysized and validated it in cropland (YES) in North China Plain, and I found some problems with the algorithm, especially about the parameterization of aerodynamic resistance and canopy resistance, which resulted in the estimated result far from the ground observations in the winter wheat field. Maybe, this is one of reasons why MOD16 product is now released. Now I am trying to modify it.
 If someone is interesting in it. I am looking forward to discussion with you. My email, sunzhigang.sun@gmail.com
