Dear colleagues,

I am searching for a comparative study of models that derive direct and
diffuse solar radiation components from total solar radiation. I have
been using the Reindl model for many years and I am reasonable happy
with it. But, I'd like to get a feeling what other models are available
and how they compare to Reindl. Any pointers would be appreciated.

Thanks a lot,

Christoph Reinhart, Dr. Ing.
