You have raised a very important issue. Because the regional downscaling becomes an important subject (mostly due to societal planning pressure), a lot of funds has been spent on this. People without adequate training in the field rush to this field. They just run the models then announce the results without appropriate scientific understanding. In my opinion, the type 4 downscaling is a scientific issue, it certainly needs scientific research. But taking it as a solved problem (push the computer bottom then announce the results) really will eventually hurt the society and science.
Thanks for taking the lead on this.
