I am preparing some notes on the WRF Physics schemes. I wish to have
information that
will ensure the appropriate use of the schemes. I am using the schemes in
I should be grateful if you could address the following questions/issues
about any of the schemes for me. I am willing to make the information
available after the compilation.


WRF Physics Schemes (WRFV3.2.1)
The objective of this  is for the following issues to be answered for each
1. What was the objective for with which the scheme was developed?
2. What temporal scale was it developed for?
3. What kind of weather phenomena was it developed for?
4. What spatial scale or resolution was it developed for?
5. Any other information to ensure appropriate use of the schemes
6. Include appropriate references
