Stefan,

      I believe there is no document available for these formulas. Most 
formulas in the IDV were created by Don in Jython or Java, and I believed he 
referenced those formulas in the GEMPAK. With limit resources here, it is 
unlikely to spend more time to create the document for these formulas. However, 
I can provide more details information for specific formula if the request is 
raised.  Sorry about the inconvenience.
