Question about surface and flux variables in UPP V3

I would like to obtain some information about the methodology used in UPP Version 3 to post-process the following variables:
INST SFC SENHEAT FX
INST SFC LATHEAT FX
INST GROUND HEAT FLX
SFC MIDDAY ALBEDO
FRICTION VELOCITY
ROUGHNESS LENGTH
SFC (SKIN) TEMPRATUR

I am planning on using the post-processed WRF-LES output for these variables and measurements of the same variables collected from a dense array of towers to do an assessment. The names of these variables come from the UPP control file "wrf_cntrl.parm". If anyone could provide this information or contact info for someone who can, I would appreciate this. I want to gain some understanding about how these fields are produced.

I also have a more specific question about the line pair in the control file for ROUGHNESS LENGTH which has a SCAL value of 2.7. I question this value since all the other variables have values like 3.0, 4.0, and 5.0. Just curious to learn if this is a typo error or if there was a specific reason for this value.

Thank you.
