Detailed Description

Simple PBL diffusion package for ICAR

Local-K diffusion type PBL as in Louis (1979) as documented in Hong and Pan (1996) = HP96 Hong and Pan used this for their free atmosphere diffusion, but noted differences used in the "current operational model" notably the asymptotic length scale lambda

 HP96 = Hong,S.-Y. and H.-L. Pan (1996) Monthly Weather Review v127 p2322
       Nonlocal Boundary Layer Vertical Diffusion in a Medium Range Forecast Model

 Implemented with K,shear,stability... on half levels
  rho on half levels for f=k*rho*dq/dz*dt
  rho on full levels for q=q+f/rho
   q,U,V on full levels
