PlaSim/scripts

*burn.sh v1.0*
--------------
Afterburner cmorizer
Extracts variables from PlaSim output using CMOR conventions.
Adjusts variable names, signs, units and computes derived variables.

Usage: burn.sh [options] infile outfile var
Options:
-h Prints this help
-s Extract 3D variables on sigma levels
-a Afterburner variable (do not cmorize)
-p lev1,lev2,... Specify pressure levels (in hPa)

Default pressure levels are 20,30,50,70,100,150,200,250,300,400,500,600,700,850,925,1000 hPa

Variables not in this list are extracted directly using afterburner with no change.
Examples: zeta,d,bld etc.
Note: uas and vas are not available in PlaSim output, derived from ua and va at sigma=1
Note: psl (sea level pressure) is not avaiable in PlaSim output,
derived from huss (hus at sigma=1), tas and ps using the hypsometric formula
