LISOAL	LOGICAL	.FALSE.
XISOAL	ARRAY(REAL)	99*-1

• LISOAL : flag to interpolate on altitude levels the following variables: potential vorticity, wind, cloud (liquid water and ice) and precipitation (rain, snow and graupel) mixing ratio, dust extinction (if available). The outputs are 3D fields named: ALT_CLOUD, ALT_PRECIP, ALT_PRESSURE, ALT_PV, ALT_U, ALT_V and ALT_DSTEXT (if available).

• XISOAL : altitude of the isobaric levels

• LISOPR : flag to interpolate on pressure levels the following variables: potential temperature, wind, water vapour mixing ratio, geopotential (in meters). The outputs are 2D fields named with suffix ‘xxxxHPA’ where ‘xxxx’ stands for the pressure value

• XISOPR : altitude of the isobaric levels

• LISOTH : flag to interpolate on isentropic levels the following variables: pressure, potential vorticity, wind, water. The outputs are 2D fields named with suffix ‘xxxK’ where ‘xxx’ stands for the temperature value

• XISOTH : altitude of the isentropic levels
