Optional CARDs 2C, 2C1, 2C2, 2C2X, 2C3
Only one of IHA1, ICLD1 or IVUL1 is allowed:
IHA1
Aerosol model extinction and meteorological range control for the altitude, ZM. See
IHAZE (CARD 2) for options.
ICLD1
Cloud extinction control for the altitude, ZM; see ICLD (CARD 2) for options.
When using ICLD1 it is necessary to set ICLD to the same value as the initial input
of ICLD1.
IVUL1
Stratospheric aerosol profile and extinction control for the altitude ZM; see IVULCN
(CARD 2) for options.
The precedent order of these parameters (IHA1, ICLD1 and IVUL1) is as follows:
If (IHA1 > 0) then others ignored
If (IHA1 = 0) and (ICLD1 > 0) then use ICLD1
If (IHA1 = 0) and (ICLD1 = 0) then use IVUL1
If AHAZE and EQLWCZ are both zero, the default profile is loaded from IHA1, ICLD1,
IVUL1.
ISEA1
Aerosol season control for the altitude, ZM, see ISEASN (CARD 2) for options.
ICHR
Used to indicate a boundary change between 2 or more adjacent user defined aerosol
or cloud regions at altitude ZM (required for IHAZE = 7 or ICLD = 11).
ICHR
= 0 no boundary change in user defined aerosol or cloud regions (regions are not
adjacent).
= 1 signifies the boundary change in adjacent user defined aerosol or cloud
regions.
NOTE: ICHR internally defaults to 0 if (IHA1 ≠ 7) or (ICLD1 ≠ 11).
