17/07/2012 == JL for LK

  • Generalization of aerosol scheme:
    • any number of aerosols can be used and id numbers are determined consistently by the code. Aerosol order not important anymore.
    • addition of a module with the id numbers for aerosols (aerosol_mod.F90).
    • initialization of aerosols id numbers in iniaerosol.F90
    • compile with -s x where x *must* be equal to the number of aerosols turned on in callphys.def (either by a flag or by dusttau>0 for dust). => may have to erase object files when compiling with s option for the first time.
  • For no aerosols, run with aeroco2=.true. and aerofixco2=.true (the default distribution for fixed co2

aerosols is 1.e-9; can be changed in aeropacity).

  • If starting from an old start file, recreate start file with the q=0 option in newstart.e.
  • update callphys.def with aeroXXX and aerofixXXX options (only XXX=co2,h2o supported for

now). Dust is activated by setting dusttau>0. See the early mars case in deftank.

  • To add other aerosols, see Laura Kerber.

10!
11!     RADINC.H
12!
13!     Includes for the radiation code; RADIATION LAYERS, LEVELS,
14!     number of spectral intervals. . .
15!
16!======================================================================
17
18!     RADIATION parameters
19
20!     In radiation code, layer 1 corresponds to the stratosphere.  Level
21!     1 is the top of the stratosphere.  The dummy layer is at the same
22!     temperature as the (vertically isothermal) stratosphere, and
23!     any time it is explicitly needed, the appropriate quantities will
24!     be dealt with (aka "top". . .)
25
26!     L_NLEVRAD corresponds to the surface - i.e., the GCM Level that
27!     is at the surface.  PLEV(L_NLEVRAD) = P(J,I)+PTROP,
28!     PLEV(2) = PTROP, PLEV(1) = ptop
29
30!     L_NLAYRAD is the number of radiation code layers
31!     L_NLEVRAD is the number of radiation code levels.  Level N is the
32!               top of layer N.
33!
34!     L_NSPECTI is the number of IR spectral intervals
35!     L_NSPECTV is the number of Visual(or Solar) spectral intervals
36!     L_NGAUSS  is the number of Gauss points for K-coefficients
37!               GAUSS POINT 17 (aka the last one) is the special case
38!
39!     L_NPREF   is the number of reference pressures that the
40!               k-coefficients are calculated on
41!     L_PINT    is the number of Lagrange interpolated reference
42!               pressures for the gas k-coefficients - now for a
43!               smaller p-grid than before
44!     L_NTREF   is the number of reference temperatures for the
45!               k-coefficients
46!     L_TAUMAX  is the largest optical depth - larger ones are set
47!               to this value
48!
49!     L_REFVAR  The number of different mixing ratio values for
50!               the k-coefficients. Variable component of the mixture
51!               can in princple be anything: currently it's H2O.
52!
53!     NAERKIND  The number of radiatively active species
54!               (set in scatterers.h ; built when compiling with makegcm -s #)
55!     NSIZEMAX  The maximum number of aerosol particle sizes
56!
