Several logicals and integer must be set to .true. in callphys.def if not, default values are .false.

callphys.def

FLAGS/PARAMETERS	COMMENTS
co2clouds=.true.	Call the subroutine
co2useh2o=.true.	Allow the use of water ice particles as CCN for CO2
meteo_flux=.true.	Supply meteoritic particles
CLFvaryingCO2=.true.	Allows a subgrid temperature distribution of amplitude spantCO2 (=integer in callphys.def, typically 3)
satindexco2=.true.	Allows the filtering out of the sub-grid T distribution if the GW saturates in the column. Based on Spiga et al. (2012)
	.true.: an index is computed for the column and the sub-grid T distribution is applied if the index remains < 0.1
	.false.: applies the sub-grid T everywhere default value is .true., only applies if CLFvaryingCO2=.true. anyway.
imicroco2=50

traceur.def

add these two tracers: ccnco2_number, ccnco2_mass
