NAM_DIAG - Chemistry

Only available if LUSECHEM=T in YINIFILE.des

• add LCHEMDIAG=T in NAM_DIAG to store following variables :

Name	Meaning [Unit]	Dimension
O3 …	Chemical scalar variables as defined in BASIC.f90 (ppb)	3D

Note

Following options can be used in NAM_DIAG when LCHEMDIAG is activated :

Fortran name	Fortran type	Default value
XCHEMLAT	REAL	XUNDEF
XCHEMLON	REAL	XUNDEF
CSPEC_DIAG	CHARACTER(LEN=1024)
CSPEC_BU_DIAG	CHARACTER(LEN=1024)

• write chemicals species on vertical profile defined by (XCHEMLAT,XCHEMLON)

• CSPEC_DIAG : list of the chemical species for production/loss terms computation. Each species is separated by a comma. Ex : CSPEC_DIAG=’O3,CO,BIO’

• CSPEC_BU_DIAG : list of the chemical species for production/loss terms computation in all the reactions where the species is involved. Each species is separated by a comma. Ex : CSPEC_BU_DIAG=’O3,CO,BIO’
