Dear Zeinab and all
Yes there was a failure in a netcdf function used to determine the
had-hoc date in the emission file. This bug is fixed now and the new
version will be released soon (10-15 days). For the
chemistry/aerosol optionm a couple of other issues are being fixed :
dust emission are now performing as version regcm4-1, there is even
an option to use an alternative dust emission size distribution (cf
Nabat et al, ACPD), and some additional diagnostics have been added
to the output. The sulfate aerosol showed also some problem this is
being fixed to perform as previous version.
For those who are wondering , those new bugs appearing in some in
the standard ( compared to standard 4.1 and 4.1-chem ) are coming
mainly from restructuring the code, externalizing the chemistry
module and work on the input outputs: they are not due to
modification of the parameterization themselves.
Note also that , for the gas-phase chemistry, we use now RCP
emission scenario which are different from the emission considered
in the reference papaer of Schallaby et al, GMD. Especially since
the emission Nox/voc ratios might be different, this can lead to
difference in ozone production ( which does not mean there is a bug
in the chemistry scheme) .
Ideally I would like to produce benchmark runs for every option of
the chemistry , with the associated namelist and put that on a web
page. Like this every user will be able to check that his version is
consistent.
All the best
Fabien

Dear
all
I
try to run the new version of regcm ( RegCM-4.3-rc12) with
chemistry, using chemsimtype = 'CBMZ'.
The
namelist is attached
After
attempts, the interpolation of the emissions occured and the
file of "
test_001_CHEMISS.nc " is created , but the run
stops in the beginning, and the error is :
READY ICCH DATA for 2001-08-01 00:00:00 UTC
SEARCH CHBC data for 2001080106
READY CHBC from 2001080100 to 2001080106
READ CHEM EMISSION for 2001080100
Opening ch. emission file input/test_001_CHEMISS.nc
Variable CO_flux read err
NetCDF: Index exceeds dimension bound
-------------- FATAL CALLED ---------------
Fatal in file: mod_che_ncio.F90 at line: 367
CHEM_EMISS FILE
-------------------------------------------
mod_che_ncio.F90 : 367: 1
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
rank 0 in job 4 localhost.localdomain_59170 caused

exit status of rank 0: return code 1
So, please can anyone help me
to run the chemistry in RegCM-4.3-rc12
Thanks in advance
Best regards
