[RegCNET] بخصوص: run chemistry in RegCM-4.3-rc12

[Zeinab Salah]

Dear Fabien 
Thank you for your concern. I installed the last version, RegCM-4.3-rc14 (using pgf90 and  netcdf 4.1.3 ).
the steps of creation and interpolation of emissions are completed, but the run stops in the beginning  after openning output files without error message, as in the attached file  "error.txt". So what is the error in this run?

Thanks in advance
Best regards

Zeinab Salah

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
