How to run the MESO-NH model using operational ECMWF-IFS data (on model levels) as ICs & BCs

1. Download IFS data (on ecgate) as follows:

-bash-4.1$ cat STATIC.REQ
retrieve,
class   = od,
expver  = 1,
stream  = oper,
date    = 2020-11-15,
time    = 00,
area    = -10/-85.0/-50.0/-60.0,
step    = 0/to/6/by/6,
type    = fc,
levtype = sfc,
param   = 129.128/172.128,
grid    = 0.1/0.1,
target  = "STATIC_20201115-00.grib{edition}"

-bash-4.1$ cat SFC.REQ
retrieve,
class   = od,
expver  = 1,
stream  = oper,
date    = 2020-11-15,
time    = 00,
area    = -10/-85.0/-50.0/-60.0,
step    = 0/to/6/by/6,
type    = fc,
levtype = sfc,
param   = 39/40/41/42/139/141/170/183/236,
grid    = 0.1/0.1,
target  = "SFC_20201115-00.grib{edition}"

-bash-4.1$ cat ML1.REQ
retrieve,
class   = od,
expver  = 1,
stream  = oper,
date    = 2020-11-15,
time    = 00,
area    = -10/-85.0/-50.0/-60.0,
step    = 0/to/6/by/6,
type    = fc,
levtype = ml,
levelist= 1,
param   = 152,
grid    = 0.1/0.1,
target  = "ML1_20201115-00.grib{edition}"

-bash-4.1$ cat ML.REQ
retrieve,
class   = od,
expver  = 1,
stream  = oper,
date    = 2020-11-15,
time    = 00,
area    = -10/-85.0/-50.0/-60.0,
step    = 0/to/6/by/6,
type    = fc,
levtype = ml,
levelist= 1/to/137,
param   = 130/131/132/133,
grid    = 0.1/0.1,
target  = "ML_20201115-00.grib{edition}"

Note: change "date", "time", "area", "step", "target" as needed.

2. cat all the grib files (both edition=1 && edition=2) into one single file.

NOTE (very important!): the STATIC file has to be the first file in the cat command

-bash-4.1$ cat STATIC_20201115-00.grib1 SFC_20201115-00.grib1 ML1_20201115-00.grib2 ML_20201115-00.grib2 > ALL.grib

3. run the grib_filter command 

-bash-4.1$ grib_filter -v rule.filter ALL.grib

where rule.filter is:

write "fc_fglobal.[stepRange].grib";

4. Then follow the instructions below:
