Hello, Alicec. i can complie the era52arl program, but when i use the bash belowI'm not sure I understand the trouble you are having with downloading the files. How are you trying to download them?
Are you using the python code or other way? Can you describe this problem in more detail?
The reason you are getting the error from era52arl is that you need to input at least 2 grib files - one
for the surface fields and one form the pressure level fields. The default name for the pressure level fields
is DATA.GRIB. The default name for the surface fields is SFC.GRIB. You can specify other names for these with the -i and -a options (see below).
The error you are getting is because it is not finding the SFC.GRIB file.
After it says Allocating igrib, you should also get a message that says Allocating agrib.
a default era52arl.cfg will be created if none exists or
alternate name is not specified with the -d option.
This file specifies variables and pressure levels to be written.
-d[decoding configuration file {name | create era52arl.cfg}]
-i[input grib1 file with pressure level fields name {DATA.GRIB}]
-a[input grib1 analysis surface fields name {SFC.GRIB}]
-f[input grib1 forecast surface fields name {SFC2.GRIB}]
-o[output data file name {DATA.ARL}]
-v[verbose mode {False}]
./era52arl_debug -i pressure_level.grib -a surface_level.grib -o output.arl
i face the problem, the fault is below
(eccodes_build) [@localhost era52arl]$ ./era52arl_debug -o output.arl
