[Rabah Hachelaf]

Hello,

Why we can not concatenate or joint GFS 0.25 grib2 file
like in this example ?!
Any suggestions to solve this issue ?

Thank you
Rabah



grib_files = systemfunc("ls "+gfs_dir+"/gfs*") + ".grib2"
a = addfiles(grib_files,"r")

ListSetType (a, "join") or ListSetType (a, "cat")
rain =a[:]->APCP_P8_L1_GLL0_acc
