when i do the ./Bin/chenm_icbc test.in, there is a error and the message as follow:

GLOBIDATE1 : 2002-03-01 00:00:00 UTC

 GLOBIDATE2 : 2002-03-02 00:00:00 UTC

 NSTEPS     :             5

 NetCDF: Unknown file format

 mod_ae_icbc.F90 :       92:Error open aeid file:           -51

Is the netcdf in my system too old? so i want to know the version of netcdf that be used to write aerosol data.

thank you !!!
