problem with opening multiple NetCDF files

[Karin Meier-Fleischer]

Hi Pavel,

first, you should delete the ZDEF line. For the variables it should not
be a one it must be a zero:

DSET ^%y4-%m2.nc
OPTIONS template
TITLE Variables
UNDEF -999
XDEF longitude 360 linear -179.500000 1.00000
YDEF latitude 181  linear -89.5000000 1.000000
TDEF ftime 12 linear 01apr2000  1mo
vars 8
aot       0 t,y,x
aot_land  0 t,y,x
aot_water 0 t,y,x
aot_dust  0 t,y,x
angst     0 t,y,x
small     0 t,y,x
medium    0 t,y,x
large     0 t,y,x
endvars

Hope this helps.

Ciao, Karin
