Re: MC netcdf

[Christof Appenzeller <christof.appenzeller@xxxxxx>]

Hi,
Thanks to Kevin O'Brien and Steve I could solve the MC multi-netcdf file
problem. Two points were important (for sun solaris 7):

1) use ' ' and not ` ' (as given in the html manual)

2) use a space before $
 $FORMAT_RECORD
and not
$FORMAT_RECORD 

An other point is that the D_TIME_UNIT needs to be given in second. 

I attach the correct version of the descriptor file.

Happy ferreting
Christof
