MC netcdf

[Christof Appenzeller <christof.appenzeller@xxxxxx>]

Hi all,

I have a question/problem about constructing a multi-netcdf file. I have
a number of NCEP Reanalysis netcdf files. Like air.sig995.1991.nc,
air.sig995.1991.nc etc.
Each file contains daily data for one year (365 or 366 day). Time units
are hours. 

currently SET data sets:
    1> ./air.sig995.1991.nc  (default)
 name     title                             I         J        
K         L
 AIR      mean Daily Air temperature       1:144     1:73      ...      
1:365

I linked the files to air.sig995.1991.nc.001, air.sig995.1991.nc.002 etc
I used the manual V5.22 to construct the following descriptor file
(name: all.air.2.des).

*********************************************************************
$FORMAT_RECORD
      D_TYPE               = `  MC',
 $END

 $BACKGROUND_RECORD
      D_TITLE              = `Air Temperature NCEP Reanalysis',
      D_T0TIME             = `01-JAN-0001 00:00:00',
      D_TIME_UNIT          =  24.0,
      D_TIME_MODULO        = .FALSE.,
 $END

 $MESSAGE_RECORD
 $END

 $EXTRA_RECORD
 $END

 $STEPFILE_RECORD
      s_filename           = `air.sig995.1991.nc.001',
      S_AUX_SET_NUM        = 0,
      S_START              = 17444016.,
      S_END                = 17452752.,
      S_DELTA              = 24.0,
      S_NUM_OF_FILES       = 1,
      S_REGVARFLAG         = ` `,
 $END
 $STEPFILE_RECORD
      s_filename           = `air.sig995.1991.nc.002',
      S_AUX_SET_NUM        = 0,
      S_START              = 17452776.,
      S_END                = 17461536.,
      S_DELTA              = 24.0,
      S_NUM_OF_FILES       = 1,
      S_REGVARFLAG         = ` `,
 $END
 $STEPFILE_RECORD
      s_filename           = `**END OF STEPFILES**'
 $END
*********************************************************

Then I typed in ferret (running on a sun workstation)

set data_set all.air.2.des

And got the following error:

 **TMAP ERR: Error in namelist record
             Error in: FORMAT_RECORD; or file not descriptor file
             Data set: ./all.air.2.des


Obviously I do something wrong. Any help?

Thanks! Christof
