Fw: [ferret_users] How to combine data into one time axis?

[Jian Ma <jianma@xxxxxxxxxx>]

Hi Peter and All,

 

When I am using the following des for my Windows XP Ferret 5.51, an error appears:

 

 **TMAP ERR: Error in namelist record
             Didn't find: FORMAT_RECORD; or file not descriptor file
             Data set: .\QuikScat.des

 

Why?

Jian

 

$FORMAT_RECORD
D_TYPE = ' MC',
D_FORMAT = ' 1A',
D_SOURCE_CLASS = 'Satellite',
$END

 

$BACKGROUND_RECORD
D_TITLE = 'QuikScat Climatology 2000/01 - 2006/12',
D_T0TIME = '01-JAN 18:10:00',
D_TIME_UNIT = 2592000.0,
D_CALTYPE = '360_DAY',
$END

 

$STEPFILE_RECORD
s_filename = 'JFM.nc',
S_START = 1.0,
S_END = 3.0,
S_DELTA = 1.0,
$END

 

$STEPFILE_RECORD
s_filename = 'AMJ.nc',
S_START = 4.0,
S_END = 6.0,
S_DELTA = 1.0,
$END

 

$STEPFILE_RECORD
s_filename = 'JAS.nc',
S_START = 7.0,
S_END = 9.0,
S_DELTA = 1.0,
$END

 

$STEPFILE_RECORD
s_filename = 'OND.nc',
S_START = 10.0,
S_END = 12.0,
S_DELTA = 1.0,
$END

This is peter

You don't need to combine them. You just need to make a descriptor file like "Filename.des"  and read it. But, they have to be on the continuous time axis. 

You can refer to Ch10 Sec.4. of the ferret user guide or search for "descriptor" on The FAQ section.

Good luck

Dear Ferreters,

 

I have four data sets with monthly climatological winds of different seasons, as shown below. Now I need to save them in a new file with all 12 months in ONE variable.

 

Does anyone have an idea? Thank you very much!

 

     currently SET data sets:
    1> .\AMJ.nc
 name     title                             I         J         K         L
 TIME_BNDS
                                           1:2       ...       ...       1:3
 U        u wind component m/s             1:600     1:280     ...       1:3
 V        v wind component m/s             1:600     1:280     ...       1:3

 

    2> .\JAS.nc
 name     title                             I         J         K         L
 TIME_BNDS
                                           1:2       ...       ...       1:3
 U        u wind component m/s             1:600     1:280     ...       1:3
 V        v wind component m/s             1:600     1:280     ...       1:3

 

    3> .\JFM.nc
 name     title                             I         J         K         L
 TIME_BNDS
                                           1:2       ...       ...       1:3
 U        u wind component m/s             1:600     1:280     ...       1:3
 V        v wind component m/s             1:600     1:280     ...       1:3

 

    4> .\OND.nc  (default)
 name     title                             I         J         K         L
 TIME_BNDS
                                           1:2       ...       ...       1:3
 U        u wind component m/s             1:600     1:280     ...       1:3
 V        v wind component m/s             1:600     1:280     ...       1:3

Cheers,

Jian
