Reading Landsaf/LSA SAF HDF5 data

Dear readers,

I am currently having some problems trying to handle Landsaf HDF5 files with NCL. I can't even open or read the data using NCL.

NCL version: 6.0.0

system: x86_64 GNU/Linux

I put an example-file on your ftp server:

/incoming/HDF5_LSASAF_MSG_DIDSSF_Euro_201212050000.bz2

after unzipping:

/incoming/HDF5_LSASAF_MSG_DIDSSF_Euro_201212050000

(I have noticed, that NCL needs the proper file extension - you can simply add .h5, but it doesn't solve the problem).

I have tried a few very simple commands, like ncl_filedump or addfile:

>ncl_filedump HDF5_LSASAF_MSG_DIDSSF_Euro_201212050000.h5

>file = addfile("HDF5_LSASAF_MSG_DIDSSF_Euro_201212050000.h5","r")

The following error occurs:

fatal:An internal error has occurred. The file format requested does not appear to be supported, could not open (HDF5_LSASAF_MSG_DIDSSF_Euro_201212050000.h5)

Now my question is: Are there different types of HDF5 files (when it comes to file structuring) and could it be, that the ones from Landsaf cannot be read by NCL? Otherwise I could use some hints how to read them properly.

Best regards,

Frank
