Hello,

It seems like a bug. if so, I would appreciate it if unidata team
would fix the bug.

Tatsuya,

Not a bug...


the DataType=48  in the file is wrong, it can only be values 0,64,128,196:

BUFR Documentation:
Bit 1 = 1 observed data = 0 other data
Bit 2 = 1 compressed data = 0 non-compressed data
Bit 3 - 8 set to zero (reserved)

I even remove 3-8 bit values that resulted in DataType =0 but then
the descriptors were outside the range ie 0-48-50, in table 12 the
highest 0 descriptor is 0-35-

Contact the data provider for more information.



      if( dds.getDataType() == 192 || dds.getDataType() == 64 ) {
         isCompressed = true;
         compressed();
      } else if( dds.getDataType() == 128 || dds.getDataType() == 0 ) {
         isCompressed = false;
         uncompressed();
      } else {

         return false;

Robb...
