Hi,

I want to read some BUFR files. I selected netcdf-java for this task, since 
your library is still maintained and it seems to have a very good documentation.

While implementing my reader-class these questions occurred:

1. I examined my files with toolsUI-4.6.10.jar and noticed that all data is 
stored under a structure named "obs". What is "obs"?

2. Besides some variables, which are very easy to read, I also have a bunch of 
data, which is stored in a Sequence. Your example to read this data works very 
well, but I'm not able to read Sequences using a NetcdfDataset. Is there an 
example available for this?

3. I know that some values contains a missing. This missing can be detected 
with your isMissing(value) function:
VariableDS valueRaw = (VariableDS)dataset.findVariable("obs." + name);
Boolean dataIsMissing = valueRaw.isMissing(???);
What should I set for ??? in the above example? I want to know whether or not 
valueRaw is missing.

Thanks

Kind regards

Annabelle
