  Initial Request
----------------------------------------------------------------

I'm trying to convert the Bufr data into netcdf for the point_stat tool, however, I encountered the following error:

/scratch3/BMC/wrf-chem/KaYee/met/obs

Kayee.Wong at tfe02 obs]$ pb2nc testing/pmfine_081018_Peak.obs pmfine_081018_Peak.nc PB2NCConfig

Is the Bufr data I got is not compatible to the pb2nc tool?

KaYee,

I moved the question you asked me over to the met-help queue.

I logged on to theia and took a look at the data you're trying to
process.  You're attempting to run this file through pb2nc you're
getting no observations.  This does not appear to be a BUFR file.  It
looks like it's ASCII.  I ran head -10 to see the first 10 lines:

[John.H.Gotway at tfe01 testing]$ head -10 /scratch3/BMC/wrf-
chem/KaYee/met/obs/testing/pmfine_081018_Peak.obs
BEGIN_FILE
!
! PM2.5 Data
!
FORMAT_VERSION,    2
AGENCY,            DMC
FILENAME,          pmfine_081018_Peak.obs
DATA_VERSION,      201808111442
TZONE,             EDT,4
QC_LEVEL,          1 Set by Program QC

Binary BUFR data files start with "BUFR" as the first 4 characters,
which are definitely not present here.

I'd suggest doing some more digging to determine exactly how this data
is formatted.

Thanks,
John
