[Wrf-users] The format of radar data for wrfda

[brick]

Hi All

I'm learning how to assimilate radar data in wrf 3dvar. There are
some confusion about the format defined by the official tutorial.
1) Is "elv" give the altitude of radar station? But some levels' "elv" are
lower than radar in the example.
2) How to set "qc" (I think it mean quality control mark). Is there a table
defining it?

The format and example from official tutorial is attached below.

TOTAL RADAR (14X, I3) – FMT = (A14,I3)
#---------------------------------------------------------------------------------------------------------------
Head record for specific Radar information (site, lat0, lon0, elv, date, #
of data locations, max_levs)
 – FMT = (A5,2X,A12,2(F8.3,2X),F8.1,2X,A19,2I6)
#----------------------------------------------------------------------------------------------------------------
Head record for the specific location (FM-128 RADAR, date, lat, lon, elv,
levs)
 -- FMT=(A12,3X,A19,2X,2(F12.3,2X),F8.1,2X,I6)
Data-level record (height<m>, Radial_V<m/s>, qc, err, Reflectivity<dbz>,
qc, err)
Data-level record (height<m>, Radial_V<m/s>, qc, err, Reflectivity<dbz>,
qc, err)
………………………………………………………………………………………
  – FMT=(3X,F12.1,2(F12.3,I4,F12.3,2X))



TOTAL NUMBER =  1
