SGP/MERGESONDE/C1 - Reprocessing Notice (RID 927)

See below for details of reprocessing that was completed on 20140904.  Original DQR 
category: 4 (Red, Incorrect).

-----------------------------------------------------------

All precip values are incorrectly reported during the period:  

From 20060101-20101231 all precip values are incorrectly reported as missing, or -9999.  

From 20110101-present all precip values are reported as 0 even though the qc_precip 
variable flags the data as missing, or -9999. 

The precipitation data from the co-located surface met station were not actually missing, 
but the MERGESONDE VAP did not properly ingest these data.  While the 0 precip values 
reported after 20110101 in MERGESONDE may be correct on days with no precip, they are not 
actually tied to the measurements from the co-located rain gauge and are due to a VAP 
software error.

To correct this issue, the MERGESONDE software will need to be corrected so the data can 
be reprocessed.  Because precip is a secondary variable in MERGESONDE, this issue is 
considered low priority and the VAP will not be reprocessed until a sufficient number of 
issues in the VAP have been identified.

SGP/RLPROF/C1 - Reprocessed and Corrected: Incorrect units

DATA REPROCESSED and CORRECTED: 

The units for water vapor mixing-ratio related variables in the rlprofbe1news VAP were 
incorrectly reported as g/km instead of g/kg. The netcdf files were modified and the data 
were reprocessed to address incorrect units issue. 

ORIGINAL DQR CATEGORY: Transparent(Does not affect quality)
