| Description: | DATA REPROCESSED and CORRECTED:
hese data were reprocessed to fix the problems described below.
One variable in an intermediate datastream (i.e. surfspecalb1mlawer.c0) to this VAP did
not have a missing_value attribute defined. Variables without a missing_value used
__FillValue as their missing value. The downstream VAP did not recognize those fill values as
"bad" and used them in its processing messing up the logic and resulting in no clear days
being found.
Inability to access the DQR database resulted in a gap in data files for
20140218-20140419.
The data were archived in August 2016. Please retrieve the reprocessed data for use in

--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------
An update to the shared libraries negatively impacted the Value Added Product (VAP)
because one variable in its intermediate datastream (i.e. surfspecalb1mlawer.c0) did not have a
missing_value attribute defined. An update to the transformation library made in the
spring was for variables without a missing_value to use __FillFalue as their missing value.
In a typically VAP the use of fill values instead of missing would be immediately caught
by processes that check the output files before shipping to the archive. However, this
fill value was in an intermediate datastream that is not shipped to the archive, and is
immediately removed after it is no longer needed. The downstream VAP did not recognize those
fill values as "bad" and used them in its processing messing up the logic and resulting
in no clear days being found. |
