Subject:
SGP/SURFSPECALB/C1 - Value Added Product error
DataStreams:sgpsurfspecalb1mlawerC1.s1, sgpsurfspecalb1mlawerC1.c1
Description:
The configuration files needed to perform the transformations correctly were not released 
with the updated software. As a result the data is not as accurate as it could be because 
the alignment of the averaged data was assumed to be center of the averaging bin, but 
some instances exist where the averaging alignment was not at the center of the bin.  This 
data product averages the input over a five minute period, and then an additional 
transformation is applied to a longer time interval later in the process. The impact on this 
data is minor and expected to be under the uncertainty associated with the methods applied.  
This processing difference should not affect the use of the data.
Suggestions: 
null
