NSA/SURFSPECALB/C1 - Reprocessed and Corrected: Value Added Product error |
| Affected Datastreams: |
nsasurfspecalb1mlawerC1.s1 |
| Description |
DATA REPROCESSED and CORRECTED:
These data were reprocessed to fix the minor problem caused by the configuration.
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.
The data were archived in August 2016. Please retrieve the reprocessed data for use in your analysis.
