Subject:	NSA/CPC/X1 - Global metadata error
DataStreams:	nsaaoscpcX1.a1
Description:	The global metadata in the nsaaoscpcX1.a1 file incorrectly specifies the CPC model number as "3372". The correct model number is "3010". This is a metadata error only. The data are not affected. A low priority reprocessing task has been submitted.
Measurements:	nsaaoscpcX1.a1: base_time

Subject:	NSA/CPC/X1 - Reprocess: reprocessing from raw data in preparation for not-yet-released b1 level
DataStreams:	nsaaoscpcX1.a1
Description:	End to end reprocessing to generate new a1 datastreams is needed so that when the harmonization software is released to production, we will be ready with the a1 datastreams that are input to the subsequent processing software.
