From 1979 until 2004 the University of Wisconsin Space Science and Engineering Center (UW-SSEC) archived GOES satellite data for the official National Satellite Archive which now resides at the National Climatic Data Center, in Asheville, North Carolina. The original operational GOES satellite archive was recorded at UW-SSEC on Sony U-matic tapes starting in 1978 and continued until 1997. It became apparent that the original tapes were slowly deteriorating, so in 1999 a project to rescue the data from U-matic tape and transfer the data to IBM 3590 tape media was begun. This rescue was completed in 2005. During the rescue project all data from 1978 through 1996 was recovered and saved to 3590 media. At the time of the rescue, no software existed to reconcile the redundant data and interrogate the anomalies that were found. The process of reconciling ingest and decode anomalies was initiated in 2009. The interrogation and reconciliation process for data from SMS-1, SMS-2 and GOES-1 through GOES-7 is now nearing completion. The process and methods used to reconcile the data are discussed.
