Data Storage: Files are normally available on line for three months, after which they will be deleted from the website. Data is not archived by Pierce County prior to deletion and is therefore unrecoverable. Users are encouraged to download data as soon as possible. However, archived daily files may be available through the PANGA website at ftp://panga.cwu.edu/pub

File Naming:  The file naming convention is as follows: ssssdddh.yyt.gz.  Where “ssss” is used to identify the site name, “ddd” is the day of the year, “h” is the hour identifier (UT), “yy” is the year, “t” is the file type, and gz is the type of compression used. The files are organized in directories according to the year, day of year, site  and UT hour of day.

Do not be confused by the times listed on the left of the Rinex data page.  They are the times the files were posted from the sites.  The 8th character in the file name indicates the data range: "a" 0:00 UT - 0:59 UT , "b" 1:00 UT - 1:59 UT, ..., "x" 23:00 UT - 23:59 UT.
