Dear colleagues,

   We are in the process of transitioning to a new server here at the
CDDIS.  We are also modifying the main directory structure of our archive.
The new server, cddis.gsfc.nasa.gov, is now available for anonymous ftp 
access to review this structure.  All data and products are under 
directories by datatype; some examples:

/gps/data/daily     30-second GPS daily files by year and DOY
         /highrate  1-second GPS 15-minute files by year and DOY
         /hourly    30-second hourly data by year and DOY
         /satellite GPS data from on-board receivers by satellite, year and DOY
    /products (unchanged from cddisa)
/doris (unchanged from cddisa)
/slr/data/npt      on-site normal point data by satellite, year and DOY
         /fr       full-rate data by satellite, year and DOY
    /products
/vlbi (unchanged from cddisa)

The structure not only simplifies our archive but organizes the data
in a more logical format.  We have conducted tests with selected data
suppliers; once we have tested our software we will be contacting the
rest of our suppliers about the transition to our new system.  Once 
our new system is operational, we will be offering a transition period 
where both cddis and cddisa will be maintained, thus allowing users to 
transition their s/w to our new archive structure.  

   At this time I would like your opinion on the new structure.  Please
send me any comments you have on this new structure.

Thanks and best regards,
Carey.
