About These Data
The acronym CLASS refers to an atmospheric balloon sounding
system developed by NCAR's Surface and Sounding Systems Facility
(SSSF). Balloon positioning relies upon Cross-chain LORAN
navigation, giving highly accurate differential "fixes", and
therefore, accurate winds. This Cross-chain LORAN Atmospheric
Sounding System (CLASS) has been in use by NSF researchers since
1986.
Tapes and Time Periods Available
The following tapes for the indicated projects are available. All
data are packaged in UNIX "tar" files on 8-mm tape, or may be
made available for ftp as compressed UNIX tar files. Individual data
files within the tar sets are simple ASCII files. Tape information
files should be consulted to determine if specific data actually exist
(click on the tape number to view the summary file;
