These files comprise CDIAC's most current version of USHCN Vs. 2.5 monthly data
Note: Previously available data files extending only through 2012 have been
copied to the /through_2012 directory. Users may find that differences exist
in the pre-2013 data between those files and the files updated through 2013,
due to NCDC adjustment algorithms. The /through_2012 directory will not be
maintained long term, but is offered as a convenience for users who may be
in the midst of work using those files.
Data files have been compressed using the "gzip"
command (use "gunzip" to uncompress on unix-based systems).
Windows and other Operating System users are encouraged to consult
http://www.gzip.org/ for information regarding uncompressing GZIP files.
Please see the "Executables" and "Frequently Asked Questions" sections for
information about your particular operating system.
The data are also available via a graphical user interface (GUI)
