This directory contains daily record maximum and minimum temperature data from
200 U.S. Historical Climatology Network stations meeting stringent data completeness
requirements. The directories are as follows:

/htxctxwtnctn contains individual station files for hot/cool Tmax records and
warm/cold Tmin records, giving the record value for the day of year
and the year(s) in which the record was set. There is also a 'ALL200sta' file
for each temperature record type that is a concatenation of all the station files,
sorted by station number.

/htxctx contains files for hot/cool Tmax records, where each line in a file gives the hot Tmax
and cool Tmax record value for each day of the year, along with the year the record was set or tied. 
There is also a 'ALL200sta' file that is a concatenation of all the station files,
sorted by station number.

/wtnctn contains files for warm/cold Tmin records, where each line in a file gives the warm Tmin
and cold Tmin record value for each day of the year, along with the year the record was set or tied.
There is also a 'ALL200sta' file that is a concatenation of all the station files,
sorted by station number.

/tmax_serial and /tmin_serial contain individual Tmax/Tmin station files, each sorted
from Jan. 1, 1911 through Dec. 31, 2010. There is also a 'ALL200sta' file that is a 
concatenation of all the station files, sorted by station number.

/tmax_by_doy and /tmin_by_doy contain individual Tmax/Tmin station files, each sorted
by day of year, i.e., all day 1's, all day 2's, etc. over 1911-2010. Data for each day
of the year is sorted from high to low for Tmax, and from low to high for Tmin.
There is also a 'ALL200sta' file that is a concatenation of all the station files, 
sorted by station number.

Also, an inventory file containing metadata for the 200 stations is available in this
directory (invent_200.txt).  A description of the inventory file's contents may be found
on the USHCN website at http://cdiac.ornl.gov/epubs/ndp/ushcn/daily_doc.html#stations
