README file for app_temp_thr.dat

This file contains threshold values of temperature and apparent temperature
used to define extremes.

For each station, 3-hourly July and August data for 1961-1990 were used to
determine the 85th percentile values of daily average, daily minimum, and 
daily maximum ambient temperature and apparent temperature.
