# This program expects data stored in the file; the data comes from this
 +
# URL: http://www.metoffice.gov.uk/climate/uk/stationdata/
 +
# where temperatures in the UK have been recorded over the past 200 years or so.
 +
# The format for each line is the following:
 +
# year
 +
# month of the year (1 for January, 2 for February, etc.)
 +
# max temperature that month (in Celcius)
 +
# min temperature that month
 +
# number of days of air-frost
 +
# amount of rain (millimeter)
 +
# number of sun hours that month
 +
#
 +
# The original data files can be found on this site. The following legend appears on all the data files:
 +
# Estimated data is marked with a * after the value. Missing data (more than 2 days missing in month)
 +
#  is marked by ---. Sunshine data taken from an automatic Kipp & Zonen sensor marked with a #,
