The text file PET.txt contains hourly data from January 1, 1948, to September 30, 2015. This data is computed from average daily air temperature, average daily dewpoint temperature, daily unadjusted wind speed, and daily solar radiation using the Fortran program LXPET. This program is documented in detail in Murphy (2005).
