Seasonal and Annual Mean Temperatures for Armagh Observatory from the mean of three independent series: (1) Max and Min from 1844, (2) twice-daily readings of the dry bulb of the hygrometer 1844-1965 and (3) twice daily "spot" temperatures 1796-1882. The twice daily "spot" series has been patched with Dunsink and Phoenix Park data in the interval 1825-1833. No shifts have been applied to the three sets of data to link them together. See paper by Butler et al. 2005, Int. J. Climatol. 25, 1055-1079 for details of coverage and calibration. Column (1) Year, (2) Winter (DJF), (3) Spring (MAM), (4) Summer (JJA), (5) Autumn (SON), (6) Annual (J-D). Note the annual J-D mean will not be the same as the mean of the four seasons. 1796 6.50 6.86 12.20 7.54 7.69 1797 3.51 6.71 14.31 8.79 8.62 1798 3.98 8.02 14.19 7.93 8.41 1799 2.57 5.38 12.73 8.05
