The regional series use information from eight long station records, five over SMT, two for SIT and one for NIT. All three regions show long-term statistically significant seasonal warming over both 1861-2000 and 1901-2000, except for the winter season. For the calendar year, the temperature change explained by a linear trend over 1861-2000 is 0.69C, 0.64C and 0.77C for SMT, SIT and NIT, respectively.
