dc.description.abstract	The main objective of this paper is to find some concrete evidence of changing pattern of air temperature in Sri Lanka using secondary data available in different government and non-government organizations. The daily air temperature data (during the period 1961-2001) collected from the Meteorological Department and daily surface temperature data (during the period 1881-1981) collected from the NASA web site are the main data sources. 2 In addition to the GIS techniques such as surface interpolation, summarized by zones and geo-statistics, Regression and Time-series Analysis were used to achieve the set objectives. The study identified that the average temperature has increased in some areas such as Nuwara-Eliya, Anuradhapura, Colombo, Maha-Illuppallama, Hambanthota and Angunukolapalassa in Sri Lanka whilst some observatories depicted a declining trend of temperature and the area under high temperature is expanding.	en_US
