Land Surface Temperature (LST) is an important aspect in global to regional, change studies, for control of climate change and balancing of high temperature. Urbanization is one of the influencing factors increasing land surface and atmospheric temperature, by the emission of greenhouse gases (e.g., CO 2 , NO, methane). In the present study, LST was derived from Landsat-8 of multi temporal datasets to analyse the spatial structure of the urban thermal environment in relation to the urban surface characteristics and land use land cover (LULC). LST is influenced by the greenhouse gases i.e., CO 2 plays an important role in increasing the earth's surface temperature. In order to provide the evidence of influence of CO 2 on LST, the relationship between LST, air temperature and CO 2 was analysed. Landsat-8 satellite has two thermal bands 10 and 11. These bands were used to accurately calculate the temperature over the study area. Results showed that strength of correlation between ground monitoring data and satellite data was high. Based on correlation values of each month April (R 2 =0.994), May (R 2 =0.297) and June (R 2 =0.934), observed results show that Band10 was significantly correlating with air temperature. Relationship between LST and CO 2 levels were obtained from linear regression analysis. Band 11 was correlating significantly with CO 2 values in each of the months April (R 2 =0.217), May (R 2 =0.914) and June, (R 2 =0.934), because band11 is closer to the 15 micron band of CO 2 . From the results it was observed that band 10 can be used for calculating air temperature and band11 can be used for estimation of greenhouse gases.
