Landsat 8 data is used for experimentation during 21st Jan 2018 and 6th Feb 2018 for LST analysis of identified area. More than half of the land area in the Mandya district is under agricultural use. Fluctuations in LST affects the quality of agricultural production. As a result, proper estimation of LST is very much required for the management of crop growth, development, and yield component. Spectral radiance from band 10 and emissivity of thermal infrared bands was used as input for LST estimation. Surface emissivity was obtained with the help of NDVI (Normalized Difference Vegetation Index), Leaf Area Index (LAI), and Albedo in the Mandya region. ERDAS IMAGINE and ArcGIS software were used for modeling. The obtained data compared with weather station data collected by KSNDMC (Karnataka State Natural Disaster Monitoring Centre). For this analysis, we considered two sets of data taken on different dates during the said period. The Root Mean Square Error (RMSE) and correlation coefficient are used as statistical criteria for evaluating the model efficiency. From the comparison, it is found that RMSE and R for the first date are 0.94\u00b0C, 0.62, and for the second date, it is 1.26\u00b0C, 0.88, respectively. It is observed that LST and weather data do follow the same pattern for the selected 12 meteorological stations.<\/p>\n\n\n\n<p><em>Keywords:\u00a0Emissivity; Land surface temperature (LST); NDVI; LAI; LANDSAT-8; Mandya<\/em><\/p>\n\n\n\n<div style=\"height:2rem\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-tkuwpbs5-bs5-div ref_ol\" data-aos=\"normal\">\n<ol>\n<li>[1] M Bisquert, J.
