Landsat scenes ETMC and TM, and TERRA ASTER scene were used. The different spatial (60,90, 120 m) and/or radiometric (8,12 bits) resolutions anabled the accuracy of surface temperature. Removing forest buffer zones resulted in greater statistical significance (approximately by 25-40%). The optimal width of forest edge removed was determined to be 90 m. The resulting explained variability (R2) was 0.57, 0.52, 0.47 for ETMC , ASTER, and TM, respectively. The potential use of ST modeling is to identify temperature anomalies caused by different types of forest disturbance (e.g.harvesting, disease, insect attack) or changes in the condition of stands (e.g. water stress).
