This study investigates the relationship between land surface temperature (LST) and urban indices (such as: Normalized Difference Bareness Index (NDBaI), Normalized Difference Buildup Index (NDBI) and Urban Index (UI)) using Landsat-8 OLI imagery, for Iasi municipality area. Landsat data were used to estimate the LST, NDBI, NDBaI and UI for Iasi municipality area, between 2013-2016. In that period, the mean temperature rose by about 2C, so as to 2016 the mean temperature was of over 30C and the maximum temperature exceeded 40C. Analyzing the relationship between LST and urban indices it can be noticed that, whilst NDBI and UI indices have high a correlation with LST, the correlation between NDBaI and LST is lower. The R fluctuates significantly from over 0.4 for NDBI and UI to about zero for NDBaI. Therefore, NDBI and UI are accurate indicators of SUHI effects, as against NDBaI and can be used as a complementary metric to the traditionally applied NDVI for analyzing surface urban heat island studies.
