“…To study the urban impact on LST, 16 images were used in obo-Dioulasso (Burkina Faso, Sub-Shaharan Africa) over 22 years (1991-2013) [83], 11 images in the semi-arid city Erbil, Iraq over 21 years (1992-2013) [84], and two images in Changchun, China over 12 years (1993-2005) [85]. Also, LST trend analysis was performed in urban areas (cities) in Ghana [86], India [87], Iran [88], Thailand [89], and the USA [90,91] using variable numbers of Landsat images in the study periods, i.e., three in six, eight (two in each year) in 30, four in 30, six in 10, and 53 in five years, respectively. Other studies performed LST trends in finding relationships with LULC-Land Use Land Cover changes [92,93], forest cover changes [94], and changes in NDVI-Normalized Difference Vegetation Index [95]- [97] and green roof [98].…”
