Land Surface Temperature (LST) is a crucial urban and regional meteorological component
that affects how the ground surface interacts with the atmosphere. LST is considered a
significant parameter in many scientific research studies, including global climate change
studies, agricultural processes, and various biogeochemical cycles. The dynamics of LST and
Land Use Land Cover (LULC), are important markers of forest fragmentation,
industrialization, and urbanization. Unplanned urbanization results in LULC pattern alterations
on a broad scale, which results in ecosystem damage and has a negative impact on public health,
particularly in developing nations. In this work, we used Landsat 5 and 8 imageries to analyze
the LST variations in Hyderabad from 1990 to 2020. The specific objectives of this study were
to compute the change in LULC and LST during the study period and to establish the
relationship between land surface temperature and urban settlements.
