Abstract

ABSTRACT: Land surface temperature (LST) depends primarily on the land surface material and climatic conditions. The present study focuses on deriving the LST of Raipur City and generating the relationship between LST and some land surface indices, like NDVI, NDWI, NDBI, NMDI, and NDBaI for better land-use planning and environmental management inside the city. These land surface indices respond in different ways with the changes of LST in an urban landscape. There are only a few numbers of research works available on the relationship of LST and land surface indices in a tropical city for pre-monsoon season. The present study has been performed on a total of fifteen multi-date Landsat data sets of the pre-monsoon season from 2002, 2006, 2010, 2014, and 2018. The mono-window algorithm has been applied in retrieving the LST. Results show that LST builds a positive relation with NDBI, NDBaI, and NDWI and a negative relation with NDVI and NMDI. These relationships are stronger in the area below mean LST (low LST zones) and weaker in the area above mean LST (high LST zones). It indicates that the values of LST are largely influenced by the different land surfaces, like vegetation, water, soil, and built-up area.
