SATELLITE BASED LAND SURFACE TEMPERATURES ALONG THE COASTAL MANDALS OF VISAKHAPATNAM DISTRICT, ANDHRA PRADESH, INDIA

The Rapid development of any city leads to Changes in Land use Land cover pattern, these changes attribute to Changes in Land Surface Temperature (LST). The LST from Earth Observation satellites is essential factor in global climate change, vegetation growth and also in monitoring urban climate, understanding the environmental conditions necessary to sustain human life.The Present Study is carried out to derive the LST of Coastal Mandals of Visakhapatnam District, A.P. India by using Landsat 8 Optical Land Imager (OLI) of 30 m resolution and Thermal Infrared Sensors (TIR) data of 100 m resolution. The Spectral radiance was estimated using TIR band 10. Emissivity was derived with the help of NDVI. From the detailed analysis, identified that, the LST of the present study area is varying from 24.12 o C to 37.74 o C during the month of May 2016.
