Study of climate variability of sargodha, Pakistan using satellite derived temporal land surface temperature and its comparison with ground data

Sargodha city has a weather of utmost temperature in the summers and calm cold in the winters. Comparative study of Sargodha ground temperature which is the part M. Phil research was initiated by using thermal infrared (TIR), near infrared (VNIR), and detectable bands of Landsat metaphors with ground based instruments being measured by Pakistan Meteorological Department (PMD) to ascertain the variation of results. The validation of remote sensing data was found with in ±5oC.The study was conducted to contribute to enhance the scientific evidence about rising of global temperature and increase of deforestation by materialistic inspection. The Landsat data for the month of October of years 2000, 2005, 2011 and 2015 was used and compared with ground station data. The results of the study show that the temperature of the land surface increased gradually from30°C in 2000, to 33°C in 2005 and34°C in 2011, but there was irregular decrease of temperature found in 2015 for the reasons required to be further investigated. The increase of temperature is attributed to the reduction of agricultural land and increase of developed area in Sargodha that lead to disturb the energy balance.
