Abstract

Climatic and Terrain parameters which include the soil moisture, precipitation, evapotranspiration, maximum and minimum temperature are the most crucial factors which drives the future of earth. Soil Moisture regulates the movement of water and heat energy between the land surface and the atmosphere through evaporationn and plant transpiration. Precipitation controls the entire operation of the hydrosphere. Evapotranspiration is crucial for agricultural irrigation and water resource management. Land surface temperature (LST), which is crucial for monitoring crop and vegetation health, calculating the net radiation budget at the Earth's surface. The parameters of the delineated study area (Ranchi and Khunti districts, Jharkhand, India) data were retrieved from Terraclimate dataset for the years 1990 - 2020. The dataset was refined, and Mann Kendall trend analysis was implemented, and the trend graphs were prepared to determine the change in trend and relationship. The graphs generated shows the changes (positive or negative) in trend in every pixel for the 31 years for every month.
