Land models are computer simulations used to represent and study the interactions between the Earth's surface and the atmosphere. These models incorporate various components such as vegetation, soil, water, and land use, to simulate processes like energy and water exchange, carbon cycling, and nutrient cycling in terrestrial ecosystems. Land models are critical tools for understanding the impacts of land use and climate change on the environment, as well as for predicting future changes in vegetation patterns, water resources, and ecosystem dynamics. They are often used in conjunction with climate models to improve our understanding of the Earth's complex systems and inform decision-making for land management and conservation.
