The
National Center for Atmospheric Research Land Surface Model (LSM) is a unidimensional computational model developed by Gordon Bonan that describes ecological processes joined in many
ecosystem model
An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the re ...

An atmosphere () is a layer of gas or layers of gases that envelop a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A s ...

This model has a simplified treatment of the surface flows that reproduce at the very least
computational cost the essential characteristics of the important interactions of the land-atmosphere for climatic simulations.
As the types of surface vegetated for some species are several, have a standardization of types of covering being enclosed surfaces covered with water as lakes (amongst others); thus the model wheel for each point of independent form, with the same average of the atmospheric interactions. The model functions in a space grating that can vary of a point until global.
