Development of SVAT Models


Development of SVAT models has come from the convergence of two needs:

  • Meteorologists and climatologists need information on the heat and moisture input to the atmosphere from the earth's surface (e.g., soil, vegetation, water bodies) and how the surface extracts momentum and kinetic energy of the atmosphere through "friction".

  • Biophysicists and ecologists need information about the temperature, humidity levels, solar radiation, cloud cover, wind speed, precipitation, etc. to determine how plants and plant communities respond to environmental conditions.

    Prior attempts to link these two groups took the form of meteorologists using fixed vegetation conditions and plant physiologists using fixed climate conditions.
