Integrated Model of Surface Processes


The Integrated Surface Processes Model (Inland) is the surface package of the Brazilian Model of the Global Climate System. The Inland project is coordinated by Marcos Heil Costa (UFV) and Gilvan Sampaio (INPE), with funding from the Rede Clima and INCT programs of the Ministry of Science, Technology and Innovation.

When completed, Inland will represent several superficial processes:

1. Canopy biophysics, including water and energy balance, ice formation, turbulence and aerodynamics;

2. Plant physiology, including light interception, photosynthesis and respiration, canopy conductance and interactions with soil fertility;

3. Soil physics, including water and energy balance, infiltration, runoff, and deep drainage;

4. Short term vegetation dynamics (phenology);

5. Long-term vegetation dynamics, including GPP, NPP, carbon allocation, primary and secondary growth, mortality and competition between functional types of plants;

6. Disturbances and fires;

7. Phenology and management of agricultural crops, including dates of planting, emergence, growth, grain filling, senescence and harvest;

8. Soil biogeochemistry, with different levels of complexity for soil carbon, nitrogen and phosphorus;

9. Surface hydrological processes, including rivers, lakes, and flooded areas.

The model is forced by hourly weather data (point version) or regional or daily or monthly weather data (grid version), or it can be coupled with regional or global atmospheric models.

INLAND is based on the IBIS – Integrated Biosphere Simulator model, developed by the University of Wisconsin-Madison.
