SITE Model: Fortran Code and Input Data for Tropical Forest Fluxes

From 2002 to 2003, meteorological and flux data were collected at the km 67 Tapajos National Forest site in Para, Brazil. This dataset provides the Fortran source code (version 1.1-0d) and hourly input data for the Simple Tropical Ecosystem Model (SITE), a point model simulating CO2, water, and energy fluxes. The model incorporates processes like radiation balance, plant physiology, transpiration, and soil moisture dynamics.

Use Cases

• Calibrating and running the SITE model for tropical ecosystem flux simulations based on the provided Fortran code.
• Analyzing hourly meteorological forcing data, including temperature, wind, precipitation, and radiation, from a Brazilian tropical forest site.
• Studying the coupling of carbon, water, and energy balance processes in a simplified canopy-soil model structure.
• Comparing model outputs against observed flux data described in the companion documentation file.

Strengths

• Includes the complete, versioned (1.1-0d) Fortran source code for the published SITE model.
• Provides documented, site-specific hourly forcing data collected over a full year (2002-2003).
• Model incorporates multiple biophysical processes (radiation, aerodynamics, physiology, hydrology, carbon).

Limitations

• Key metadata conflicts: last update date is reported as both 2003-08-28 and 2026-04-10.
• Dataset size, row count, and specific column names are not provided in any source.
• The license is specified only as 'other-license-specified' without further detail.
