Tropical Monsoon Forest Thermodynamics Based on Remote Sensing Data

Area of Science:

• Thermodynamics
• Ecology
• Forest Science

Background:

• Solar energy transformation is crucial for ecosystem function.
• Deciduous tropical forests play a significant role in global energy balance.
• Understanding thermodynamic variables is key to characterizing ecosystem processes.

Purpose of the Study:

• To analyze thermodynamic variables governing solar energy balance and structure in tropical forest ecosystems.
• To define distinct thermodynamic states and sub-systems within these forests.
• To correlate thermodynamic system types with landscape cover and seasonal changes.

Main Methods:

• Analysis of seasonal dynamics of thermodynamic variables.
• Determination of two main thermodynamic system states (drought and wet seasons).
• Definition of balance and structural bioproductional sub-systems.
• Classification of thermodynamic systems based on variable invariants and landscape cover.

Main Results:

• Two primary thermodynamic states were identified: end of drought season and end of wet season.
• Two sub-systems, balance and structural bioproductional, were defined for solar energy transformation.
• Thermodynamic system types correlated with different landscape cover classes.
• Seasonal variations in thermodynamic variables were observed across different system types.
• Forest canopies were found to be approximately 4°C cooler than open areas year-round.

Conclusions:

• The study provides a thermodynamic framework for understanding solar energy dynamics in tropical forests.
• Thermodynamic system classification offers insights into landscape cover and ecosystem function.
• The observed temperature difference highlights the significant microclimatic influence of tropical forests.
