The following programs were created in order to provide a practical means for enhancing the knowledge base of students studying environmental biophysics. All of the programs were used in the course of the same name taught to undergraduates at Washington State University. The programs are intended to serve as supplements to other readings, and for this purpose, the book by G.S. Campbell and J.M. Norman, 1998, An Introduction to Environmental Biophysics, Springer Verlag, NY, is suggested for its continuity with the brief explanations provided in each program.

Each of the following programs may be downloaded as an XLS (Microsoft Excel) format file compressed as a zip file. Each of the files contain discreet modules for source code, instructions, and data modeling. The Visual Basic source code is intended to run from within Excel. Unless otherwise noted, these models were developed by Gaylon S. Campbell (retired) and associates.

	Program for the investigation of photosynthesis using the Collatz et. al (1991) photosynthesis simulation model.
	Program which simulates the temperature profile in a soil when the temperature of the soil surface follows a sine curve.
	Program which allows you to experiment with a leaf's energy budget and leaf transpiration equations in order to gain an appreciation for the ways in which leaves respond to their environments.
	Program for simulating evaporation processes beneath tree canopies.
	Program for simulating the energy budget and climate space of an animal.
