The following programs were implemented by the Hands-On Climatology Team  at the Geological Sciences Department at the University of Texas at Austin.
The programs may require Java[TM] plug-in for Applets. Click here to download the plug-in if the programs do not run in your browser.

The programs were written in Java based on the BASIC programs in McGuffie and Henderson-Sellers (1997). This site is developed for use by educators and general public. When using or linking to the programs, we ask that you acknowledge the Climate Science Program at the Geological Sciences Department at the University of Texas at Austin.

These programs:

  • are interactive
  • depict climate processes graphically

    1. Daisy Model  


This Program models a planet Daisyworld.

Daisyworld is an artificial world having a very simple biota which is specifically designed to display the characteristics in which we are interested - namely, close coupling of the biota and the global environment (McGuffie and Henderson-Sellers,1997).


LandUse Model



This Program helps you calculate the globally averaged temperature change caused by human-induced  surface albedo change (McGuffie and Henderson-Sellers, 1997). landuse_problems.html
   3.  Ocean Model


This is a simple box-diffusion model of the atmosphere-ocean system based on a full numerical solution of the equations described in Wigley and Schlesinger (McGuffie and Henderson-Sellers, 1997). ocean_problems.html
   4. EBM This Model is similar to those of Budyko and Sellers.

You will be offered the opportunity to alter the values of the parameters which control the model climate (McGuffie and Henderson-Sellers, 1997).

The funding for this project came from Mr. Harry Lucas, Jr. through Educational Advancement Foundation. More models will be included if there are more funds available.
