Simulations of Daisyworld on a Fractal Terrain with Realistic Height Field Parameter Dependencies

Abstract

The Daisyworld model is an abstract palaeoclimatological approximation of self-regulating, global surface temperatures. It demonstrates some aspects of the the Gaia hypothesis, which proclaims the earth is a complex system which can sustain life through feedback loops. A simulated Daisyworld relies on the reflection coefficient (albedo) of two hypothetical populations; white daisies, which thrive in warm conditions but reflect most sunlight, permitting surface cooling and black daisies, which prosper in cooler temperatures, but increase surface temperature with the absorption of sunlight. In this work, atmospheric variability as determined by latitude, longitude and altitude is introduced to the Daisyworld model, along with an increase in the resolution of the simulation itself. The purpose is to identify micro-climates and the effects a fractal terrain that includes a realistic height field can have on self-regulation and the sustainability of life.
