"Thank you for actually penning these books. They are a wonderful review of the concepts without the excessive (but necessary) amount of math behind them. I wish they had been recommended as supplements in both my undergrad and graduate years."

— Josh Tobias, 2017

Weather Graphics is proud to present Clima-Sim, the only "build your own" climate modeling software available for Windows. It is written by Tom Ehrensperger, who holds an MS in physics and authored the WX-SIM weather simulator software. Clima-Sim is a gridpoint model that forecasts changes in climate: that is, the long-term averages of temperature, solar radiation, cloud cover, and albedo. It won't solve the global warming debate, but it will allow you to simulate the global circulation, adjust a plethora of astronomical, physical, and chemistry parameters for the Earth, and see how this plays out on daily, monthly, and annual temperatures for a typical year.
