PlaSim School: Hamburg model attracts international scientists to the KlimaCampus


The Planet Simulator can simulate 400 years of climate development in a single day - on a normal computer. Around 40 scientists and students wanted to become acquainted with this flagship at the Meteorological Institute and have registered for the first PlaSim School at the KlimaCampus. The international workshop takes place from April 17th to 19th. The participants are from the fields of meteorology, astronomy, mathematics and theoretical physics.

In presenting the workshop, the Hamburg meteorologists not only impart insight into the theory of the model but also give the participants the opportunity to conduct their own experiments with the planet simulator. For example, they calculate the effect of Tibet´s high plateau on the monsoon and how conditions would differ if it didn´t exist. However, the Planet Simulator can do more than just display conditions on Earth. If changes are made in the orbit, geometry and composition of the atmosphere, the participants can also simulate conditions on other planets, such as Mars and Venus.

"The Planet Simulator is very user-friendly", says Dr. Hartmut Borth from the Meteorological Institute, one of the organizers of the PlaSim School. "Parameters such as CO2 or the solar constant are simply put in using the graphic interface. The user then already receives graphics and visualized data during the calculation process." The system is very fast and allows for long model runs.

As an open source project, the Planet Simulator is available to interested persons worldwide. In contrast to highly resolving prognostic models, it needs relatively little computer power. "That is definitely a practical advantage. The participants in our workshop can take the model back home with them on an USB-Stick“, according to Borth.
