PUMA logo

The Portable University Model of the Atmosphere is a circulation model in Fortran-90 developed at the Meteorological Institute of the University of Hamburg. PUMA originated in a numerical prediction model that was altered to include only the most relevant processes in the atmosphere. It serves as a training tool for junior scientists, allowing them to work with a program that is easier to understand and modify than ECHAM.


These pages are meant to document the current state of PUMA. You can download the sources from here, browse the reference paper or take a look at the results that have been achieved in PUMA runs.


You may also want to visit our ongoing project to produce a Planet Simulator, with one of its major components being PUMA-2, an extended version of PUMA that includes humidity and a boundary layer, among others.
