STAR - STAtistical Regional model
STAR was developed to generate regional climate projections for the near future (for the next 50 – 60 years). Since it basically generates a date-to-date mapping by which a date from the observational period is assigned a date of the future projection-period, not only projections of station data but of any kind of mete-orological/climatological observation can be obtained. STAR is constrained by a prescribed linear temperature trend (or by trend of another parameter) only which makes it independent on complex GCM output. Because of the short CPU time STAR can calculated a large number of realizations to estimate uncertainties of future developments.
Who maintains it?F.-W. Gerstengarbe, P.C. Werner, B. Orlowsky, D. Hauffe
What are the next steps in the development of the model architecture?
Extension of the constraints to circulation pattern statistics in combination with flexible segment lengths for the date-to-date mapping.
In what way is the model different from other models in the community?STAR does not need a GCM as a driver. It delivers not only meteorological projections but any kind of interesting observations, e.g. river runoff or circulation indices, if they are provided for the observational period.

The first version of STAR and its basic philosophy were published in 1997: Werner, P.C., Gerstengarbe, F.-W., Proposal for the development of climate scenarios. Climate research 8,3,171-180
Some remarks on application of model STAR and its climate scenarios:- The data calculated by STAR were used as input for 11 models in the project GLOWA-Elbe. From that, a considerable number of papers were published by project members which used the STAR simulations (see also www.glowa-elbe.de/german/publications_wiss.htm).
- Moreover, STAR was applied in the projects WAVES, KLIWA, KLARA and in different regions of Germany (BW, NRW, Brandenburg) and the world (China, NE-Brazil, Israel/Palestine, Tajikistan, Czech Republic).
- Actual, STAR is part of the projects GLOWA-Elbe, CLIMREG - Climate Impacts Register for Germany, “Auswirkungen des Klimawandels auf die Schadenssituation in der deutschen Versicherungswirtschaft“ and of about 15 project proposal.
- STAR-data were/are used at several research institutes and universities.
