PPT《WELCOMEto the PRACTICAL EXERCISES》

WELCOMEto the PRACTICAL EXERCISES * For the practical exercises you have got a TUTORIAL, with which you can work most of the time on your own.

There are

6 lessons, in which you will learn aboutInstallation of the COSMO-CLM model package (Tutorial Chapter 1)Preparing External, Initial and Boundary Data (Tutorial Chapter 2)Running the COSMO-CLM in a step-by-step mode (Tutorial Chapter 3)Postprocessing and visualizing netCDF files (Tutorial Chapter 5)Running the COSMO-CLM in a chain mode (optional, Tutorial Chapter B.3)Practical exercisesoptional session together with NWP group: Idealized test cases Extra sessions on 24/25th Feb. on Community Land Model and COSMO-ART Overview * Introduction * The Starter Package is the basis of the exercises in this trainings coursecontains everything that is necessary to perform a climate simulation on a UNIX system (except the netCDF Library)keeps everything under one main directory cclm-sp can be used to learn how all parts of a climate simulation work togethercan be used as template for your own simulationwill be made available under http://redc.clm-community.eu/projects/cclm-sp * CLM-Community + Support model development and coordination of activities in CLM community ? www.clm-community.eu if you want to use the model ? get memberplease do not take the code home if you are not a member!!!support in the usage in different ways: (see homepage)TutorialForum+Wikibug reporting systeminformation on namelist parameterstool for preparing initial and boundary datafurther utilities * Namelist Tool for a new model simulation you need to think about namelist settingsinformation on the namelist parameters: see '
