In North Africa, sediment proxies such as palygorskite and the kaolinite-to-chlorite ratio are usually transported as dust components. Their relative increase or decrease is indicative of an arid or humid condition respectively.\r\nAnother way to understand palaeoclimate conditions is by the use of coupled atmospheric models within the Paleoclimate Modelling Intercomparison Project Phase III (PMIP3). In PMIP3, Global Climate Models (GCM), such as MPI-ESM (Max-Planck-Institute Earth System Model), simulate past climate conditions.\r\nThis thesis provides a preliminary comparison of the sediment proxies with the MPI-ESM simulations of precipitation and temperature for the LGM (last glacial maximum) and mid-Holocene in North Africa. By comparing proxy and model data, a positive correlation between proxies and model results can be assigned as the result of this thesis.","type":"researchdata_literature","resources":[{"description":"","format":"PDF","url":"http://afs/rrz.uni-koeln.de/project/sfb806db/Phase_1/E/E6/data/000/Ehimen_Williams_IMES-Thesis.pdf","created":"2015-02-02T10:32:16.265699","state":"active","package_id":"4f93dd2e-2ed1-4eae-8104-9ca32e81290e","last_modified":"2021-10-16T11:10:03","id":"587c40c8-d17f-4613-a40e-e7f8fdb177ac","name":"Ehimen_Williams_IMES-Thesis.pdf"}],"tags":[],"extras":[{"key":"bibtex:address","value":""},{"key":"bibtex:author","value":"Ehimen Ebhohimen Williams"},{"key":"bibtex:booktitle","value":""},{"key":"bibtex:citation","value":""},{"key":"bibtex:doi","value":""},{"key":"bibtex:editor","value":""},{"key":"bibtex:howpublished","value":""},{"key":"bibtex:isbn","value":""},{"key":"bibtex:journal","value":""},{"key":"bibtex:month","value":""},{"key":"bibtex:number","value":""},{"key":"bibtex:organization","value":""},{"key":"bibtex:pages","value":""},{"key":"bibtex:publisher","value":""},{"key":"bibtex:school","value":"University of Cologne"},{"key":"bibtex:series","value":""},{"key":"bibtex:type","value":"mastersthesis"},{"key":"bibtex:key","value":""},{"key":"bibtex:url","value":""},{"key":"bibtex:volume","value":""},{"key":"bibtex:year","value":"2014"}],"groups":[{"image_url":"http://crc806db.uni-koeln.de/fileadmin/template/images/projects/imageE6.png","name":"e6"}],"author":" Patrick Ludwig","author_email":false}{"help":"Update a dataset (package).\n\n You must be authorized to edit the dataset and the groups that it belongs\n to.\n\n Plugins may change the parameters of this function depending on the value\n of the dataset's ``type`` attribute, see the ``IDatasetForm`` plugin\n interface.\n\n For further parameters see ``package_create()``.\n\n :param id: the name or id of the dataset to update\n :type id: string\n\n :returns: the updated dataset (if 'return_package_dict' is True in the\n context, which is the default.
