Our Past Global Change research group mainly interested in the area of modeling Climate and Global Change. The Program focus on observing understanding, modeling, and predicting climate variability and change on seasonal and longer time scales. Documenting and analyzing past climate change in order to understand the full range of natural variability in the earth system, thus resulting in more accurate climate predictions. According to our Critical_Zone Observing and Monitoring to establish a numerical model to characterize the coupled physical, chemical, and biological processes cycles that cause to global climate change. The successful applicant will be working as an integral part of a motivated multidisciplinary team within the CUG and external academic partners. Tasks also include scientific publication and presentation.
