About the VeWA consortium:

Goethe University Frankfurt and the Senckenberg Society for Nature Research invite applications for twelve research positions within the LOEWE consortium project VeWA (Past Warm Periods as Natural Analogues of our future 'high CO2' Climate); this includes eight PhD and four post-doctoral positions.

Via the LOEWE excellence initiative, the State of Hessen funds internationally visible research consortia with the aim of establishing thematic priorities.

What does VeWA focus on? We are investigating what conditions on Earth might be like under atmospheric CO2 concentrations more than double relative to pre-industrial times. The Paleogene (>35 million years ago) was the most recent geological period with similar atmospheric CO2 as predicted for the end of the 21st century. In VeWA, scientists from geology, geography, biology and climate modelling join forces to quantitatively investigate and model palaeoclimate and palaeoenvironment of the Eocene and late Cretaceous Periods. In 12 subprojects we will study marine and terrestrial proxy archives (e.g. calcifying organisms and sediments), including those of the Hessen World Heritage Site Messel, and compare these results to new state of the art climate model simulations. Our results will be shared through a public outreach initiative, including an exhibition at the Senckenberg Museum.

VeWA includes 12 positions focusing on the following subprojects and institutions:

About this position:

The Institute for Atmospheric and Environmental Sciences (Mesoscale Meteorology and Climate Research Group) invites applications for a fixed-term position - available on 1st May 2020 or soon thereafter - for a

PostDoc in Palaeoclimate Modeling (VeWA Project C1) (m/w/d)
(E13 TV-G-U, fulltime )

(39 months tenure)

The salary follows the Goethe University pay structure (TV-G-U).

This position is based on research within the LOEWE consortium VeWA, specifically subproject C1. Climate proxy data for the Paleogene (>35 million years ago, >2x[CO2]) indicate a significantly smaller latitudinal temperature gradient in the temperate zones than today. There is a lack of proxy data in the polar regions. The project C1 will contribute to improve the understanding of the energy transport processes in the paleoclimate system. In addition, it aims at better understanding of polar amplification in an ice-free world and of changes in mid-latitude atmospheric circulation. Methodologically, this project will rely on sensitivity studies and inverse modelling using a global climate system model.

An enthusiasm to help with some academic teaching is desirable. A contribution to the public outreach initiative of VeWA is envisaged.


Candidates with a Master's degree (MSc) in meteorology, oceanography, physics, mathematics or a related field and a PhD degree in one of the aforementioned areas should apply. Experience in performing and analysing experiments with a comprehensive climate system model is required. In addition, motivation and ability to participate in model development in an interdisciplinary and international environment is necessary. We expect a highly self-motivated student with excellent communication skills, both written and oral, in English. Furthermore, a general analytical (problem) solving skills, a willingness to occasionally work flexible hours, independence and organizational skills are expected.

Key to the success of VeWA will be cooperation and interaction amongst the VeWA researchers, co-PIs and PIs, as well as VeWA partners, such that teamwork and interpersonal skills are very important. The successful candidate will be trained in the relevant methods employed and supported by GRADE (Goethe Research Academy for Early Career Researchers). As part of VeWA, we offer excellent working conditions, an international multi-disciplinary working environment and excellent research infrastructure.

Goethe University is committed to equal rights and therefore we particularly encourage applications from female candidates and those from under-represented backgrounds. Equally qualified people with disabilities will be given priority.

Applications including a motivation letter, detailed CV, detailed description of research experience and interests (2 p. max), names and addresses of three scientific referees, should be sent as a single PDF document by e-mail to Ms. A. Radomilja Ruiz, RadomiljaRuiz@iau.uni-frankfurt.de, Institute for Atmospheric and Environmental Sciences, J.W. Goethe University, Altenhöferallee 1, 60438 Frankfurt am Main, Germany, by 9th March 2020. Interviews are scheduled for the end of March 2020. Informal inquiries regarding this position can be sent to Prof. Bodo.Ahrens@iau.uni-frankfurt.de
