[Met-jobs] Postdoc position in SFB/TR172 Arctic Amplification (University of Cologne)

From Kerstin Ebell <>
Date Tue, 7 Jan 2020 14:59:51 +0100

Dear all,

the Institute for Geophysics and Meteorology, University of Cologne, invides applications for a postdoc position on the topic
"Variability of Arctic clouds from ground-based sensor synergy".
(see also official job announcement in the attachment)

The position is funded within the Collaborative Research Center TR172 Arctic Amplification (AC)3 (, whose second phase has started in January 2020. The overall goal of this position is to analyze Arctic cloud properties from ground-based remote sensing observations particularly for the site Ny-Ålesund and compare them to observations of other Arctic sites.

The position is available from now on a full-time basis. It is limited to 31 December 2023. If the applicant meets the relevant wage requirements and personal qualifications, the salary is based on remuneration group 13 TV-L of the pay scale for the German public sector.

Project topic:
During Phase I of AC³, a W-Band cloud radar has been installed at the German/French research site in Ny-Ålesund/Svalbard and has collected a first long-term dataset of Arctic clouds. The successful candidate will continue the time series of cloud observations at Ny-Ålesund and analyze the long-term statistics of clouds at this site. To asses the spatial variability of liquid water path and integrated water vapor on a local scale, scanning microwave radiometer (MWR) measurements will be investigated. The cloud observations at Ny-Ålesund will also be set into context to measurements of the MOSAiC (Multidisciplinary Observatory for the Study of Arctic Climate), COMBLE (Cold-Air Outbreaks in the Marine Boundary Layer Experiment) and aircraft activities within TR172. To this end, the successful candidate will develop and apply consistent MWR retrieval algorithms for the different instruments at the different locations. He/she will also compare the cloud observations at Ny-Ålesund to long-term observations at other Arctic sites, e.g. Barrow (Alaska) and Summit (Greenland). Satellite-based cloud measurements will be exploited to set the site-specific information in a broader context.

Your tasks:
- Develop and apply retrieval algorithms in particular for microwave radiometers
- Jointly analyze cloud radar, microwave radiometer and further data from remote sensing measurements
- Set the long-term measurements in Ny-Ålesund in con- text to campaign observations, e.g. MOSAiC and to observations of other Arctic cloud observatories, e.g. at Barrow
- Active participation in research communication (seminars, conferences, publication in international journals)

Your profile:
- PhD in Meteorology or a related field
- strongly experienced in atmospheric remote sensing
- advanced state of the art programming experience, UNIX or LINUX operating system
- high willingness to collaborate with scientists in- and outside of TR172 and to establish new scientific cooperations
- abilitiy to work in a team as well as independently
- very good communication skills in written and spoken English

We offer you:
- working with an internationally well-established working group
- a diverse and fair working environment
- support in reconciling work and family life
- flexible working time models
- extensive advanced training opportunities
- occupational health management offers
- local transport ticket at a discount for UoC employees

Please send your convincing application including a motivation letter describing background, training, research interests, and motivation for this position; your CV, certificates and the contact information of two referees all merged into a single PDF via email to Kerstin Ebell ( with the reference number Wiss2001-02.

The application deadline is 31 January 2020.

Best regards,
Kerstin Ebell
