Jordis Tradowsky

Position:                  Environmental (Atmospheric) Scientist/PhD Student

Email:                       jordis(at)bodekerscientific.com

Academic Qualifications:
  • MSc in Meteorology, Freie Universitaet Berlin, Germany
  • BSc in Meteorology, Freie Universitaet Berlin, Germany

Positions:

  • Aug - Sep 2017                            Running an atmospheric measurement campaign in Palau which is located in the Pacific Ocean  
  • March 2015 - present            PhD Student at the Freie Universitaet Berlin in cooperation with Bodeker Scientific and the New Zealand National Institute for Water and Atmospheric Research (NIWA)
  • Aug-Oct 2016                      EUMETSAT Radio Occultation Meteorology Satellite Application Facility Visiting Scientist at the Met Office, Exeter, UK
  • Sep-Oct 2015                      EUMETSAT Radio Occultation Meteorology Satellite Application Facility Visiting Scientist at the Met Office, Exeter, UK
  • March 2014 - Juny 2014       Internship at Bodeker Scientific
  • January 2013 - April 2013     Internship at the dutch research company TNO in Utrecht, The Netherlands.

Current Research:

  • Combination of measurements from different instruments into site atmospheric state best estimates.
  • Propagation of measurement uncertainties.
  • Tangent linear radio occultation retrieval and the estimation of structural uncertainties in the tangent linear radio occultation retrieval.
  • Development of a method to correct radiosonde temperature biases prior to assimilation into a numerical weather forecast system. Radio occultation bending angles are used as a reference and the Met Office operational numerical weather prediction system is used for the double differencing approach.
  • Ground-based reference quality measurements of the atmospheric state, e.g. radiosondes, ozonesondes, frost point hygrometer. 

Scholarships and Distinction:

  • March 2015 - 2017:               Doctoral Research Grant German Academic Exchange Service
  • 2015                                    AGU Outstanding Student Paper Award
  • 2013-2014:                           Several scholarships from the German Academic Exchange Service as part of the Transformation Partnership with Egypt
