Positions

2018-2019 Visiting/associate Scientist, UK Met Office, Exeter, England.

During 2018/2019 I spent 4 months working with the EUMETSAT Radio Occultation Meteorology Satellite Application Facility. Within this period I spend two months at the Satellite Applications department of the UK Met Office.

2018– current Atmospheric Scientist, Bodeker Scientific, Alexandra, New Zealand.

2015–2018 Atmospheric Scientist/PhD Student, Bodeker Scientific, Alexandra, New Zealand.

During my doctoral thesis, I worked as an atmospheric scientist at Bodeker Scientific. I addition to the research I conducted for my thesis, I supported the Global Climate Observing System Reference Upper-Air Network (GRUAN) and worked on a variety of funding proposals.

2017-2018 Meteorologist, BK Scientific, Mainz, Germany.

I am employed part-time as a meteorologist to organise and perform atmospheric measurement campaigns at the Pacific Island state of Palau, where I launched ozonesondes and radiosondes in support of the European StratoClim project. This role also involved educating children from a Palauan school and performing balloon launches with them.

2016 Visiting Scientist, UK Met Office, Exeter, England.

During 2016 I spent 2.5 months as a visiting scientist at the Satellite Applications department of the UK Met Office. The project was organised and funded by the EUMETSAT Radio Occultation Meteorology Satellite Application Facility.

2015 Visiting Scientist, UK Met Office, Exeter, England.

During 2015 I spent 2 months as a visiting scientist at the Satellite Applications department of the UK Met Office. The project was organised and funded by the EUMETSAT Radio Occultation Meteorology Satellite Application Facility.

2014 Intern, Bodeker Scientific, Alexandra, New Zealand.

After finishing my Master of Science in Meteorology I spent 4 months working as an intern at Bodeker Scientific. Following this internship I developed a funding proposal to return to Bodeker Scientific as a PhD student.

2013 Intern, TNO, Utrecht, The Netherlands.

As part of my master’s thesis I spent 4 months at TNO, which is an indepent research organisation specialised in applied research. The resulting thesis was titled “Influence of meteorology on the LOTOS-EUROS model performance and on the data assimilation of NO2 satellite observations”.

2011 Intern, Senate Department for Health, Environment and Consumer Protection; Directorate III; Environment Policy, Berlin, Germany.

Internship in the air quality and emission working group as part of my Bachelor degree. I mainly analysed the exceedance of threshold values for air pollutants in Berlin and the cause of the prevailing exceedance.

Current Research

Attribution of the impacts of anthropogenic climate change on extreme weather events. Lead of the Extreme Weather Event Near Real-time Attribution Machine (EWERAM). EWERAM conducts the research necessary to develop a tool that, within days after an EWE, provides scientifically defensible data to inform quantitative statements about the role of climate change in both the severity and frequency of the specific event.
Developing a new approach for inferring air pollution maps in cities, specifically providing the organisation and oversite to the MAPM field campaign performed in Christchurch during winter 2019. The campaign included measurements of particulate matter with 64 instruments distributed throughout the city and additional meteorological measurements.
Ground-based reference quality measurements of the atmospheric state, e.g. radiosondes, ozonesondes, frost point hygrometer.
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.

Measurement campaigns

Jordis has participated in and, in some cases led, measurement campaigns on four continents, i.e. Europe, Asia-Pacific, Africa, and Australia. The campaigns were ranging from student-organised field campaigns, to large-scale measurement campaigns including a variety of partners. Below is a list of those campaigns organised and led by Jordis.

An ozonesonde campaign at the Palau Atmospheric Observatory during August/September 2017 as part of the European StatoClim project (http://www.stratoclim.org/).
A second ozonesonde campaign at the Palau Atmospheric Observatory during August/September 2018. During this measurement campaign Jordis extended the outreach to the Palau High School and involved the students into the balloon launches.
The MAPM (Mapping Air Pollutions eMissions) campaign taking place in Christchurch from June to September 2019 (http://www.mapm.co.nz/mapm-measurement-campaign/).
