Satellite-Based Monitoring of Shipping Emissions

Job description

As a Postdoctoral Researcher in Satellite-Based Monitoring of Shipping Emissions, you will develop innovative methods to detect and quantify emissions from individual ships using observations from space. Based in Wageningen, you will work at the interface of satellite remote sensing, atmospheric chemistry, atmospheric modelling and inverse methods.
You will contribute to a research programme with strong scientific and societal relevance: how accurately can we detect individual ship plumes from space, under which atmospheric conditions, and how can satellite observations be translated into quantitative ship-level emission estimates?
Within the Meteorology and Air Quality (MAQ) group, you will work under the supervision of Prof. Folkert Boersma and Prof. Maarten Krol and contribute to the AVES II and CAMS2_53c projects. You will further develop an existing Wageningen framework that combines satellite NO₂ observations, AIS-based ship activity, meteorological information and atmospheric modelling to identify ship plumes and estimate their NOₓ emissions.
Your duties and responsibilities include:
developing improved methods to detect and interpret ship plumes in satellite observations, including the use of plume-specific air mass factors and NO₂ profiles;
combining satellite observations, AIS-based ship activity, meteorological data and bottom-up emission estimates to identify and attribute pollution plumes to individual vessels;
investigating plume detectability and evolution under different wind, boundary-layer, background pollution, turbulence and photochemical conditions.
developing and applying inverse and data-driven methods to estimate ship emissions and distinguish ship-related pollution from other emission sources;
scaling up the analysis to large satellite and AIS datasets, contributing to automated workflows and a database of space-based ship-emission estimates, and communicating results through scientific publications and presentations.
The precise balance between these activities will depend on your expertise and interests and on the development of the projects.
Your team
You will work in the
Meteorology and Air Quality (MAQ) group at Wageningen University & Research. MAQ is an interdisciplinary research group working on atmospheric composition, meteorology, atmospheric modelling and Earth observation.
You will be part of a collaborative and international research environment in which satellite observations are combined with atmospheric models, meteorological data and data-driven methods. You will interact with researchers from different disciplines as well as with academic, governmental and other project partners.
The position is supervised by
Prof. Folkert Boersma and Prof. Maarten Krol and offers substantial opportunity to develop your own scientific ideas within the scope of the projects.

Requirements

You are a curious, creative and ambitious scientist who enjoys tackling challenging research questions and developing new methods. You are able to work independently while actively contributing to a collaborative research environment. You communicate clearly, critically assess scientific results, and are motivated to connect scientific research with real-world environmental challenges.
You also possess:
a PhD in atmospheric science, remote sensing, environmental science, meteorology, physics, or a related field;
experience working with satellite observations, preferably measurements of atmospheric composition such as TROPOMI;
experience with inverse modelling, emission estimation, data assimilation, or related quantitative methods;
a good understanding of atmospheric chemistry and transport, together with strong programming and data-analysis skills, preferably in Python;
strong scientific communication skills and the ability to work effectively across disciplines and with external partners.
Experience with meteorological reanalyses, atmospheric transport or chemistry-transport models, plume analysis, high-resolution modelling, AIS data, or machine-learning/data-driven methods would be an advantage.
In our international working environment there is an increasing amount of communication in English. For this position it is about language level
C1.
