Mapping near-surface NO2 concentrations in urban areas by combining in situ and remote sens-ing observations with city-scale transport simulations

NO2 is a primary air pollutant with a high spatial and temporal variability. Therefore, high-resolution maps are critical for linking NO2 exposure and health impact. In the Munich NO2 imaging campaign, NO2 was measured with airborne and ground-based in-situ and remote sensing instruments. In this project, you will analyse the MuNIC dataset and develop an algorithm to convert APEX NO2 maps to maps of near-surface NO2 concentrations.

A model study on monitoring CO2 emissions of cities from high-altitude pseudo satellites

High altitude pseudo satellites are self-sustaining, unmanned air vehicles that fly in the stratosphere (~20 km above the ground) and can be kept in a stationary position (e.g., above a city) for several weeks to months. In this project, you will perform an observing system simulation experiment (OSSE) to answer the question how accurately a HAPS-based imaging spectrometer would need to measure CO2 to be able quantify the CO2 emissions of a city.

Data Engineering Intern

We are searching for a Data Engineering Intern for the ICOS Cities project (involving an outdoor carbon dioxide (CO2) sensor network) with strong skills in Python, SQL, and software-design architecture knowledge. You will drive further development of our current data pipeline that processes and visualises time series data from our CO2 sensor network. You will work closely with postdoctoral researchers and scientists to refactor the current Python data processing pipeline to be more maintainable, portable, reliable, and to allow for future enhancements. Your work will strongly contribute to an observation based assessment of the greenhouse gas emissions of the city of Zürich on its path to NetZero.

Quantifying CO2 and NO2 emissions of cities and power plants from satellite observations

In this project, you will quantify the CO2 and NO2 emissions of cities and power plants from the new Sentinel-5P TROPOMI satellite that provides high-resolution images of NO2 emission plumes.
