Atmospheric Physics and Chemistry Group (APCG)

Welcome

Welcome to the homepage of the Atmospheric Physics and Chemistry Group (APCG) of the Institute of Marine and Atmospheric research Utrecht (IMAU)!

The Atmospheric Physics and Chemistry Group (APCG) studies the chemical composition of the atmosphere, the change in its composition due to anthropogenic emissions, and interactions between atmospheric chemistry and the Earth's climate. Our research focuses on global trace gas budgets, emissions from the biosphere and aerosol-cloud interaction. As tools we use measurements, both in the atmosphere and in the laboratory, and computer models of various complexity.

It is our mission to combine world-class atmospheric research with education of the next generation atmospheric scientists.

The APCG is part of the Institute of Marine and Atmospheric research Utrecht (IMAU) at Utrecht University, The Netherlands.

Our group is currently involved in the European Training Network MEthane goes MObile - MEasurements and MOdelling (MEMO2). We have two PhD positions open within this project.

Research topics

Isotopic Measurements

We investigate atmospheric trace gas cycles using experimental isotope techniques.

Reactive Organic Trace Gas Measurements

We quantify the emissions of reactive organic trace gases from the biosphere, and their role in aerosol formation and pollution.

Chemistry-Aerosol-Climate Interactions

We study greenhouse gas abundances and lifetimes in the atmosphere, and feedbacks between air pollution and climate using state-of-the-art chemistry and climate models.

Inverse Modelling

Quantifying the budgets of atmospheric constituents is essential for understanding their current concentrations and predicting their future evolution.
