Long-term observations of reactive gases in the troposphere are important for understanding
trace gas cycles and the oxidation capacity of the atmosphere, assessing impacts of …

In order to expand current atmospheric methane monitoring capabilities, we investigated the
performance of an off-the-shelf, low-cost, metal oxide based methane (CH 4) gas sensor. A …

Abstract The Benguela Upwelling System (BUS) is the most productive of all eastern
boundary upwelling ecosystems and it hosts a well‐developed oxygen minimum zone. As …

Abstract Eastern Boundary Upwelling Systems (EBUSs) are coastal hotspots of the potent
greenhouse gas nitrous oxide (N2O). However, estimates of their emissions suffer from large …

An optimal network design was carried out to prioritise the installation or refurbishment of
greenhouse gas (GHG) monitoring stations around Africa. The network was optimised to …

A combination of the path length enhancement provided by cavity ring-down spectroscopy
together with the selectivity and noise suppression capabilities of Faraday rotation …

Ground-based atmospheric observations of CO 2, δ (O 2/N 2), N 2 O, and CH 4 were used to
make estimates of the air–sea fluxes of these species from the Lüderitz and Walvis Bay …

A continuous measuring system for atmospheric O2/N2 ratio was developed employing a
paramagnetic oxygen analyzer. Sample air is allowed to flow through a water trap cooled …

A gas analyzer has been developed using cavity ring‐down spectroscopy (CRDS)
technology, designed to simultaneously measure the concentrations of CO2 and CO. These …

We developed a high-precision oxygen measurement system with long-term stability using a
magneto-pneumatic oxygen analyzer for atmospheric observations. A high precision of 1.4 …
