Describing pollutant distribution in 3d

Envirotec Magazine

A team led by environmental physicist Stefan Schreier at the University of Natural Resources and Applied Life Sciences in Vienna is attempting to build up a better picture of nitrogen dioxide pollution in the city. The group is using MAX-DOAS instruments mounted on top of buildings to build a more accurate map of pollutant distribution.

Air and noise quality study will help inform Oxford City’s future environmental policy approach

Envirotec Magazine

The new ‘OxAria’ study started on 1st July, extending an existing collaboration which has enabled five low-cost air pollution sensors to be installed at city centre locations, generating real-time information on key air pollutants, including nitrogen oxides (NO, NO2), carbon monoxide (CO), ozone (O3) and particulate matter (PM1, PM2.5,

UK substantially underestimates its methane emissions from oil and gas production – and many other countries probably do too

Envirotec Magazine

Due to its climate and indirect health impacts (methane is a precursor for ozone which is an air pollutant that damages human health and crops), methane mitigation has recently become a global policy priority.

US, China commit to phase down climate-warming HFCs from refrigerators and air conditioners – but what will replace them this time?

Renewable Energy World

CFCs were destroying the ozone layer high in the Earth’s atmosphere, which is essential for protecting life from the Sun’s harmful ultraviolet radiation. But when they break down, they create chlorine that reacts with the protective ozone, letting dangerous radiation through to the Earth’s surface. How HFCs keep rooms and food cool.
