A cautionary tale of identifying the source of a methane plume over the North Sea
Data collected from the Facility for Airborne Atmospheric Measurements (FAAM) research aircraft has been analysed to try and identify the source of a plume of methane observed over the North Sea. A recently published article explains that initial analysis suggested the methane was being emitted from the gas field area, but important analysis of carbon isotopes in the methane revealed that leaked gas was not the main component of the plume.
FAAM is first to test fly 3D printed ice probe
The Facility for Airborne Atmospheric Measurements (FAAM) has made the headlines in the world of 3D printing after the research aircraft successfully tested a newly developed 3D-printed optical ice probe. The titanium instrument is able to detect the formation of ice particles by using optical fibres that emit light into any ice that has formed over the sensor head. If ice is present then the light will be reflected back and detected by the sensor.
Research into Southeast U.S atmosphere uncovers changing role of nitrogen oxide emissions in creating pollutants
Dr Pete Edwards from the National Centre for Atmospheric Science has carried out research into the chemical processes that occur in the night-time atmosphere in Southeast U.S. He found that the atmosphere is in a state of transition. In the past, the levels of pollutants in the air were dependent on the amount of nitrogen oxides, but now the atmosphere is becoming less controlled by nitrogen dioxides and therefore more similar to a pre-industrial atmosphere.
