Goethe University has recently installed a state-of-the-art measuring device at its Taunus Observatory near Frankfurt, Germany, to provide precise monitoring of halogenated greenhouse gases in the atmosphere. Continue reading F-Gas monitoring device installed at German observatory
Banned since 2010, CFCs have surprisingly and rapidly increased in the Earth’s atmosphere this last decade. CFCs have an atmospheric lifetime of 52 to 640 years and act as powerful greenhouse gases that also destroy the ozone layer. According to a recent study published in Nature Geoscience, the emissions of CFC-112a, CFC-13, CFC-113a, CFC-114a, and Continue reading CFCs on the rise again
The World Meteorological Organisation (WMO) has reported that ozone layer depletion reached record levels over large parts of the Arctic in spring. Monitored ozone levels over the Arctic in March are typically at least 240 Dobson Units (DU) – with a DU representing a 0.01mm-thick layer of pure ozone at standard temperature and pressure (STP). Continue reading Extreme weather, CFC damage result in record Arctic ozone depletion
VASA’S North American counterpart MACS has received reports of Chinese vehicles being sold into Uruguay with air-conditioning systems labelled as using the refrigerant blend R415b. This refrigerant is 25 per cent R22 (an ozone-depleting HCFC) and 75 per cent R152a (an A2-rated flammable HFC). It is reportedly installed in seven-seat minivan type vehicles sold in Continue reading Chinese vehicles using R415b?
