The most important greenhouse gases monitored by NILU – The Norwegian Institute for Air Research continued to rise in 2017. Levels have now reached new records both at Svalbard and in Aust-Agder in Norway. Both CO2, methane and nitrous oxide continue to increase in both Southern Norway and Svalbard, and there is no sign of reduction or flattening in this trend.
Over a period of 4 months, NILU has measured the concentrations of volatile organic compounds (VOCs) in the air in the Chilean municipalities of Quintero-Puchuncaví and Concón in the Valparaíso region. The measurements were carried out on behalf of the Chilean Ministry of the Environment. So far, the measurement results show no sign that VOC emissions from the industrial area affect the air quality in neighbouring residential areas.
NILU ha realizado mediciones de compuestos orgánicos volátiles (COVs) durante un periodo de cuatro meses en los municipios de Quintero-Puchuncaví y Concón, ambos en la región de Valparaíso. Estas mediciones fueron comisionadas por el Ministerio de Medio Ambiente de Chile. Los resultados obtenidos hasta el momento no indican que las emisiones de COVs de la zona industrial afecten la calidad del aire en las áreas residenciales cercanas.
In a new paper published in Scientific Reports today, scientists from NILU and other leading international partners show that global climate models are able to reliably calculate historical sulfur trends in accordance with observations.
August 31st, 2018: More than thirty scientists from all over the world, in conjunction with regulators from agencies across the globe, have jointly outlined a set of needs, goals, and actions to help assess and manage the diverse and widely used group of per- and polyfluoroalkyl substances (PFASs) in the future.
Air quality in Europe is getting better. However, a significant proportion of Europe’s population still lives in cities and areas where at times, noise and air pollution may lead to health problems. Norwegian scientists are now tasked with leading the work of compiling the knowledge base the decision-makers in Europe need to give us better air and quality of life.
From the NILU Annual Report 2017: During the last decade, the need for information and data has exploded, and this “data revolution” has not stopped short of science. In environmental research, data have become more and more important – to the point that scientists now even know what your fireplace looks like.
A new study in Nature Geoscience unveils a need of revising previous ethane and propane emissions studies, as these emissions have been underestimated by more than 50%. Such revision could in turn improve our understanding of the forceful and related methane emissions, still largely enigmatic to atmospheric sciences.
