New European measurement network accurately follows all non-CO2-greenhouse gases

/ September 17, 2015/ Atmospheric Physics and Chemistry, IMAU

Prior to the political summit in Paris at the end of this year, Utrecht University will be hosting an international scientific conference on non-CO2 greenhouse gases from 21-24 September 2015. These gases are estimated to be responsible for approximately one-third of global warming. The conference will conclude the successful European InGOS project that was coordinated by ECN in the Netherlands.

PhD defense: Variations in the atmospheric methane budget after the Mount Pinatubo eruption

/ June 16, 2015/ Atmospheric Physics and Chemistry, IMAU

Narcisa Banda, 1 July 2015, 12:45 pm, University Hall, Domplein 29, Utrecht Promotores: Prof. dr. M.C. Krol and Prof. dr. T. Röckmann Co-promotores: Dr. T.P.C. van Noije and Dr. M. van Weele Methane is the second most important anthropogenic greenhouse gas. Methane concentrations in the atmosphere have been increasing since the 1700s due to anthropogenic emissions. This increase slowed down

PhD defense: Study of the hydrological cycle using satellite-borne isotopologue measurements and model results

/ June 16, 2015/ Atmospheric Physics and Chemistry, IMAU

Samuel Jonson Sutanto, 22 June 2015, 12:45 pm, University Hall, Domplein 29, Utrecht Promotor: Prof. dr. T. Röckmann Several phase changes, from evaporation to condensation, during transport of water vapor leave a characteristic imprint on the isotopic composition of water vapor and the corresponding precipitation. This is a main reason that PhD student Samuel Sutanto used the water isotopologues to

Utrecht University hosts InGOS International Conference about Non-CO2 Greenhouse Gases

/ June 15, 2015/ Atmospheric Physics and Chemistry, IMAU

It is our pleasure to invite you to the 1st International Conference on Non-CO2 Greenhouse Gases (InGOS) and how observations can help to mitigate climate change. The emissions of non–CO2 greenhouse gases (NCGHGs) such as CH4, N2O, SF6, H2 and halocarbons are very uncertain and it is as yet unknown how future climate changes will feedback into these emissions. Nevertheless,

Luchtkwaliteit meten op Europese schaal

/ June 8, 2015/ Atmospheric Physics and Chemistry, IMAU

Welke invloed heeft luchtverontreiniging op wolken die op hun beurt weer het klimaat beïnvloeden? Dat wil het Europese samenwerkingsproject ACTRIS-2 waar het KNMI aan deelneemt, op een gecontroleerde en structurele manier meten en onderzoeken. Deze week is het project ACTRIS-2 van start gegaan in Rome bij het CNR (Consiglio Nazionale delle Richerche). Het Italiaanse instituut leidt het consortium waarin vertegenwoordigers

Research takes you to strange places

/ March 23, 2015/ Atmospheric Physics and Chemistry, IMAU

According to the Promovendi Netwerk Nederland, 80% of all Dutch PhD students leave academic research after their graduation. I suppose that makes me part of a minority.  When I finished in 2012, I felt like I had only just begun to learn how research works in practice, and I wanted to keep applying what I had learned to scientific questions.

Promotie: Nieuwe methoden om de samenstelling en de processen van atmosferische organische stoffen in de gas fase en in fijnstof te onderzoeken

/ December 9, 2014/ Atmospheric Physics and Chemistry, IMAU

Joseph Timkovsky ontwikkelde nieuwe methoden om atmosferische organische stoffen in de gasfase en in fijnstof te onderzoeken. Vluchtige organische stoffen (VOS) en organisch fijnstof (OF) in onze atmosfeer beïnvloeden zowel onze gezondheid als het klimaat. Om de hoeveelheden VOS en OF in de atmosfeer te controleren, is het essentieel om hun belangrijkste bronnen en het effect van externe factoren op

Exciting prospects for the IMAU/SRON remote sensing group

/ November 25, 2014/ Atmospheric Physics and Chemistry, IMAU

On July 2nd, 2014, NASA brought the new Orbiting Carbon Observatory (OCO-2) satellite into orbit. This new instrument measures carbon dioxide (CO2) in the atmosphere and complements the Japanese Greenhouse Gas Observing Satellite (GOSAT), which since 2009 has been measuring the greenhouse gases CO2 and methane (CH4). Back then, the Japanese and American space agencies were in competition to launch
