An humidity sensor developed by the Physikalisch-Technische Bundesanstalt (PTB), the SEALDH laser hygrometer, has proven its worth when used aboard an aircraft; it fulfils all pre-conditions to be used as a transfer standard for conventional humidity-measuring instruments. This would allow the quality of air humidity measurements in the Earth's atmosphere - and, thus, also climate model computations - to be improved. http://phys.org/news281607464.html Space & Earth Mon, 04 Mar 2013 08:50:03 EST news281607464 Scientists have developed a new approach for evaluating past climate sensitivity data to help improve comparison with estimates of long-term climate projections developed by the Intergovernmental Panel on Climate Change (IPCC). http://phys.org/news273327347.html Space & Earth Wed, 28 Nov 2012 13:00:07 EST news273327347 Atmospheric aerosol particles have a significant effect on climate. An international team of researchers has now discovered that a chemical process in the atmosphere called aging determines to a major extent the concentration and the characteristics of aerosol particles. To date, this aspect has not been accounted for in regional and global climate models. In the Muchachas [Multiple Chamber Aerosol Chemical Aging Experiments] project, the team has not only managed to demonstrate the effects of aging but has also been able to measure these. Their findings have been published in the specialist journal Proceedings of the National Academy of Sciences (PNAS). http://phys.org/news268652117.html Space & Earth Fri, 05 Oct 2012 10:35:27 EST news268652117 Powerful fires currently scorching parts of Russia and Africa sent up plumes of smoke into the atmosphere, images captured on Aug. 2, 2012, by the nation's newest Earth-observing satellite, Suomi National Polar-orbiting Partnership (NPP). http://phys.org/news265447888.html Space & Earth Wed, 29 Aug 2012 09:00:05 EST news265447888 (PhysOrg.com) -- Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colo., released a study claiming that inconsistencies between satellite observations of Earth's heat and measurements of ocean heating amounted to evidence of "missing energy" in the planet's system. http://phys.org/news247125584.html Space & Earth Mon, 30 Jan 2012 06:00:12 EST news247125584 Scientists have developed important new insight into the sensitivity of global temperature to changes in the Earth's radiation balance over the last half million years. http://phys.org/news242394400.html Space & Earth Tue, 06 Dec 2011 11:46:51 EST news242394400 A new paper published in Philosophical Transactions of the Royal Society A, explains weaknesses in our understanding of climate change and how we can fix them. These issues mean predictions vary wildly about how quickly temperatures will rise. This has serious implications for long term political and economic planning. The paper's lead author is Dr Nigel Fox of The National Physical Laboratory, The UK's National Measurement Institution. http://phys.org/news235647700.html Space & Earth Mon, 19 Sep 2011 10:42:00 EST news235647700 The Antarctic system comprises of the continent itself, Antarctica, and the ocean surrounding it, the Southern Ocean. In a study for a doctoral degree by geophysicist Kai Rasmus, University of Helsinki, Finland, measurements were made during three Austral summers to study the optical properties of the Antarctic system and to produce radiation information for additional modeling studies. http://phys.org/news177597461.html Space & Earth Mon, 16 Nov 2009 12:38:39 EST news177597461
