  • New approach improves accuracy of aerosol measurements on cloudy days

    Satellites taking atmospheric measurements might now be able to see blue skies as clearly as optimists do. Researchers have found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases. The result might lead to more accurate estimates of the amount of sunlight penetrating the atmosphere. Because clouds represent one of the ...

  • Palas to expand product range for discharge systems for aerosol conditioning

    X-ray neutralizer XRC 049 Electrically charged aerosols can seriously distort measurement results, e.g. in filter testing. Discharge systems produce a balanced and reproducible charge distribution in the aerosol and thus enable reliable measurement data. With the new XRC 049, Palas offers a discharge system that is particularly suitable for mobile measurements. The X-ray neutralizer is ...

  • Monitoring how aerosols affect climate change

    Monitoring aerosols is of growing interest especially as current research has indicated that fine particulates are linked to not only adverse health effects but also climate change. It has been known for some time that fine particulate matter (PM2.5) has been widely linked to adverse health effects such as asthma. Approximately 70% of particulate mass generated by, for example, bush fires is less ...

  • Measurement makes the difference at Cascade Technologies

    The National Physical Laboratory (NPL) has worked with Cascade Technologies at various stages of its development and growth, from its formation as a spin-out from the University of Strathclyde in 2003 to its current position as an award-winning SME and the only commercial supplier of quantum cascade lasers for identifying and measuring industrial gases. Two of the company's ...

  • An instrument from Environnement S.A will measure volcano ashes

    In partnership with the environment and space physics and chemistry laboratory at orleans and CNES (National Space Research Centre), we have started the development ofa ‘LOAC’ measurement system, that will count and size grade aerosols, for balloon-carried stratospheric measurement applications. The first flight of the LOAC was organised by the CNES, from the ESRANGE/Kiruna base ...

  • A cloud sensor measuring more than just clouds: The CHM 15k

    Atmospheric and non-atmospheric parameters in the air space challenge researchers, weather services and airports. Although these applications pursue different targets, there’s one sensor system, satisfying all of those users: the CHM 15k. It scans the atmosphere in heights of up to 15 km and detects clouds, ...

  • New particulate measurement technology enables climate change ‘quick hit’

    More accurate measurement of Black Carbon particles is now within reach of UK local authorities, air quality and climate change researchers and industry thanks to a highly-specified device, newly available via Enviro Technology.   Reducing levels of Black Carbon in the air improves human health and slows climate change. Because it is dark, Black Carbon absorbs a lot of heat from the sun and ...
