  • Atmospheric aerosol climate caution

    Carbon dioxide is not the only problem we must address if we are to understand and solve the problem of climate change. According to research published this month in the International Journal of Global Warming, we as yet do not understand adequately the role played by aerosols, clouds and their interaction and must take related processes into account before considering any large-scale ...

  • Scientists reject aerosol geoengineering

    Geoengineering schemes that could help some countries deal with global warming could have the opposite effect in others, according to a study. Geoengineering refers to large-scale interventions, such as capturing greenhouse gases, aimed at tackling global warming. Some climate scientists have suggested adding aerosols to the atmosphere to deflect the sun's rays in what they call 'solar radiation ...

  • Aerosols increasing over India

    Aerosols — particles or droplets suspended in the air that impact climate  by scattering or absorbing the sun’s radiation — are increasing across India, new research shows. The findings by S. Ramachandran and colleagues from the space and atmospheric sciences division of ...

  • Straightforward determination of anhydrosugars in aerosols

    Metrohm presents a new method for the sensitive and robust routine determination of the «smoke markers» levoglucosan, mannosan and galactosan in aerosols. The method couples ion chromatography with a highly sensitive pulsed amperometric detector (IC-PAD) and provides a simple and less expensive alternative to GC/MS. As such, it facilitates research into the effects of biomass burning aerosols on ...

  • Aerosols – their part in our rainfall

    “We have identified that the extensive pollution haze emanating from Asia may be re-shaping rainfall patterns in northern Australia but we wonder what impact natural and human-generated aerosols are having across the rest of the country,” Dr Rotstayn said. Aerosols are fine particles suspended in the atmosphere. Sources of human-generated aerosols include industry, motor vehicles and vegetation ...

  • Experts to study aerosols’ impact on Australia’s climate

    The impact that human-generated and natural atmospheric particles (aerosols) could be having on Australia’s climate will be discussed next week in Canberra at a workshop involving some of the world’s leading experts in the area. CSIRO Marine and Atmospheric Research scientist, Dr Leon Rotstayn, says the influence aerosols have on climate is still one of the ‘great unknowns’ in climate science. ...

  • Rainfall can release aerosols, study finds

    Original story at MIT News Ever notice an earthy smell in the air after a light rain? Now scientists at MIT believe they may have identified the mechanism that releases this aroma, as well as other aerosols, into the environment. Using high-speed cameras, the researchers observed that when a raindrop hits a porous ...

  • 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 ...

  • Dust Dominates Foreign Aerosol Imports To North America

    NASA and university scientists have made the first measurement-based estimate of the amount and composition of tiny airborne particles that arrive in the air over North America each year. With a 3-D view of the atmosphere now possible from satellites, the scientists calculated that dust, not pollution, is the main ingredient of ...

  • Outpacing climate change with atmospheric research collaboration

    Tiny particles in air called aerosols create smog, seed clouds, and control how much of the sun's heat makes it through the atmosphere. And yet these particles are the least understood aspect of climate research. Now, two research institutions are working together to tackle the role of aerosols in climate change -- specifically how aerosols from pollution, oceans and wildfires contribute to ...

  • TSI Introduces New AEROTRAK™ 9000 - Nanoparticle Aerosol Monitor

    The AEROTRAK 9000 is an industrial hygiene tool for measuring a new metric for nanoparticle aerosol exposure – lung deposited surface area. Surface area is the measurement metric that research has shown to be highly correlated with exposure and dosing of nanoparticle aerosols. It provides a simple and fast solution for indicating the surface area equivalent dose of particles in the size range of ...

  • 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 ...

  • Climate models may be overestimating the cooling effect of wildfire aerosols

    Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of ...

  • Real-time determination of anions and cations in aerosols by ion chromatography

    Research on air pollution requires rapid and accurate measurements of inorganic species in ambient air. Coupling a Particle-Into-Liquid-Sampler (PILS) to Metrohm’s 850 Professional IC allows for quasi-continuous measurements with an unprecedented temporal resolution of just 5 to 15 minutes.Filters are only second choice The determination of anions and cations in atmospheric aerosols yields ...

  • Climate studies to benefit from 12 years of satellite aerosol data

    Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. They are one of the greatest sources of uncertainty in climate change models. ESA's GlobAerosol project has been making the most of European satellite capabilities to monitor them. Using data from the Along Track Scanning Radiometer-2 on the ERS-2 satellite, ...

    India has launched an exhaustive study on the source, distribution and impact of soot released into its air — especially on climate and glaciers — that will help evidence-based policy-making. The five-year research agenda will involve about 250 scientists from institutes under the department of space, ministry of earth sciences and ministry of environment and forests at an estimated ...

  • New climate change research team established

    One of Australia's leading climate change modelling experts, CSIRO Wealth from Oceans Flagship’s Dr Wenju Cai, has been awarded a five-year CSIRO fellowship to establish a new research team examining climate influences on Australia. Dr Cai will build the team with funds provided through a 2011 CSIRO Office of the Chief Executive Science Leadership Award. CSIRO Chief ...

  • Climate research targets Western wildfire smoke

    Researchers are flying over Western wildfires to sample the thick smoke they emit and study its role in cloud formation and climate. The data-gathering campaign is intended to help scientists flesh out one of the least understood areas of climate: the role of aerosols, or particles given off by wildfires, and how they evolve over time. Biomass burning, such as forest fires and agricultural fires ...
