  • Practical Aerosol Science - A short course in aerosol theory and measurement

    A 3-day course in practical aerosol science is being run between 8th and 10th June, at the University of Manchester. The course aims to deliver an introductory understanding of the challenges faced with aerosol measurements. Sampling ambient particles can be extremely challenging and answering a simple question like 'how big is the particle' depends on what instrument was used to ...

  • 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 ...

  • 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 ...

  • Impact of atmospheric particles on climate underestimated

    Levels of global secondary organic aerosol (SOA) in the Earth's atmosphere have increased by 60 per cent since pre-industrial times, according to new research, which suggests that the effects of SOA have been previously underestimated. This new information could help lead to better estimates of future climate change. SOA is made up of fine particles and droplets suspended in the atmosphere and 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 ...

  • 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, ...
