  • Aerial Radiation Detection

    In this time of multiple threats to our security: dirty bomb; cyber; shooters in public places; homemade bombs; misinformation; etc. we feel extremely vulnerable; perhaps more vulnerable than ever before. With the advent of Drone technology now available to private citizens, technology previously only held by the military, the opportunity has come to marry Drone Technology with aerial sensors. ...

  • Sahara Dust pollutes Southern Greece – this is how Lufft Ceilometers can help

    Information related to the range resolved aerosol-cloud physical properties appears to be mandatory for our better understanding of the atmospheric dynamics, air quality and climate change. Recently, the Southern part of Greece  suffered from a severe Saharan Dust outbreak. The dust had been driven across the Mediterranean due to strong south winds. The island of Crete was mostly affected by ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • Observational needs for four-dimensional air quality characterization

    Surface-based monitoring programs provide the foundation for associating air pollution and causal effects in human health studies, and they support the development of air quality standards and the preparation of emission reduction strategies. While surface-oriented networks remain a key tool for addressing traditional single pollutant human exposure challenges, these networks in isolation are not ...

  • Relief for Allergy Sufferers: AQM Stations from Plair Visualize Pollen

    The prevalence of pollen allergy is vast, attaining 25-30% of the population worldwide, and this number continues to grow. Symptoms include rhino-conjunctivitis, asthma and eczema. Plair’s Rapid-E system powered with artificial intelligence provides real-time pollen measurements together with other particle present in the air to ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Micro Pulse LiDAR Enhances Global Aviation Safety - Case Study

    Monitoring Volcanic Ash provides early warnings of Hazardous Atmospheric Conditions Volcanic ash is a recurring impediment to normal air-traffic operations in Europe, Asia and South America due to potential jet engine damage caused by the razor-sharp particles in dense ash plumes. A notable example is the 2010 eruption of the Eyjafjallajökull volcano in Iceland that shut-down air ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • Tracking Air Pollution with Mini Micro Pulse LiDAR - Case Study

    Portable Monitoring Solution Offers Valuable Insight Into Haze Problem Poor air quality in large urban population centers has a negative impact on health and quality of life. To address these issues, the Institute of Urban Meteorology (IUM) in Beijing, China, is conducting fundamental research to better understand, forecast and mitigate atmospheric haze, i.e., air pollution. Over the past ...

  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...
