  • Sonic Thermometry

    Sonic anemometers have had extensive use in the scientific community. These instruments are used to measure atmospheric parameters that most rotating instruments cannot. Wind speed and wind direction or individual axes of wind velocity are most commonly measured. Along with these measurements, another parameter can be extracted from the sonic anemometer (i.e.), sonic temperature. Since the ...

  • Water Vapor Interference in the UV Absorption Measurement of Atmospheric Ozone

    In this thesis work, a significant and sometimes large water vapor interference inherent to many and possibly all UV-based, commercially available ozone monitors was positively identified for the first time.  Depending upon the instrument's recent atmospheric history and calibration method, zone monitors can give erroneous results both immediately and hours later, and as a consequence possibly ...

  • The Boulder Atmospheric Observatory

    Abstract The Boulder Atmospheric Observatory (BAO) is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. The facility includes a 300 m tower instrumented with fast- and slow-response sensors, a variety of remote sensing systems, and a real-time processing and display capability that greatly reduces analysis time for ...

  • Proportional Counter vs SDD: Does XRF detector type matter?

    Typically, XRF analysers come with one of two types of detector: proportional counters or semiconductor-based detectors. Of the semiconductor devices, the silicon drift detector  – or SDD – is generally considered the best.   If your instrument has a proportional counter, you may be really happy with your analyser’s performance; for certain applications the prop ...

  • Energy and the protection of the atmosphere

    The essay reviews major environmental problems of energy development within a broader development and sustainability context. The role of energy in human development and major historical trends as well as their implications for carbon dioxide emissions are discussed. After summarising the scientific understanding of current and possible future climate change, the paper reviews available ...

  • Diurnal variation of the mixing-layer height and polonium concentration in the air

    The Mixing Height (MH) is one of the most important parameters that characterise the range of the atmospheric turbulence. This parameter shows characteristic diurnal variation but cannot be measured immediately. Therefore, it is evaluated indirectly by measuring other quantities. The measurement of radon concentration in the atmospheric air is one of the methods using natural occurring ...

  • CO2 Gas Hazards in the Brewing Industry

    The hazards associated with CO2 in the brewing industry are well known, yet people still die needlessly every year in tragic and completely avoidable accidents in breweries. Just last year in Germany, which has a good safety record, two workers died in separate incidents at the same brewery. In the first incident, the owner was found dead with his head and torso in a beer mixing tank. It is ...

  • Atmospheric chemical element pollution in an urban water-associated environment

    Nowadays, sustainability has become a complicated issue mainly in urban centres. Owing to the atmospheric emissions, the incorporation of toxic chemical elements is still not well known for urban water-associated ecosystems. Tillandsia bromeliads were employed as passive biomonitors of air pollution. Otherwise, the tank bromeliad Canistropsis billbergioides, native to the Atlantic Forest, was ...

  • 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 ...

  • Evaluation of atmospheric particle dispersion at a contaminated mine using biomonitors

    This study has carried out the assessment of magnitude of toxic elements contamination in and around the Sao Domingos mining area, a copper-sulphide open pit mine, and atmospheric transport of above elements by using lichens and Instrumental Neutron Activation Analysis (INAA). Samples of the epiphytic lichen Evernia prunastri and soils were collected. The concentrations of As, Sb, Fe and Zn were ...
