  • Combined use of space–borne observations of NO2 and regional CTM model for air quality monitoring in Northern Italy

    In this paper SCIAMACHY observations of earth radiance are used to retrieve nitrogen dioxide (NO2) tropospheric column by DOAS spectrometric technique and radiative transfer modelling for AMF computation. These satellite column measurements are then merged with TCAM model simulations, to improve the model output at the ground level. The method used is a weighted rescaling of ...

  • Poisoned at the Arena

    Canadians love their hockey. With that in mind, a reasonably sized community will have an ice rink. Global Maritimes states in a news article that “there are 10 times as many rinks in Canada as there are in the United States.” That means more ice resurfacers, also known as zambonis, and ice edgers can be found in Canada than the USA. An ice resurfacer is a machine that is used to ...

  • BLUE LIGHT CONVERTER SIGNALS WAY FORWARD FOR NO2 MEASUREMENT

    Local authorities seeking more accurate NO2 readings should consider using analysers which incorporate ‘Blue Light Converters’ says air quality monitoring specialists Enviro Technology.   This comment comes following a presentation held at the Royal Society of Chemistry / AAMG Conference in December 2010 by EMPA (Switzerland) – an independent research and services ...

  • An experimental method to estimate the temperature of individual nanowires

    In this paper, the authors present an effective experimental method to estimate the temperature of individual metal oxide nanowires that can be used to quantify the heating produced in conductometric or other operating conditions. The here-proposed method is based on the analysis of the recovery time of the nanowire's resistance after exposure to a gas pulse (0.5 ppm of NO2 in dry air). It is ...

  • Seasonal evolutions of ozone (O3) and its nitrogen precursors (NO, NO2) in urban Sfax (Tunisia)

    Seasonal evolution of ozone (O3) and its nitrogen precursors (NO, NO2) in downtown Sfax (Tunisia) was monitored. Nitrogen oxides are shown to be closely related to local vehicle sources. Seasonal ozone levels, however, are shown to be dependent on regional meteorological conditions. High ozone levels are due to the effect of anticyclones and stratosphere intrusions (cut-off lows). Low levels are ...
