This study demonstrates spatial mapping of outdoor air contaminants using remote sensing FTIR. The technique effectively visualizes chloroform and methanol concentrations, aiding industrial emission monitoring and pollutant distribution analysis.

Area of Science:

  • Environmental Science
  • Remote Sensing
  • Analytical Chemistry

Background:

  • Accurate spatial mapping of air contaminants is crucial for environmental monitoring.
  • Remote sensing techniques offer non-invasive methods for atmospheric analysis.
  • Understanding pollutant dispersion patterns aids in mitigating industrial emissions.

Purpose of the Study:

  • To develop and validate a spatial mapping method for outdoor air contaminants using remote sensing Fourier-transform infrared (FTIR) spectroscopy.
  • To compare the spatial distribution of chloroform and methanol using this technique.
  • To assess the utility of spatial mapping for identifying industrial emission sources and pollutant flow.

Main Methods:

  • A quasi-steady-state experiment was conducted with freely dispersed chloroform and methanol.

  • Remote sensing FTIR was employed to measure Path-Integrated Concentrations (PIC) in various optical paths.
  • Kriging and two-dimensional contour mapping techniques were used to visualize contaminant concentrations.

    • Main Results:

    • Simultaneous PIC data for chloroform and methanol were obtained.
    • Kriged maps and contour maps showed consistent concentration peak positions.
    • The kriged map for chloroform exhibited a sharper peak compared to methanol, despite overall low concentrations.

    Conclusions:

    • Spatial mapping of air contaminant concentrations using remote sensing FTIR is feasible and effective.
    • The method provides valuable insights into the location of industrial emission peaks.
    • This approach enhances estimates of pollutant flow and distribution, supporting environmental monitoring and protection efforts.
