Real-time monitoring, parametric profiling, and regulating contaminated outdoor air particulate matter throughout a region, via hyper-spectral imaging and analysis. Includes: (12) real-time sampling, and hyper-spectrally imaging and analyzing, contaminated outdoor air particulate matter, simultaneously at separate locations throughout the region, for generating local contaminated outdoor air particulate matter data-information packages; (14) real-time measuring outdoor weather-meteorological conditions, simultaneously at the locations, synchronized with the real-time sampling, imaging, and analyzing, for generating local outdoor weather-meteorological conditions data-information packages; (16, 18) real-time processing and analyzing the local data-information packages, for generating sets of local and regional geographical distribution parametric data-information profiles of contaminated outdoor air particulate matter, showing real-time local and regional geographical distributions of qualitative or/and quantitative parameters of contaminated outdoor air particulate matter, via a global data-information processing and communications unit. Particularly suitable for monitoring, profiling, maintaining, operating and controlling, developing, and planning, infrastructure and vehicular traffic, of human populated regions.
