VOC, Remote sensing, Microclimate, Pollution indoor-outdoor


VOCs (Volatile Organic Compound) influence indoor air quality, compromising human health and physical wellbeing. Outdoor air pollution adds indoor VOCs sources (building materials, cleaning, disinfecting and cosmetic products, smoking) and constitute complex mixtures of contaminated air. In this study, the indoor-outdoor evaluation of volatile organic compounds and formaldehyde will be considered. Ventilation, infiltration and intrusion processes produce a constant exchange between the outdoor air and the indoor air; thus, it is important to compare the results of confined environments with simultaneous outdoor air sampling. Furthermore, during such monitoring the microclimatic parameters will be measured in order to evaluate correlation between VOC concentration and meteorological conditions. Preliminary outdoor measurements show a clear correlation among relative humidity and HCHO concentration. At the same time the outdoor air data analysis, will be correlated with those available and acquired by the SENTINEL-5P satellites of the COPERNICUS constellation and AURA/OMI (Ozone monitoring Instrument) of NASA.
