PM 2,5 or fine particles, is a category of air pollutant composed of particles with an effective aerodynamic diameter equal to or less than 2.5 μm. These particles has been linked to human health effects as well as regional fog, visibility, and climate change issues. Due to cost and space restrictions, the US Environment The monitoring network of the Protection Agency is spatially sparse. To improve the layout monitoring resolution, previous studies have used satellite data to estimate the baseline PM concentrations, although these estimates are associated with moderate to large uncertainty when dealing with aerosol column size (aerosol optical depth) with surface measurements. For this purpose, we discuss low-cost air quality monitors (LCAQM) network is deployed in California. In this study, we present the LCAQM application and satellite data to measure the impact of forest fires in California during October 2017. The impact of fire on PM concentration 2,5 at various temporal (hourly, daily, and weekly) and spatial (local to the regional scale) has been evaluated. Comparison of cheap air quality sensors and reference grade air quality instruments show expected performance with moderate high uncertainty. Measurements of LCAQM, in the absence of federal equations data method, also found very useful in developing statistical models for changing the depth of the aerosol optics to PM 2.5 with PM-derived satellite performance 2.5 similar to that obtained using equivalent federal method data. This paper, too highlights the challenges associated with measuring LCAQM and PM-based satellite 2,5 which require further investigation and research.
