| Popis: | The paper performed regression analysis to calculate the correlation model between the PM10 values in ground measurement data by DustTrak II and atmospheric reflections obtained from satellite image processing VNREDSat-1. The obtained results evaluate the ability to identify and support the monitoring PM10 dust in the air from VNREDSat-1 satellite image data based on the correlation coefficient (R 2 = 0.943) and Root Mean Square Error (RMSE = 52 µm/m3 ). The experimental area is along the roads of Hanoi city, where there is high traffic density, many roads are under construction and high air pollution. |
