Resumen

In the last decade, the air pollution networks are increasing in the main countries, however, the installation of low-cost or robust sensors have challenges associated to the geography installation and the proximity differences specially with buildings or mountains. Therefore, a calibration of the satellite with the air pollution sensor and networks should be a solution for the implementation in large scale in our countries. In this paper, it proposes a new methodology for the calibration of the satellite sensors and the low-cost sensor network installed in Lima with ten sensors. Therefore, the satellite data allows to evaluation all the city with 624′726′826′182 points, though pixel of 5m2, in each PM2.5 in Lima; our findings are a mean absolute error of 0.22 μg/m3 in a scale of 0 to 80μg/m3.
