In recent decades, the city of Lima has increased its level of environmental pollution with human development, with an average annual concentration of 28.0 µg⁄𝑚3 with respect to Particulate Matter less than 2.5 microns (𝑃𝑀2.5, as of now) for 2018, positioning it as the eighth most polluted city in Latin America and 22nd worldwide. In the present investigation, satellite information is evaluated for the study of air quality data obtained incorporating climatic conditions in the province of Lima, Peru. The sources of satellite information were obtained from the Visible Infrared Imaging Radiometer Suite (VIIRS, from now on) sensor on board the Suomi NPP satellite; and from the Moderate Resolution Imaging Spectroradiometer (MODIS, from now on) sensor on board the AQUA and TERRA satellites. Another source of information was the National Service of Meteorology and Hydrology of Peru (SENAMHI, from now on), which has ten stations distributed in the districts of the province of Lima and from which air quality data were obtained. These stations have automatic measuring instruments for meteorology (pressure, relative humidity, wind speed and direction) and air quality, whose data were included and projected on climate data in the present study to evaluate if they present any similar trend with the trends evaluated for satellite product data. The analysis of Particulate Matter data that are smaller than 10 microns (𝑃𝑀10), 𝑃𝑀2.5, Temperature, Relative Humidity and Wind Speed from the air quality stations was established; likewise, for the case of satellite products, the Aerosol Optical Depth (AOD, from now on) data obtained from algorithms of the different instruments on board the mentioned satellites were analyzed. Finally, in order to know ranges in the different air quality stations, extreme values of Particulate Matter (PM) were determined for the domains to which the statistical methods are applied. This elaboration of maximum and minimum graphs is done to know if the air quality data are in an established range, or if there is any range that is out of the normal and which may be due to special weather conditions, lack of maintenance at the stations or any other factor. Likewise, trend analysis was performed on the best domains found in the databases, both from satellite data and data obtained from the air quality stations, applying the statistical methods of Sen's Slope and Mann Kendall Test. The Probability Density Function (PDF) was also applied to the broad domains of the databases obtained to identify regions of higher and lower probabilities for values of a variable, as well as the projection of satellite information with respect to climate variables, in order to know the curve corresponding to each parameter.
