The stations of the Air Pollution Monitoring and Forecasting Network (XVPCA) are distributed by: - To know the evolution of the levels of air quality in the time and in the territory. - Inform citizens of the state of air quality and its evolution. - Undertake sanitation actions if necessary. - Elaborate the maps of vulnerability and capacity of the territory - Comply with current regulations on the protection of the atmospheric environment. - Locate sources of pollutants. Stations have specific sampling equipment that takes samples to measure the concentration of certain contaminants. There are manuals, which are devices that allow a sample to be obtained and then analyzed in a laboratory. Pollutant concentration levels are not obtained in real time. In addition, the results inform us of average values ​​in a day and not of the peak values ​​that can be important and that are given in shorter periods of time. There are also automata (or analyzers), which analyze the sample continuously, ie pollution increases can be detected instantly and the results are sent directly to the data receiving center, which allows action very fast in case it is needed. Not all substances can be measured by automatic methods and often, these expensive procedures are not necessary. The generated data is stored on the station computer and transferred to the control center headquarters. In this station PM10, Metals, Benzene, B (a) p and NOx are analyzed manually
