Apoyo a las actividades técnicas que se adelantan en el marco de la operación del Sistema de Vigilancia de Calidad del Aire de la Universidad Distrital - SVCAUD

Abstract

The Universidad Distrital F.J.C. has an air quality laboratory on its property, which serves the academic community in the formulation of research projects associated with problems and phenomena presented by the air component in the city of Bogota. For this purpose, the laboratory has high-tech equipment for the measurement, monitoring and modeling of the different pollutants and meteorological variables to be assessed, such as PM 10 or PM 2.5, temperature and precipitation, respectively. To learn about the behavior of pollutants in the city of Bogotá, the air quality laboratory of the Universidad Distrital has an Air Quality Monitoring System. This system is made up of 3 stations located at the different university sites. Once the necessary information on the different pollutants and meteorological variables is collected through the monitoring equipment, this information is reported to a server that has a software capable of handling data and providing reports according to what is required, with the purpose of publishing valid and understandable information on the evolution of the different pollutants and meteorological variables present in the environment of Bogota. Therefore, the development of SVCAUD contributes to the knowledge and the proposal of solutions to the city's atmospheric problems, derived from the information obtained and managed by the system. However, today the Air Quality Monitoring System of the Universidad Distrital, considered as a communicative instrument for the academic community, requires a structural update in its monthly reports, which allows its readers an easy understanding of the information. For this purpose, the reports require a simple description of the equipment and pollutants monitored. Additionally, software is used that allows the selection and adequate implementation of tools contained in the same program to analyze data at convenience, where the objective is to synthesize the collected data into useful and easy-to-understand information. This is consolidated in the preparation and updating of monthly reports. Seen in another way, the information provided in the documents is, roughly speaking, an analysis that seeks to historically correlate such information based on the behavior of the pollutants monitored by SVCAUD. Based on the previous paragraph, the use of programs such as Rstudio, in question for the study, requires libraries and commands (scrip) capable of reading the information provided for the creation of figures and graphs. Example of this, the concentrations of PM10 and PM2.5 monitored in the month of September 2023 and in which are evaluated under national and international regulations, where the days of exceedance are considered under the criteria of the standard adopted by the system itself. From there, the information obtained from the software is implemented in the new structuring of the report or monthly report, along with other descriptions and figures that make the office a robust document based on information related to air quality in the city of Bogota.
