- Low-cost Prototype Pyrgeometer for Atmospheric Radiation Measurements Yuber Otálora-Porras Cristian Camilo Serrano-Franco César Alexander Chacón-Cardona Ingeniería emissivity black body irradiance pyrgeometer thermal radiation Objective: To design and build an instrument capable of measuring long-wave infrared radiation with elements of the national market that offers an excellent performance in measuring energy in this spectral band.Methodology: The best design was determined based on other existing instruments, innovating its development by using materials that are easily accessible in the country, and its operation was verified by characterizing an incandescent light bulb used as an infrared radiation pattern. Then, the radiation measured by the instrument was compared to that emitted by the source by means of an experimental setup that involved measuring the temperature at several distances.Results: A functional prototype was obtained, and its operation could be verified through a series of irradiance measurements according to the Stefan-Boltzmann law, through a calibration process with a known radiation source.Conclusions: A radiometric instrument for the thermal infrared band was designed and built. Raw materials and electronic components were used which were available in the local market, thus noticeably reducing the equipment’s production costs.Funding: This research was funded by the authors. 2022 artículo científico 0123-921X https://www.redalyc.org/articulo.oa?id=257073773006 https://www.redalyc.org/journal/2570/257073773006/ https://www.redalyc.org/journal/2570/257073773006/html/ https://www.redalyc.org/journal/2570/257073773006/257073773006.epub https://www.redalyc.org/journal/2570/257073773006/movil 10.14483/22487638.19157 en http://www.redalyc.org/revista.oa?id=2570 Tecnura application/pdf Universidad Distrital Francisco José de Caldas Tecnura (Colombia) Num.73 Vol.26
