Manual de calibración de piranómetros utilizando un pirheliómetro de referencia en base a la norma ISO 9846.

Abstract

The present endeavor entails the crafting of a calibration procedure manual for pyranometers using a reference pyrheliometer based on ISO 9846 standards. The standard suggests two calibration methods: the alternate sun-shadow method, and the continuous sun-shadow method. This work employs the continuous sun-shadow method, which necessitates the use of an additional reference pyranometer to measure diffuse solar radiation synchronized with the pyrheliometer measuring direct solar radiation. Subsequently, these data were collected and stored in an electronic data collection instrument (datalogger) in two different manners as stipulated by the standard, gathering data continuously every 5 seconds and on average every 30 seconds. Ultimately, the data were mathematically processed in accordance with the standard to determine the calibration factor and to compare the proposed data collection methods.
