Calibration of Solar Pyranometers for Accurate Solar Irradiance Measurements: A Data Set from the Pre- and Post-Calibration Process.

This study outlines the calibration of five solar pyranometers following ISO 9847 standards to improve the accuracy of solar irradiance measurements. The calibration process involved data collection, consistency checks, and calculations to determine calibration factors. Post-calibration results demonstrated reduced systematic errors and more accurate irradiance readings. The resulting data set reports on the entire calibration process, including pre- and post-calibration irradiance measurements, which enhances the reliability of solar energy measurements for future applications. The calibrated pyranometers were then used to measure vertical, horizontal, and ground-reflected solar irradiance, including diffuse radiation.本研究为提升太阳辐照度测量精度，依照ISO 9847标准（ISO 9847）对5台太阳总辐射表（solar pyranometer）开展校准工作。本次校准流程涵盖数据采集、一致性校验以及用于确定校准系数的相关计算步骤。校准后的结果显示，系统误差得到有效降低，辐照度读数的准确性显著提升。本数据集完整记录了全部校准流程，包含校准前后的辐照度测量数据，可进一步提升未来太阳能相关测量工作的可靠性。经校准的太阳总辐射表随后被用于测量垂直入射、水平入射以及地面反射的太阳辐照度，其中涵盖漫射辐射。
