Global, direct and diffuse spectral solar radiation at the Ito Campus of Kyushu University in 2021

Comprehensive, high-resolution dataset of global horizontal, diffuse, and direct solar radiation (SR) collected throughout 2021 in the midlatitude region of Fukuoka, Japan, using a high-precision spectroradiometer equipped with a rotating shadow band. The dataset provides a detailed understanding of variations in SR energy under all weather conditions and offers insights into dynamic light under natural conditions. Accompanying codes allow load data into matlab data, enabling the computation of plant-perceivable light signals, in terms of critical wavelength ratios. Consequently, the data set is ideal for further analysis with ecological data in the region, contributing to the refinement of plant-ecophysiological and ecological models in addition to SR predictions, SR modeling, understanding seasonal dynamics and climate change.

本数据集为2021年在日本福冈中纬度地区采集的高分辨率综合太阳辐射（solar radiation, SR）数据集，涵盖全球水平总辐射、散射辐射与直接辐射，采集设备为配备旋转阴影带的高精度光谱辐射计。本数据集可详细解析全天气条件下太阳辐射能量的变化特征，为理解自然环境下的动态光照提供研究视角。配套代码可将数据导入MATLAB，支持基于关键波长比计算植物可感知的光信号。因此，本数据集非常适合结合该区域生态数据开展后续研究，可助力优化植物生理生态与生态系统模型，同时可用于太阳辐射预测、辐射建模、季节动态解析以及气候变化研究。
