1981-2018年全球0.05度大气层顶反射太阳辐射逐月数据

本项目基于AVHRR日均大气层顶反射太阳辐射，通过平均得到月均大气层顶反射太阳辐射，空间分辨率0.05度，时间范围1981-2018。目前已有的大气层顶反射太阳辐射产品大多存在空间分辨率粗、空间覆盖范围有限或时间覆盖短的问题，这些问题都限制了全球尺度气候变化的研究。因此，发展长时间序列高空间分辨率的大气层顶反射太阳辐射的遥感反演算法十分必要。本项目通过将反照率与入射太阳辐射相乘得到该数据集。

This project is based on the daily mean top-of-atmosphere reflected solar radiation from AVHRR, and derives monthly mean top-of-atmosphere reflected solar radiation via averaging. The dataset has a spatial resolution of 0.05 degrees and covers the period from 1981 to 2018.
Most existing top-of-atmosphere reflected solar radiation products suffer from issues including coarse spatial resolution, limited spatial coverage, or short temporal coverage, all of which restrict research on global-scale climate change. Therefore, it is highly necessary to develop remote sensing retrieval algorithms for long-time-series and high-spatial-resolution top-of-atmosphere reflected solar radiation. This dataset is generated by multiplying albedo with incident solar radiation in this project.
