1981-2020年全球海洋0.05度净辐射逐日数据

海表天均全波段净辐射(Rn)表征了海表可获取的能量。它与海洋热通量以及地球能量不平衡密切相关，在海洋和气候研究中具有重要意义。考虑到现有海表净辐射数据集的不足，一套0.05°的长时间序列（1981-2020）全球海表覆盖的天均海表净辐射产品应运而生。该产品利用全球分布的68个站点实测数据，两种遥感产品和四个再分析数据集融合得到。总体而言，该产品的评价结果较好(RMSD=23.56 Wm-2, bias=0.88 Wm-2, R2=0.878)，并且具有连续性，高空间分辨率，全球无缺失的特点，优于其他所有产品。Sea surface daily mean full-band net radiation (Rn) represents the energy available at the sea surface. It is closely correlated with marine heat flux and Earth's energy imbalance, and holds great significance in oceanographic and climatic research. Given the limitations of existing sea surface net radiation datasets, a daily mean sea surface net radiation product with 0.05° spatial resolution, long-time series (1981–2020), and global sea surface coverage has been developed. This product is generated by fusing in-situ measured data from 68 globally distributed stations, two remote sensing products, and four reanalysis datasets. Overall, this product exhibits good evaluation performance (RMSD=23.56 Wm⁻², bias=0.88 Wm⁻², R²=0.878), and features continuity, high spatial resolution, and global full coverage without missing data, outperforming all other existing products.
