Gap filled GEBA data

Global (diffuse and direct) shortwave downwelling radiation at the surface between year 1961 and 2014. A total of ~1400 ground stations from GEBA archive has been selected and been through the machine learning technique "random forests" (Breiman, 2001) to fill gaps in from original GEBA dataset. A report on the gap filling process can be attained by e-mailing Trude Storelvmo ([e-mail]).本数据集包含1961年至2014年间地表接收的全球（漫射与直射）短波下行辐射数据。研究从GEBA档案库中选取了约1400个地面观测站的观测资料，并采用机器学习技术"随机森林（random forests，Breiman, 2001）"对原始GEBA数据集中的缺失值进行填补。有关该缺失值填补流程的详细报告，可通过发送邮件至Trude Storelvmo（[e-mail]）获取。
