The National Solar Radiation Database (NSRDB) offers satellite-derived irradiance over most of the Americas. The latest version of the NSRDB hosts broadband irradiance estimates at 5-min–2-km resolution, which have improved from the previous 30-min–4-km resolution. Whereas this new dataset is expected to continue providing invaluable solar resource information to researchers and practitioners worldwide, its accuracy needs to be validated. Validating high-resolution data must go beyond reporting the overall error metrics. To that end, time series features are used here to study the correspondence between the satellite-derived and measured irradiance transients. This paper also provides an in-depth discussion on the data quality issues observed during the validation.

从国家太阳辐射数据库（NSRDB）验证5分钟辐照度

国家太阳辐射数据库（NSRDB）提供了美洲大部分地区的卫星辐射。NSRDB的最新版本以5分钟2公里的分辨率托管宽带辐照度估计值，该分辨率比以前的30分钟4公里的分辨率有所提高。预计该新数据集将继续为全球研究人员和从业人员提供宝贵的太阳能资源信息，但其准确性需要得到验证。验证高分辨率数据必须超出报告总体错误指标的范围。为此，在这里使用时间序列特征来研究源自卫星的辐射和测得的辐射瞬态之间的对应关系。本文还对验证期间观察到的数据质量问题进行了深入讨论。
