抽象。欧洲中期天气预报中心（ECMWF）最近推出的ERA 5再分析是一种分辨率更高的新再分析产品，将取代ERA-Interim，后者被认为是迄今为止格陵兰岛最好的再分析。然而，到目前为止，很少有人知道ERA 5的性能相比，ERA-Interim在格陵兰冰盖（GrIS）。本研究表明：（1）ERA 5没有显著改善ERA-Interim与GrIS近地面气候观测的比较;（2）与ERA 5相比，极地区域气候模式（例如MAR）仍然是研究GrIS气候的有用工具，特别是在夏季;（3）MAR结果对在其横向边界使用的强迫（ERA 5或ERA-Interim）不敏感。
Abstract. The ERA5 reanalysis, recently made available by the European Centre for Medium-Range Weather Forecasts (ECMWF), is a new reanalysis product at a higher resolution which will replace ERA-Interim, considered to be the best reanalysis over Greenland until now. However, so far very little is known about the performance of ERA5 when compared to ERA-Interim over the Greenland Ice Sheet (GrIS). This study shows (1) that ERA5 improves not significantly the ERA-Interim comparison with near-surface climate observations over GrIS, (2) polar regional climate models (e.g. MAR) are still a useful tool to study the GrIS climate compared to ERA5, in particular in summer, and (3) that MAR results are not sensitive to the forcing used at its lateral boundaries (ERA5 or ERA-Interim).
