CRUNCEP Version 7 - Atmospheric Forcing Data for the Community Land Model

The CRUNCEP is an atmospheric forcing dataset used forcing the land surface models. Specifically this dataset is designed to drive the Community Land Model over a long period. The CRUNCEP is a combination of two existing datasets; the CRU TS3.2 0.5 X 0.5 monthly data covering the period 1901 to 2002 and the NCEP reanalysis 2.5 X 2.5 degree 6-hourly data covering the period 1948 to 2016. The CRUNCEP dataset has been used to force CLM for studies of vegetation growth, evapotranspiration, and gross primary production and for the TRENDY (trends in net land-atmosphere carbon exchange over the period 1980-2010) project, among many other use cases. The CRUNCEP data archived in this dataset is Version 7.

CRUNCEP乃一气象强迫数据集，用于驱动地表模型。具体而言，此数据集旨在长时间驱动社区地表模型（Community Land Model）。CRUNCEP系由两个现有数据集结合而成；其一为CRU TS3.2 0.5 X 0.5月度数据，涵盖1901至2002年期间；其二为NCEP再分析2.5 X 2.5度6小时数据，涵盖1948至2016年期间。CRUNCEP数据集已被用于强迫CLM进行植被生长、蒸散量和总初级生产力的研究，并应用于TRENDY（1980-2010年期间净陆地-大气碳交换趋势）项目以及其他众多应用场景。本数据集中存档的CRUNCEP数据版本为7。
