PLUMBER2: forcing and evaluation datasets for a model intercomparison project for land surface models.

PLUMBER2 is a model intercomparison project for land surface models. Multiple leading land surface and ecosystem models are evaluated for water and carbon fluxes at 170 flux tower sites, spanning multiple biomes and climate zones globally. The project is conducted within the Protocol for the Analysis of Land Surface Models (PALS) benchmarking system. This dataset provides the forcing and evaluation datasets underpinning PLUMBER2. The dataset is a collection of 170 flux tower sites globally for use in land surface modelling. It provides meteorological variables to force models and flux variables for evaluation. The original data were derived from the FLUXNET2015, La Thuile and OzFlux collections. The meteorological data have been gap-filled and quality controlled to be directly suitable in land surface modelling. The flux variables provide water, carbon and energy fluxes, including energy balance closure corrected latent and sensible heat fluxes. Addionally site metadata and leaf area index estimates from MODIS and Copernicus Global Land Service producst are provided. The final output is ALMA-formatted NetCDF files spanning the period 1992-2018, with individual site records ranging from 1 to 21 years.PLUMBER2是一项面向陆面模型（land surface models）的模型间比对项目。本项目依托全球范围内覆盖多种生物群区与气候带的170个通量塔站点，对多款主流陆面模型与生态系统模型的水、碳通量表现开展评估，且基于陆面模型分析协议（Protocol for the Analysis of Land Surface Models, PALS）的基准测试系统实施。本数据集为PLUMBER2项目提供核心的强迫场与评估数据集。 本数据集收录了全球170个通量塔站点的数据，专供陆面模型建模使用。数据集提供用于驱动模型的气象变量，以及用于模型评估的通量变量，其原始数据源自FLUXNET2015、La Thuile与OzFlux数据集合集。 气象数据已完成间隙填充与质量控制，可直接应用于陆面模型构建。通量变量涵盖水、碳与能量通量，其中包含经能量平衡闭合校正的潜热与感热通量。此外，数据集还提供站点元数据，以及来自MODIS与哥白尼全球陆地服务（Copernicus Global Land Service）产品的叶面积指数估算值。 最终输出结果为采用ALMA格式的NetCDF文件，时间跨度为1992年至2018年，单个站点的记录时长介于1至21年不等。
