The global water resources and use model WaterGAP v2.2e - daily water storage model output driven by gswp3-w5e5 and historical setup of direct human impacts

Assessing global freshwater resources and human water use is of value for a number of needs but challenging. The global water use and water availability model WaterGAP has been in development since 1996 and has served a range of applications such as assessments of global water resources and water stress, also under the impact of climate change, drought hazard quantification, Life Cycle Assessments, water (over)use and consequently depletion of water resources and a better understanding of terrestrial water storage variations (jointly with satellite observations). Here, the reader can download daily model output for water storage variables for the time period 1901-2019 (2023) that was computed by driving WaterGAP v2.2e by two alternative climate datasets (climate forcings) that were generated in the ISIMIP context (https://www.isimip.org) and are described in https://data.isimip.org/10.48364/ISIMIP.982724. In the paper connected to this dataset (in review with Geoscientific Model Development), the newest model version, WaterGAP v2.2e is described by providing the modifications to the previous version v2.2d (Müller Schmied et al. 2021) and the corresponding changes in model output. Here, the single water storage compartments and terrestrial (total) water storage are provided.

评估全球淡水资源与人类用水状况，虽具备多方面应用价值，但同时极具挑战性。全球用水与水资源可利用量模型WaterGAP自1996年起便投入开发，已被广泛应用于诸多研究场景：涵盖全球水资源与水资源压力评估（含气候变化影响下的评估）、干旱灾害量化、生命周期评估（Life Cycle Assessments）、水资源过度使用及由此引发的水资源耗竭研究，以及结合卫星观测数据深化对陆地水储量变化的理解。
本数据集提供了1901-2019（2023）时段内的水储量变量逐日模型输出结果，该结果通过两套在ISIMIP框架下生成的可选气候数据集（气候强迫场，climate forcings）驱动WaterGAP v2.2e模型计算得到，相关气候数据集的详细说明可参见https://www.isimip.org与https://data.isimip.org/10.48364/ISIMIP.982724。
与本数据集配套的论文目前正在《地球科学模型开发（Geoscientific Model Development）》期刊审稿中，该论文对最新版本WaterGAP v2.2e进行了详细介绍：包括相较于旧版本v2.2d（Müller Schmied等人，2021）所做的改进，以及模型输出的相应变化。
本数据集提供了单个水储量分区以及陆地（总）水储量数据。
