通过亚洲水资源评估高分辨率观测数据集成（APHRODITE）项目的活动，收集和分析亚洲各地的雨量计观测数据，创建了一个涵盖57年以上的每日网格化降水数据集。APHRODITE的每日网格降水量是目前唯一的长期、大陆尺度、高分辨率的每日产品。该产品以5 000至12 000个站点收集的数据为基础，这些数据是通过全球电信系统网络提供的数据的2.3至4.5倍，用于大多数每日网格降水产品。因此，APHRODITE项目大大改善了对喜马拉雅山脉、东南亚和中东山区降水的区域分布和变化的描述。APHRODITE项目现在有助于确定亚洲季风降水变化、评价水资源、验证高分辨率模型模拟和卫星降水估计以及改进降水预报等研究。APHRODITE项目与亚洲国家开展外联活动，并与国家机构和世界数据中心进行交流。我们已经发布了开放获取的亚洲季风、中东和欧亚北方的APHRO_V1101数据集（分辨率为0.5° × 0.5°和0.25° × 0.25°）和日本的APHRO_JP_V1005数据集（分辨率为0.05° × 0.05°;见 www.chikyu.ac.jp/precip/ 和 http://aphrodite.suiri.tsukuba.ac.jp/ ).我们欢迎用户的合作和反馈。
A daily gridded precipitation dataset covering a period of more than 57 yr was created by collecting and analyzing rain gauge observation data across Asia through the activities of the Asian Precipitation—Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE) project. APHRODITE's daily gridded precipitation is presently the only long-term, continental-scale, high-resolution daily product. The product is based on data collected at 5,000–12,000 stations, which represent 2.3–4.5 times the data made available through the Global Telecommunication System network and is used for most daily gridded precipitation products. Hence, the APHRODITE project has substantially improved the depiction of the areal distribution and variability of precipitation around the Himalayas, Southeast Asia, and mountainous regions of the Middle East. The APHRODITE project now contributes to studies such as the determination of Asian monsoon precipitation change, evaluation of water resources, verification of high-resolution model simulations and satellite precipitation estimates, and improvement of precipitation forecasts. The APHRODITE project carries out outreach activities with Asian countries, and communicates with national institutions and world data centers. We have released open-access APHRO_V1101 datasets for monsoon Asia, the Middle East, and northern Eurasia (at 0.5° × 0.5° and 0.25° × 0.25° resolution) and the APHRO_JP_V1005 dataset for Japan (at 0.05° × 0.05° resolution; see www.chikyu.ac.jp/precip/ and http://aphrodite.suiri.tsukuba.ac.jp/ ). We welcome cooperation and feedback from users.
