The Watershed Allied Telemetry Experimental Research(WATER) is a simultaneous airborne, satellite-borne, and ground-based remote sensing experiment aiming to improve the observability, understanding, and predictability of hydrological and related ecological processes at a catchment scale. After the experiment, the efforts have been made to process the data and improve the data quality. A data and information system(WATER-DIS) are also required to develop to manage these data. Two data service centers have been built up in Cold and Arid Regions of Environmental and Engineering Research Institute, Chinese Academy of Sciences(http://westdc.westgis.ac.cn/water) and Beijing Normal University(http://rsdc.bnu.edu.cn/).The WATER-DIS is a metadata-driven system. This research introduces the architecture, database and function of WATER-DIS and makes a summary table of the released data of WATER. According to the statistics, about 2.5 TB data are released including the ground data, meteorological and hydrological data, airborne remote sensing data, and satellite-borne remote sensing data.
