The Consortium of Universities for the Advancement of Hydrologic Science (CUAHSI) is an organization aimed at developing infrastructure and services for the advancement of hydrologic science and education in the United States. A key development of CUAHSI is WaterOneFlow web services, which provide programmatic access to hydrologic data from a variety of data sources in a consistent manner, regardless of the data source. Weather Downloader is a Geographic Information System (GIS) application that uses WaterOneFlow web services to download the time series data needed to describe the hydrology of a given geographical area. It runs within ESRI's ArcGIS environment and can access meteorological, groundwater and streamflow data from public repositories such as USGS and Daymet. In addition, it can be easily customized to access any source of data that have been published using the WaterOneFlow web service protocol. Weather Downloader interacts directly with ESRI's feature classes by systematically processing individual features and retrieving associated data into the TimeSeries table of an Arc Hydro data model (Maidment, 2002). Through the Arc Hydro data model, time series data can be integrated with spatial data and made accessible to GIS-based hydrologic and hydraulic simulation models.
