ABSTRACT

GEOSS Water Services: Federating Regional and National Water Data

David Arctur, University of Texas at Austin

Since 2012, the Water SBA team for the GEOSS Architecture Implementation Pilot (AIP) has helped water data agencies in several countries to implement and publish standards-based water resource information. The following water data providers and research centers have developed a consistent implementation of this framework, which are or will soon be searchable in GEOSS:

• CUAHSI Water Data Center - collecting water data from over a hundred data providers
• Canadian Rainfall Monitoring Network - precipitation
• Flemish Water Portal (Belgium) - streamflow
• French Geological Survey (BRGM) Groundwater Level Monitoring Network
• Italian National Water Agency (ISPRA) - streamflow
• New Zealand National Water Agency (NIWA) - streamflow, temperature, and 9 water quality variables
• Taiwan Monitoring Network - streamflow
• USGS National Water Information System (NWIS) - streamflow
• NASA Land Data Assimilation System (LDAS) - model-based time series (“data rods”) for global precipitation, runoff, soil moisture, evapotranspiration, and other land surface dynamics variables.

Continued development and expansion of this network will bring within reach the ability to study and understand water data across and among whole continents, on demand.

The emphasis in the upcoming 2015 cycle will be the application of this GEOSS Water Services framework for flood monitoring, prediction, and mitigation.
