1 WATER DATA EXCHANGES ESIP Summer Meeting July 21, 2010 Nate Booth, USGS

2 THE USGS-USEPA WATER-QUALITY DATA EXCHANGE USGS: Nate Booth, Jon Scott, Dorrie Gellenbeck, Tom Kunicki, John Hollister, I-Lin Kuo, Jessica Thompson, Lorraine Murphy USEPA: Kristen Gunthardt, Kevin Christian

3 USGS NWIS & STORET Over Time 1999: Modern STORET** 2003: USGS / EPA Agreement 2007: Water- Quality Data Exchange 1960s: NWPCA (WATSTORE) NWIS* Legacy STORET** Data copied from NWIS to STORET 1972 EPA created * USGS National Water Information System ** USEPA Storage and Retrieval System

4 Water-Quality Data Exchange  Data format based on USEPA Water Quality Exchange (WQX) (NWQMC WQ Data Elements)  Common definitions and semantics  EPA’s Substance Registry System for chemicals  Chemical groups  Site types  Sampling media  Taxonomy  Common web services for serving Monitoring Locations and Water-Quality Results

5 Project Objectives 1) Common format and nomenclature 2) Web services to serve monitoring data 3) Services for users to find sites and data 4) Portal to merge disparate web service feeds ✓ ✓ ✓ = Phase One complete

6 WQX Web NWIS Aggregated weekly How it works – data flow

12  Further Integration  Common spatial frameworks (NHD, Aquifers)  Common analytical method metadata (NEMI)  Data cleanup  New Collaborations  NOAA IOOS  USDA  CUAHSI Future Work

13  Catalog of monitoring locations across agencies, organizations and scientific disciplines  Common spatial frameworks (NHD, Aquifers) and analytical method metadata (NEMI)  Development of an international water data transfer standard within OGC / WMO: WATERML2  American Committee on Water Information (ACWI) Future Work

14 Helping the World to Communicate Geographically Hydrology Domain Working Group A joint working group of the OGC and WMO constituted as an OGC Domain Working Group. Brings together interested parties to develop and promote the technology for greatly improving the way in which water information is described and shared. Co-chaired by representatives nominated by the OGC TC and the World Meteorological Organisation’s (WMO) Commission for Hydrology (CHy). Current Co-Chairs: Ilya Zaslavsky (SDSC), Ulrich Looser (GRDC) and David Lemon (CSIRO) > 50 Participants, > 30 Organisations Courtesy: David Lemon, CSIRO

15 Helping the World to Communicate Geographically © 2009 Open Geospatial Consortium, Inc. 15 Expected Outcomes An agreed feature model (ie. what are the features of the hydrosphere (from an information perspective) and how are they related.) An agreed observation model. Agreed vocabularies, endorsed by the community, and by WMO in particular. Agreeing on semantics is a long process, but we should be able to recommend some vocabularies Also: services carrying the above

16 Groundwater Data Exchange – OGC/WMO HydroWG Interoperability Experiment  Test and enhance OGC standards for water observations  Exchange groundwater well characteristics and water levels with Canada  Next steps: streamflow, water-quality

17 National Groundwater Monitoring Network  American Committee on Water Information Subcommittee on Groundwater  Pilot portal under development for 6 states:  MT, MN, TX, IL, IN, NJ  Built on open standards and leverages interoperability experiment within HydroWG

18 Pilot Data Portal - Status

21 THE GEO DATA PORTAL Nate Booth, Lauren Hay, Rich Signell, Tom Kunicki, Roland Viger, Steve Markstrom, Ivan Suftin, Dave Blodgett, Ryan Zoerb

22 Geo Data Portal

23 Common Data Model (NetCDF- Java) Point Timeseries (NetCDF-CF SOS, JDBC) -GCMs to climate stations -Streamflow, Buoys Grid static (OpenDAP, WCS) -DEM, Soils, Landcover Grid Timeseries (OpenDAP) -GCMs -Meteorological Observations Geoprocessing Web Service Retrieve, Subset Aggregate, summarize Geo Data Portal Formatted model input. Modeling extent(s) -BBOX, Shpfile, GML

24 Meteorological Global Summary of Day Station Data River Forecasting Center's Radar-Rain Gage-PRISM 4km Gridded Rainfall North American Regional Reanalysis 32km Gridded Data 12km Gridded Meteorological Observations from Climate Change Community National Solar Radiation Database PRISM Parameter-Elevation Regression on independent Slopes Model Downscaled climate models Land National Land Cover Dataset 10m National Elevation Dataset SSURGO Polygons with Horizons for Lake Michigan Vertically Averaged SSURGO on a 10m National Grid Global Shuttle Radar Topography Great Lakes Nowcast (NOAA GLERL) Datasets
