IV.  FEATURE: The Delaware Environmental Observing System (DEOS)

The Delaware Environmental Observing System (DEOS) is a real-time system dedicated to monitoring environmental conditions across the State of Delaware, the near-shore coastal waters and the Delaware Bay, and adjacent regions in Maryland, Pennsylvania, and New Jersey.  Although DEOS is designed, in part, to be a source for real-time and archived environmental data, it specifically serves as a tool for decision makers involved in emergency management, natural resource monitoring, agriculture, transportation, and other activities throughout the State of Delaware and the Delmarva Peninsula.  It is a cooperative venture supported by a number of state and federal agencies and many of its visualization and analysis tools are designed to be adaptable outside Delmarva.  Through the combined efforts of the State of Delaware, the Delaware Emergency Management Agency (DEMA), the Delaware Department of Natural Resources and Environmental Control (DNREC), and the University of Delaware (UD), DEOS has now secured long-term support that will keep us going to accomplish our mission.


The DEOS Environmental Monitoring and Observing Network (DEMON) combines several environmental data networks.  These include weather stations installed and maintained by DEOS as well as USGS and DGS stream and tide gage data, ocean and near-shore buoy data from NOAA’s National Data Buoy Center, and weather station networks from UD’s Research and Education Center in Georgetown (UD’s College of Agriculture and Natural Resources), the National Weather Service (NWS), Delaware’s National Estuarine Research Reserve, Delaware Department of Transportation’s road weather sensors, the Delaware Solid Waste Authority, and Christiana Care.  DEOS has installed fourteen weather stations around the region (4 in New Castle County, 2 in Kent County, 5 in Sussex County, 1 in Cecil County, and 2 in Chester County) and there are plans to install five to seven more stations along the Delaware Coast and seven more stations in Chester County, MD (in cooperation with Chester County EMS) in the next year.  Weather data are received every five minutes from most data networks (for a total of 22 stations in the five counties) and stream and tide data are received with a fifteen minute resolution.  Observations include both meteorological (e.g., air temperature, atmospheric pressure, humidity, precipitation, soil moisture and temperature, solar radiation, and wind vector) and hydrological variables (e.g., streamflow, tidal heights, wave height and period).  Information on air and water quality as well as well levels will be incorporated soon.  A significant effort is currently directed toward providing quality control and assurance (QA/QC) and preventive maintenance.


The DEOS Integrated Visualization and Analysis System (DIVAS) will integrate surface weather observations with NWS WSR-88D radar precipitation estimates using ESRI’s ArcGIS 9 Server.  DIVAS will provide estimates of meteorological and environmental variables over a high spatial resolution grid which can be input to a variety of agricultural or other numerical models or viewed over the Internet. This application is quite innovative and both Kentucky and Virginia are currently using the prototype DIVAS system to monitor drought and other environmental conditions across their respective states.  DEOS Analysis Systems (DAS) will provide easy access to data stored in an Oracle database, allowing informed decision making for a variety of environmentally sensitive applications.  In particular, the DIVAS system can notify emergency management or other state or local personnel of developing conditions, such as high streamflow or tide levels, heavy rainfall (measured by gage or estimated by radar), or extreme heat or cold stress (apparent temperature or wind chill).  Such notification is made on a selective basis so that decision makers are only notified of conditions in their area.  Data are provided in real-time to a number of state and federal agencies, including the National Weather Service.


However, DEOS provides more than data acquisition and dissemination.  To date, DEOS has proven useful in a number of environmental applications.  During the passage of tropical storms, nor’easters, or heavy snowfall, DEOS staff works with DEMA to provide up-to-date information on developing weather events.  DEMA also uses DEOS data to assist with developing emergency management situations, such as toxic spills, hazardous chemical releases, and flash flooding events.  DNREC regularly uses DEOS data to provide information for pesticide management, mosquito control, and to schedule controlled burns of invasive plant species along the coast.  The Delaware Solid Waste Authority and the Southeastern Chester County Refuse Authority have used the data to assist with refuse disposal activities.  DEOS also is working with the College of Agriculture and Natural Resources faculty to assist with evapotranspiration modeling.  Thus, we are striving to make DEOS the highest resolution, most comprehensive state or regional environmental monitoring network available anywhere.  You can find us on the Internet at http://www.deos.udel.edu  – please drop by and let us know how we can better serve you!
