Regional Surface Meteorological Networks

WMAR WeatherNet - WMAR-TV in Baltimore, Maryland operates this network of 131 stations located primarily at schools throughout Maryland, eastern Pennsylvania, and Delaware (1 in Delaware). The network provides up to 1-minute observations of air temperature, relative humidity, wind speed, wind direction, precipitation, and barometric pressure. For further information visit the WMAR network page. No map yet.

WCAU SchoolNet - WCAU-TV in Philadelphia, Pennsylvania operates this network of 230 stations located at schools throughout Pennsylvania and surrounding states (29 in Delaware). The network provides up to 1-minute observations of air temperature, relative humidity, wind speed, wind direction, precipitation, and barometric pressure. For further information visit the WCAU network page. No map yet.

State and Local Surface Meteorological Networks

Delaware Air Monitoring Network - The Delaware Department of Natural Resources and Environmental Control Air Quality Management operates this network of 6 stations with locations throughout the state of Delaware. All stations provide hourly observations of wind speed and wind direction. Some stations also provide air temperature, relative humidity, precipitation, and/or soil temperature. For further information visit the Air Quality Management page.

Precipitation and Radar Networks

NOAA/National Centers for Environmental Prediction (NCEP) Hourly Precipitation Data - NOAA/NCEP routinely develops a National Multi-sensor Hourly Precipitation Analysis (Stage II) data set from hourly radar precipitation estimates and from hourly gage reports. The gage data includes hourly observations from ~4000 gages across the US (2 in Delaware) collected by the NOAA River Forecast Centers and sent to NCEP. Further information on these data is available at: http://wwwt.emc.ncep.noaa.gov/mmb/ylin/pcpanl/.

NOAA/NWS Cooperative Observer 15-minute Precipitation Network - The NOAA/NWS routinely collects 15-minute observations of precipitation from Fisher-Porter and Universal rain gages operated by 2777 cooperative observers located throughout the US (2 in Delaware). These data are archived at NOAA/NCDC as data set TD 3260. For further information visit the NOAA/NCDC TD3260 page.

Weather Surveillance Radar 1988 Doppler (WSR-88D) Network - The NOAA/NWS and the Department of Defence operate this network of 143 WSR-88D radars across the continguous US (1 in Delaware). The Level II data are the three meteorological base data quantities (reflectivitiy, mean radial velocity, and spectrum width) and are recorded at all NWS and most DOD sites. Level II data are then processed in order to create a number of meteorological analysis products known as Level III data. Level III data are recorded at the NWS sites. The Level III products included base reflectivity, base spectrum width, base velocity, composite reflectivity, echo tops, velocity azimuth display (VAD) wind profile, vertically integrated liquid (VIL), 1-hour precipitation, storm total precipitation, hail index overlay, mesocyclone overlay, severe weather probability overlay, storm structure, storm tracking information overlay, and tornadic vortex signature overlay. All Level II and III data are archived at NOAA/NCDC. For further information visit the NOAA/NCDC Radar Resources page at: http://www.ncdc.noaa.gov/oa/radar/radarresources.html or the NOAA Radar Operations Center at: http://www.roc.noaa.gov/.

Radiation and Flux Networks

Soil Networks

None at present.

Hydrology Networks

United States Geological Survey (USGS) Streamflow Network - The USGS (part of the US Department of the Interior) operates this network of 7237 streamflow gages (12 in Delaware) at locations throughout the US. The network provides hourly or more frequent observations of stage (water level) from which discharge (flow) is comuputed using a stage-discharge rating relation. The rating is defined by occasional direct current-meter measurements of discharge. All data are available through the USGS and the district offices in each state. Many of these gages provide realtime data relayed via the GOES satellite data collection system. The realtime data are provisional data that have not been reviewed or edited. These realtime data may be subject to significant change and are not citeable until reviewed and approved by the USGS. Realtime data may be changed after review because the stage-discharge relationship may have been affected by: 1) backwater from ice or debris; 2) algal and aquatic growth in the stream; 3) sediment movement; and 4) malfunction of recording equipment. Each station record is considered provisional until the data are published. The data are usually published with 6 months of the end of the water year (1 October to 30 September). Data users are cautioned to consider carefully the provisional nature of the information before using it. For further information on the USGS stremflow network visit the USGS Water Resources of the United States page or the USGS Maryland, Delaware, and D.C. Area District Office home page.

Upper Air Networks

Ground Based Global Positioning System (GPS) Meteorology Demonstration Network (GPS-MET) - The NOAA/FSL ingests data from 323 GPS locations around the US operated by many different agencies (1 in Delaware). Typically each location provides 30-minute observations of integrated precipitatable water along with a number of surface meteorology parameters (air temperature, relative humidity, barometric pressure, etc). For further information visit the GPS-MET home page.

Aerosol Networks
None at present.
Coastal Networks

Physical Oceanographic Real-Time System (PORTS) - The National Ocean Service (NOS) operates this network of 51 weather stations with locations within bays and harbors along the Atlantic and Gulf of Mexico coastlines (4 in Delaware). The network provides 15-minute observations of air temperature, wind speed, wind direction, barometric pressure, water temperature, and water level.
