Regional Surface Meteorological Networks

WJAR WeatherNet - WJAR-TV in Providence, Rhode Island operates this network of 53 stations located primarily at schools throughout Rhode Island, Massachusetts and 1 in New York (37 in Massachusetts). 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 WJAR network page. No map yet.

State and Local Surface Meteorological Networks

None.

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 (3 in Rhode Island) 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 Rhode Island). These data are archived at NOAA/NCDC as data set TD 3260. For further information visit the NOAA/NCDC TD3260 page.

Radiation and Flux Networks

None at present

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 (8 in Rhode Island) 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 Rhode Island District Office home page.

Upper Air Networks

None at present
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 (5 in Rhode Island). The network provides 15-minute observations of air temperature, wind speed, wind direction, barometric pressure, water temperature, and water level.
