Regional Surface Meteorological Networks

CAMNET - The Northeast States for Coordinated Air Use Management (NESCAUM) operates this network of 6 stations with locations throughout the northeast US (1 in Connecticut). The network provides 15-minute observations of air temperature, relative humidity, wind speed, wind direction, precipitation, and visibility. Each station also has a webcam on site. For further information visit the CAMNET home page.

WNBC WeatherNet - WNBC-TV in New York, New York this network of 485 stations located primarily at schools throughout New York, New Jersey and Connecticut (28 in New York). 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 WNBC network page. No map yet.

State and Local Surface Meteorological Networks

Connecticut Department of Transportation (DOT) Road Weather Information System (RWIS) Network - The Connecticut DOT operates this network of 26 stations with locations along roadways throughout the state of Connecticut. The network provides variable (hourly or higher) resolution observations of air temperature, dew point, relative humidity, and wind speed. For further information visit the Connecticut DOT weather roundup page.
WTNH WeatherNet - WTNH-TV in Hartford, Connecticut operates this network of 19 stations located primarily at schools throughout Connecticut. 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 WTNH network page. No map yet.

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 (20 in Connecticut) 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 (16 in Connecticut). These data are archived at NOAA/NCDC as data set TD 3260. For further information visit the NOAA/NCDC TD3260 page.

Integrated FLood Observing and Warning System (IFLOWS) Precipitation Network - The IFLOWS precipitation network is a collection of various state operated Automated Flood Warning System (AFWS) networks throughout the mid-Atlantic and northeastern portions of the United States. The network is comprised of 1530 precipitation stations that provide 15-minute observations of precipitation (52 in Connecticut). These precipitation data are included as part of the NCEP Precipitation data set described above. For further information visit the AFWS home page.

Radiation and Flux Networks

Ameriflux Network - The Ameriflux network consists of 54 sites conducting long-term measurements of CO2, water and energy fluxes throughout the US (1 in Connecticut). The typical observational frequency is 30 minutes. The parameters measured at each site vary, but Ameriflux has defined a core set of parameters that most sites collect, including fluxes of CO2, energy and water, basic meteorological and radiation parameters, and soil temperature and moisture.

Soil Networks

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 (39 in Connecticut) 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 Connecticut District Office home page.

Integrated FLood Observing and Warning System (IFLOWS) Streamflow Network - The IFLOWS network is a collection of various state operated Automated Flood Warning System (AFWS) networks throughout the mid-Atlantic and northeastern portions of the United States. The network is comprised of 275 streamflow gages that provide 15-min stage observations (16 in Connecticut). For further information visit the AFWS 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 Connecticut). 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.
