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 (83 in Kentucky) 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 (63 in Kentucky). These data are archived at NOAA/NCDC as data set TD 3260. For further information visit the NOAA/NCDC TD3260 page at: http://ols.nndc.noaa.gov/plolstore/plsql/olstore.prodspecific?prodnum=C00505-TAP-A0001

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 (178 in Kentucky). These precipitation data are included as part of the NCEP Precipitation data set described above. For further information visit the AFWS home page.

Jefferson County Rain Gauge Network - Jefferson County, Kentucky operates this network of 45 rain gauges with locations throughout the county (located in north-central Kentucky around Louisville). The network provides 5-minute observations of rainfall. For further information visit the network page. Map on web page.

Tennessee Valley Authority (TVA) Precipitation Network - TVA operates this network of 243 precipitation gages throughout its service area in the southeastern US (6 in Kentucky). The network provides 6-hourly observations of precipitation. For further information visit the TVA home page.

Weather Surveillance Radar 1988 Doppler (WSR-88D) Network - The NOAA/NWS and the Department of Defense operate this network of 143 WSR-88D radars across the contiguous US (4 in Kentucky). The Level II data are the three meteorological base data quantities (reflectivity, 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

None at present.

Soil Networks

Soil Climate Analysis Network (SCAN) - The SCAN is operated by the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS). The network provides hourly observations of air temperature, relative humidity, wind speed, wind direction, solar radiation, precipitation, barometric pressure, snow water content, snow depth, soil temperature (at 2, 4, 8, 20, and 40 cm depths), and soil moisture (at 2, 4, 8, 20 and 40 cm depths). The 80 SCAN stations are located across the US in primarily agricultural regions (1 in Kentucky). For further information visit the SCAN home page.

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 (143 in Kentucky) at locations throughout the US. The network provides hourly or more frequent observations of stage (water level) from which discharge (flow) is computed 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 streamflow network visit the USGS Water Resources of the United States page or the USGS Kentucky 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 (7 in Kentucky). 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 Kentucky). 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.
