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 (104 in Utah) 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 at: http://water.usgs.gov/ or the USGS Oregon District Office home page at: http://or.water.usgs.gov/.
Upper Air Networks
NOAA/NWS Radiosonde Network Low Vertical Resolution Data - The NOAA/NWS typically releases radiosondes twice per day at 0000 and 1200 UTC at 69 locations throughout the US (1 in Utah). During special weather situations the NWS can request to release additional radiosondes at off-times (e.g. 1800 UTC). The low resolution data is sent out over the Global Telecommunications System (GTS) and provides mandatory and significant level observations of pressure, altitude, temperature, dew point, wind speed, and wind direction. There are 3 types of radiosondes utilized within the US network, Vaisala, VIZ (or Sippican), and Microsonde. These data are archived by NOAA/NCDC and other organizations. For further information on the NWS Radiosonde network visit the NWS Upper-air Observations Program home page. A several year archive of GTS upper air data is available at the NOAA/FSL Radiosonde Database.
NOAA/NWS Radiosonde Network High Vertical Resolution Data - The same radiosonde locations mentioned in the previous data set also provide a 6-second vertical resolution data set that provides observations of pressure, temperature, altitude, relative humidity, and azimuth and elevation angles. UCAR/JOSS has developed software to derive 6-second vertical resolution winds from the angle data. These data are archived by NCDC and UCAR/JOSS.
Cooperative Agency Profiler (CAP) Network - The NOAA/FSL ingests data from wind profilers and RASS operated by a number of cooperating agencies. Most of these profilers are 915 MHz, but some are 449 or 50 MHz. Most provide hourly observations of wind speed and direction. The number and location of these can vary through time. As this is being written the network included 58 locations within the US (2 in Utah). Most of the sites are along the US West Coast and in the northeastern US. For further information visit the CAP home page at: http://www.profiler.noaa.gov/jsp/aboutCap.jsp.
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 (4 in Utah). 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).
