The temporal resolution and parameters measured vary by station. Up to hourly observations of air temperature, precipitation, snow depth, and snow water content are typically provided. Other parameters that may be available include relative humidity, wind speed, wind direction, solar radiation, soil moisture, and soil temperature. These data are archived by the NRCS, Western Regional Climate Center, and other.

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 (2 in Idaho). 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
University of Oregon Solar Radiation Monitoring Laboratory Network - The University of Oregon Solar Radiation Monitoring Laboratory Network consists of 21 stations located throughout Oregon and nearby states (5 in Idaho). The parameters measured vary by station but typically provide up to 5-minute observations of global, direct and diffuse solar along with some meteorological parameters. For further information visit the SRML Network home page at: http://solardat.uoregon.edu/
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 (4 in Idaho). 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 (125 in Idaho) 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 at: http://water.usgs.gov/ or the USGS Idaho District Office home page at: http://id.water.usgs.gov/.
USDA/ARS Watershed Research - The USDA/ARS operates a number of research watersheds throughout the US. Some of the best instrumented include the Reynolds Creek in Idaho, the Walnut Gulch in Arizona, the Southern Plains Experimental Range in Oklahoma, the Little Washita River in Oklahoma, the Blackland Prairie in Texas, the Goodwater Creek in Missouri, the Walnut Creek in Iowa, Goodwin Creek in Mississippi, the Little River in Georgia, the Oconee River in Georgia, the North Appalachian Watershed in Ohio, the National Agriculture Research Center in Maryland, and the Mahantango Creek in Pennsylvania. Most of these have at least one surface meteorological station and a precipitation gage network.

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 Idaho). 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.
Idaho National Engineering and Environmental Laboratory (INEEL) Wind Profiler - The NOAA/Air Resources Laboratory/Field Research Division operates a wind profiler at the INEEL site in southeastern Idaho. The profiler provides 30-minute vertical profiles of wind speed and wind direction. For futher information visit the Field Research Division home page.	No Map.
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 Idaho). 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 at: http://www.gpsmet.noaa.gov/jsp/index.jsp.
