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.

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 Missouri). For further information visit the SCAN home page.
North Central River Forecast Center (NCRFC) Soil Temperature Network - The NCRFC operates this network of 47 stations (1 in Missouri) that collect weekly readings of soil temperature at depths of 2, 4, 8, 20, 40 and 60 in at locations throughout the north central US. For further information visit the NCRFC Soil Temperature Network web 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 (164 in Missouri) 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 Missouri District Office home page.

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. For further information visit the USDA/ARS Watershed Research home page.

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 Missouri). 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.
NOAA Profiler Network (NPN) - The NOAA/Forecast Systems Laboratory (FSL) operates this network of 32 404 MHz wind profilers primarily across the central portion of the United States (3 in Missouri). Each site provides 6-minute and hourly vertical profiles of wind speed and wind direction. Additionally, 11 of the NPN sites have a collocated Radio Acoustic Sounding System (RASS) that provides 6-minute and hourly vertical profiles of virtual temperature (none in Missouri). For further information visit the NPN home page. An archive of the hourly wind profiles is available from NCAR/SCD.
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 (5 in Missouri). 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).
