abstract: USCRN Processed data are interpreted values and derived geophysical parameters processed from raw data by the USCRN Team. Data were interpreted and ingested into a database, but are also available as netCDF files exported from the database. The "Version 2" of the dataset denotes the application of a new precipitation algorithm to calculate values. (See documentation for more information). Climate variable types include air temperature, precipitation, soil moisture, soil temperature, surface temperature, wetness, global solar radiation, relative humidity, and wind at 1.5 m above the ground. Many additional engineering variables are also available. These data have been decoded from the raw data streams, quality-flagged, and processed into level 1 hourly data (the only applied quality control is rounding some values as they enter the database), and includes additional calculated values such as precipitation (5-minute and hourly), hourly max/min temperature, average temperature (5-minute and hourly), soil moisture (volumetric water content, 5-minute values at the 5 cm depth and and hourly values at all depths) for all dielectric values in range, layer average soil moisture (5 minute and hourly), and layer average soil temperature (5 minute and hourly). It is the general practice of USCRN to not calculate derived variables if the input data to these calculations are flagged.
purpose: USCRN's primary goal is to provide future long-term homogeneous observations of temperature and precipitation that can be coupled to long-term historical observations for the detection and attribution of present and future climate change. Each station location is carefully selected to capture the representative climate regions of the nation. Data from the USCRN/USRCRN will be used in operational climate monitoring activities and for placing current climate anomalies into an historical perspective. These files are in an easy-to-use standard format that will ensure users from many different backgrounds will be able to use the data for research or climate understanding.

extent: #boundingExtent
lineage: (LI_Lineage)
statement: Processed data are interpreted from raw satellite data which is transmitted by stations as a raw data stream to the NCEI, then the processed files are updated when new datalogger files are delivered. All data is passed through a basic Quality Assurance process, then flagged , if necessary. Some additional values are calculated from these interpreted values. See documentation for more information.
processStep: (LE_ProcessStep)
description: The station transmits observations in near-real-time through the GOES Data Collection System (DCS). Multiple satellite ground systems receive the encoded data and send to the LRGS system. Once decoded, the data is then uploaded into the USCRN database. The database supplies data to users in various formats, including a netCDF format which is then archived.
