        <gco:CharacterString>**Please note, this dataset has been superseded by a newer version (see below). Users should not use this version except in rare cases (e.g., when reproducing previous studies that used this version).** USCRN "Processed" Data (labeled as "uscrn-processed"): are interpreted values and derived geophysical parameters with other quality indicators processed from raw data (both Datalogger files and/or Raw Data from GOES and NOAAPort) by the USCRN Team. 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, 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 maximum temperature, hourly minimum 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. These data records are versioned based on the processing methods and algorithms used for the derivations (versions are noted within the data netCDF file), and data are updated when the higher quality raw data become available from stations' datalogger storage (Datalogger Files).</gco:CharacterString>

      <gmd:purpose>
        <gco:CharacterString>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.</gco:CharacterString>

        <gco:CharacterString>LRGSClient collects raw data. CRNingest then reads the raw data, applies QC flags, determines priority, calculates elements, writes data to the database. A number of scripts and programs read data from the database, create YAML files for the Station Monitoring and Reporting Tool, ISD format files for the Integrated Surface Dataset, and text files for transmission through the NOAA Gateway and ftp access for customers.
