        abstract:  USCRN Raw Transmitted Data is level 0 data received from the USCRN stations that are transmitted continuously. The data values are ingested with a unique 18-bit format due to satellite transmission limitations (documentation will be archived along with data); code is also included to read the bit format and parse out values for a stream. As of 2017, there are 26 possible stream format versions over the history of the USCRN network; format versions are dependent on hardware/software upgrades to the USCRN network and may increase over time. The data stream includes observations taken by USCRN stations for temperature, precipitation, etc., but users are encouraged to use downstream, processed versions of the data, due to the complexity of reading the satellite-encoded format (see documentation for more information). As of 2017, data are ingested via various mechanisms, including: an LRGS receiver connected to the NOAA and EDDN satellite networks, a domestic communications satellite (DOMSAT) receiver located at NCEI, and parsed data from NOAAPort. Numerous data files from different sources (usually with a distinct filenaming convention based on source) are collected throughout the month and are separated into subdirectories based on the date of ingest into the CRN database. Files from all sources and all days for the month are packaged together into a monthly archive file.
        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 will be used in operational climate monitoring activities and for placing current climate anomalies into an historical perspective. The USCRN Raw data provides a Near-Real-Time data flow that can be used to produce high-quality datasets on a faster time scale.

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. All specifics are documented and software is in Subversion.

            statement:  The level 0 data received from the USCRN stations are transmitted continuously via satellite. The data values are ingested with a unique 18-bit format due to satellite transmission limitations (see documentation for more information). As of 2016, there are 26 possible stream format versions over the history of the USCRN network; format versions are dependent on hardware/software upgrades to the USCRN network and may increase over time. The USCRN Program at NCEI is the primary source of the raw data, performs QA/QC functions, and prepares the data for archive and distribution.

                description:  In September of 2017, the process for archiving the raw transmitted USCRN data was changed to better accommodate long-term use and stewardship by the USCRN Program. In 2015, the LRGS system changed and data in 6117_01 was no longer complete. The 2017 Update addresses this issue and ensures the completeness of the historical period of record (separate from the original archive, to ensure provenance). This update reinforces the USCRN archive data quality. For more information, see documentation or contact the USCRN Program.
