Title:Jornada Basin LTER NPP C-CALI meteorological station: Daily summary data beginning 2013
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Daily summary data at NPP C-CALI met station. Average/maximum/minimum air temperature; average/maximum relative humidity and wind speed and average wind direction. These are measured and calculated at an automated meteorological station installed at Jornada LTER NPP C-CALI site. Wind speed is measured at 75 cm, 150 cm, and 300 cm, wind direction at approximately 3m, and air temperature and relative humidity at approximate 2.5m. This climate station is operated by the Jornada LTER Program. This is an ONGOING dataset.

Data processing using the GCE Data Toolbox for MATLAB

Software:
Title:GCE Data Toolbox for MATLAB

Author(s):

Organization:Georgia Coastal Ecosystems LTER
Email Address:

Abstract:

The GCE Data Toolbox is a comprehensive library of functions for metadata-based analysis quality control, transformation and management of ecological data sets. The toolbox is based on the GCE Data Structure, a MATLAB specification for storing tabular data along with all information required to interpret the data and generate formatted metadata (documentation). Metadata fields in the structure are queried by toolbox functions for all operations, allowing functions to process and format values appropriately based on the type of information they represent. This semantic processing approach supports highly automated and intelligent data analysis and ensures data set validity throughout all processing steps.

Quality Control
Quality Control Step 1: 
Description:

Quality control analysis was performed using the GCE Data Toolbox for MATLAB software. Column data types are validated upon importing the table into MATLAB, and qualifier flags are automatically generated for data values based on QA/QC criteria for each data column pre-defined in metadata templates (e.g. value range checks, sanity checks, pattern checks). Automatically-assigned qualifier flags are reviewed graphically and revised or augmented as deemed appropriate by GCE information management staff, based on metadata information from the contributor, values of other measured variables, or statistical tests. Qualifier flags are also assigned to values that are imputed or derived, revised, or otherwise differ from values in the original data submission. A column of coded qualifier flags is generated and included in the data table if flags are assigned to any value in a data column.

Data anomalies: Values of 59 records in Batt_V_Min were flagged as W (Warning (low or high)) for dates: 01/15/2015, 03/08/2015, 03/26/2015, 04/21/2015, 04/23/2015, 04/26/2015-04/27/2015, 05/08/2015, 05/17/2015-05/23/2015, 06/13/2015-06/16/2015, 06/21/2015, 07/01/2015-07/02/2015, 07/04/2015-07/05/2015, 07/07/2015, 07/18/2015-07/21/2015, 08/04/2015, 09/09/2015-09/10/2015, 09/26/2015, 10/23/2015-10/24/2015, 11/30/2015, 12/14/2015, 12/16/2015-12/17/2015, 12/24/2015, 01/08/2016, 01/10/2016, 02/05/2016-02/06/2016, 02/09/2016-02/10/2016, 02/12/2016-02/13/2016, 02/22/2016-02/23/2016, 07/03/2016-07/04/2016, 08/07/2016-08/09/2016, 08/11/2016-08/14/2016.

Description:

Summary: A met station consisting of a 3-meter mast is installed in the 5-meter buffer zone on one side of the 70-meter x 70-meter NPP site in association with a pair of neutron probe access tubes. Air temperature, relative humidity, wind direction and wind speed sensors are mounted on the mast. A vertical wind profile is measured at most sites with anemometers at 0.75m, 1.5m and 3m on the mast. A single anemometer is installed at 3m height at P-COLL and P-SMAL NPP sites due to flooding potential at lower heights. Upward and downward facing pyranometers are installed at 5 sites, 1 for each of the major vegetation zones.

Instrument(s):Temperature Probe; Manufacturer: Campbell Scientific Instruments, Model: CS215; Parameter: Air Temperature Accuracy: +/-0.3°C at 25°C, +/-0.4° (5°C to 40°C), +/-0.9°C (-40°C to 70°C), Range: -40°C to 70°C); Relative Humidity Sensor; Manufacturer: Campbell Scientific Instruments (capacitive relative humidity sensor, Model: CS215/18144); Parameter: Relative Humidity (Accuracy: 2% at 10-90% RH, 4% @ 0-100%; Range: 0% to 100% at -20°C to 60°C); Anemometer; Manufacturer: NRG, Inc (Model: 40C); Parameter: Wind Speed (Range: 0.5 to 50 m/s); Wind Vane; Manufacturer: NRG, Inc (Model: 200P); Parameter: Wind Direction (Range: 360 degrees (1 m/s threshold), Dead band: 8° max, 4° typical)
Description:

Method - Sensor readings are taken at 1 second intervals by a Campbell Scientific Instruments (CSI) CR1000 data logger and converted from analog voltage to calibrated digital data, if necessary, by the CR1000 data logger program (e.g., C-Cali_CR1000_20150925.cr1). Minimum, average, and maximum air temperature and relative humidity; average and maximum wind speed; average and standard deviation of wind direction are calculated by the CR1000 datalogger program and stored in tables in the datalogger storage module at intervals of 5, 30, and 60 minutes and daily. These are downloaded hourly from each remote site via a 900 MHz spread spectrum wireless radio network using CSI LoggerNet software. The data are parsed, quality-checked, documented and archived in the JRN-LTER Information Management office using data retrieval and parsing functions in the GCE Data Toolbox for MATLAB (https://gce-lter.marsci.uga.edu/lter/research/tools/data_toolbox.htm).

Data processing using the GCE Data Toolbox for MATLAB

Software:
Title:GCE Data Toolbox for MATLAB

Author(s):

Abstract:

The GCE Data Toolbox is a comprehensive library of functions for metadata-based analysis quality control, transformation and management of ecological data sets. The toolbox is based on the GCE Data Structure, a MATLAB specification for storing tabular data along with all information required to interpret the data and generate formatted metadata (documentation). Metadata fields in the structure are queried by toolbox functions for all operations, allowing functions to process and format values appropriately based on the type of information they represent. This semantic processing approach supports highly automated and intelligent data analysis and ensures data set validity throughout all processing steps.

Quality Control
Quality Control Step 1: 
Description:

Quality control analysis was performed using the GCE Data Toolbox for MATLAB software. Column data types are validated upon importing the table into MATLAB, and qualifier flags are automatically generated for data values based on QA/QC criteria for each data column pre-defined in metadata templates (e.g. value range checks, sanity checks, pattern checks). Automatically-assigned qualifier flags are reviewed graphically and revised or augmented as deemed appropriate by GCE information management staff, based on metadata information from the contributor, values of other measured variables, or statistical tests. Qualifier flags are also assigned to values that are imputed or derived, revised, or otherwise differ from values in the original data submission. A column of coded qualifier flags is generated and included in the data table if flags are assigned to any value in a data column.

Data anomalies: Values of 59 records in Batt_V_Min were flagged as W (Warning (low or high)) for dates: 01/15/2015, 03/08/2015, 03/26/2015, 04/21/2015, 04/23/2015, 04/26/2015-04/27/2015, 05/08/2015, 05/17/2015-05/23/2015, 06/13/2015-06/16/2015, 06/21/2015, 07/01/2015-07/02/2015, 07/04/2015-07/05/2015, 07/07/2015, 07/18/2015-07/21/2015, 08/04/2015, 09/09/2015-09/10/2015, 09/26/2015, 10/23/2015-10/24/2015, 11/30/2015, 12/14/2015, 12/16/2015-12/17/2015, 12/24/2015, 01/08/2016, 01/10/2016, 02/05/2016-02/06/2016, 02/09/2016-02/10/2016, 02/12/2016-02/13/2016, 02/22/2016-02/23/2016, 07/03/2016-07/04/2016, 08/07/2016-08/09/2016, 08/11/2016-08/14/2016.

Abstract:

Collection of baseline climate data at Jornada LTER NPP sites, New Mexico, supports the environmental monitoring objectives of the Jornada LTER monitoring program. Measurements are aggregated at intervals of 5, 30, and 60 minutes and daily with precipitation additionally with 1 second aggregation during precipitation events. Data are downloaded hourly from each remote site via a 900 MHz spread spectrum wireless radio network. The met station variables measured include air temperature, precipitation, relative humidity, wind direction, wind speed. Solar and barometric pressure are measured at a subset of sites.
