Metadata Input

A collection of site descriptors and variables are required for the processing of the CRNS data.

Below shows the list of metadata variables included in the templates.

NAME	UNITS	DESCRIPTION	REQUIRED
COUNTRY	-	Country code for location of site	Yes
SITENUM	-	Assigned number for site	Yes
INSTALL_DATE	-	Date of site installation	No
LONGITUDE	degrees	Longitude of site	Yes
LATITUDE	degrees	Latitude of site	Yes
ELEV	m	Elevation of site above sea level	Yes
TIMEZONE	-	Timezone of the site	No
RC	gv	Cutoff Rigidity of the site	No
LW	% (0:1)	Percent Lattice Water from site specific calibration data (as a number between 0 and 1)	Yes
SOC	% (0:1)	Percent Soil Organic Carbon from site specific calibration data (as a number between 0 and 1)	Yes
BD	g/cm3	Bulk Density from site specific calibration data	Yes
N0	-	Theoretic maximum neutron count for site (dry conditions)	Yes
AGBWEIGHT	kg/m2	Live woody above ground biomass estimates from ECMWF biomass data	No
BETA_COEFF	-	Store of the calculated beta coefficient (see pressure calculations) for each individual site	Yes
REFERENCE_PRESS	mb	Reference pressure calculated using elevation	Yes
RAW_DATA_FILEPATH	-	Filepath of the raw data	Yes
MAX_PRECIPITATION	mm	Maximum value of precipitation. Values above this are cut off	No
SM_MAX	cm3/cm3	Maximum value of SM. Values above this are cut off	No

Additional Info

Unlike CRSPY, CRSPY_lite requires the N0 value, used to calibrate the data, to be a user input. If no N0 value available, try the relevent CRNS network website to retrieve one.

http://www.crnslab.org/ is a great resource. It is especially useful in finding site specific cut-off rigidity (RC) if it is not already available in data.
