    Ⓒ Required    		LIST(FLUX_METHOD) ShowMethod used to measure the flux variables
    Method used to measure the flux of the variable reported in FLUX_MEASUREMENTS_VARIABLE. Use the predefined list. Report different variable-method combinations in separate entries (e.g., add a new entry for CO2 flux using eddy covariance, one for CO2 flux using chambers, one for H2O with eddy covariance, etc.).

    The first date of any measurements of the flux variable with the indicated method. Please report the start date at the precision known. Allowed reporting precision are YYYY, YYYYMMDD, and YYYYMMDDHHMM.
    FLUX_MEASUREMENTS_DATE_END
    Required    		YYYYMMDDHHMMDate when data collection for the reported flux variable/method ended
    The end date should only be specified when no current or future measurements of the flux variable with the indicated method are planned. Please report the end date at the precision known. Allowed reporting precision are YYYY, YYYYMMDD, and YYYYMMDDHHMM.
    FLUX_MEASUREMENTS_OPERATIONS
    Ⓒ Required    		LIST(FLUX_OPERATIONS) ShowOperational status of flux measurements
    Use the predefined list of status options to report the way this variable-method combination is collected (e.g. continuously).
