BADM Group Overview

BADM variables in this group are organized into subgroups as shown below. The overview highlights what variables are required per subgroup. It also indicates which variables cannot be specified together ( OR ) in the same group entry. Variables in "Applies to All" are included with all subgroups. See BADM Basics for more details.

Multiple entries of this BADM group can be reported per site. However, combinations of variables must be unique. Read more:

    Requirements
    Units Description
    SOIL_DEPTH
    1-Required
    cmSoil depth
    Report the depth (thickness) of the soil that is in theory accessible to the plant roots or up to the first rock layer as measured from the top of the litter layer. Define depth used in Approach.
    SOIL_DEPTH_STATISTIC
    1-Required
    LIST(STATISTIC) ShowSoil depth statistic
    The statistic for the measurement reported. Use predefined list (e.g., mean, min / max, standard deviation, etc).
    STATISTIC Options×
    OptionDescription
    MeanAverage (mean) value of sample population
    Standard DeviationStandard deviation may be reported from a sample population that consists of individual or aggregated samples (observations). If the distinction is important, specify in STATISTIC_METHOD or Comments.
    MinimumMinimum value
    1st PercentileQuantile at 1% of distribution
    5th PercentileQuantile at 5% of distribution
    10th PercentileQuantile at 10% of distribution
    25th PercentileQuantile at 25% of distribution
    Median - 50th PercentileMedian - Quantile at 50% of distribution
    75th PercentileQuantile at 75% of distribution
    90th PercentileQuantile at 90% of distribution
    95th PercentileQuantile at 95% of distribution
    99th PercentileQuantile at 99% of distribution
    MaximumMaximum value
    Single observationSingle observation that is not a calculated statistic of replicates either to get a robust estimate or for spatial variability analysis. For example a single biomass observation may be the vegetation harvested in a single 1 x 1 meter area.
    Measurement UncertaintyReport uncertainty as a plus or minus value in the measurement units. For example, enter 1.5 for +/- 1.5 units. Uncertainty may be reported from the instrument's specifications, determined empirically, or estimated by the tower team. Please describe such details in Approach. For uncertainty values that are better described by a range, a percent, or other, please enter information in Comments.
    SOIL_DEPTH_STATISTIC_METHOD
    1-Optional
    LIST(STATISTIC_METHOD) ShowSoil depth statistic method
    Method used to generate the reported statistic (e.g., aggregate of individuals, aggregate of sample aggregates) from observations representing the same time period. Use predefined list. The aggregation method is not meant to describe temporal aggregations for example in calculations of higher frequency observations (e.g., sub-minute) to lower frequency observations (e.g., hourly) at a single location.
    STATISTIC_METHOD Options×
    OptionDescription
    Aggregate of individual observationsThe statistic is aggregated from individual observations located within the site. Observations may be grouped into sample areas (e.g., plots) within the site but those groupings are ignored. Statistics generated from individual observations directly yield information on the site generally. The statistic may represent spatial characteristics of the measurement within the site (e.g., spatial heterogeneity) and/or characteristics due to other factors (e.g., population variability).
    Aggregate of sample aggregatesThe statistic is aggregated from aggregated individual observations located in sample areas within the site. For example, individual observations are made in 5 sample plots within a site. "Aggregate of sample aggregates" is used if a plot statistic (e.g., Mean) is first calculated, and then the plot values are aggregated to calculate the site statistic. Statistics generated by this approach are often used to highlight the spatial characteristics within the site (i.e., the spatial heterogeneity of measurement within the site).

    SOIL_DEPTH_STATISTIC_NUMBER
    1-Optional
    integer numberNumber of observations used to determine soil depth statistic
    Number of observations (samples / replicates) used to calculate the STATISTIC for the reported measurement.
    SOIL_DEPTH_ORG
    2-Required
    cmSoil depth of organic horizon
    Report the depth (thickness) of the organic soil horizon as measured from the top of the litter layer.
    SOIL_DEPTH_ORG_STATISTIC
    2-Required
    LIST(STATISTIC) ShowSoil depth of organic horizon statistic
