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:

Variable Requirements | Units | Description |
---|---|---|
SOIL_DEPTH 1-Required | cm | Soil 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) Show | Soil depth statistic The statistic for the measurement reported. Use predefined list (e.g., mean, min / max, standard deviation, etc). |
SOIL_DEPTH_STATISTIC_METHOD Ⓒ 1-Optional | LIST(STATISTIC_METHOD) Show | Soil 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. |
SOIL_DEPTH_STATISTIC_NUMBER 1-Optional | integer number | Number 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 | cm | Soil 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) Show | Soil depth of organic horizon statistic The statistic for the measurement reported. Use predefined list (e.g., mean, min / max, standard deviation, etc). |
SOIL_DEPTH_ORG_STATISTIC_METHOD Ⓒ 2-Optional | LIST(STATISTIC_METHOD) Show | Soil depth of organic horizon 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. |
SOIL_DEPTH_ORG_STATISTIC_NUMBER 2-Optional | integer number | Number of observations used to determine soil depth of organic horizon statistic Number of observations (samples / replicates) used to calculate the STATISTIC for the reported measurement. |
SOIL_DEPTH_APPROACH Optional | free text | Soil depth measurement approach |
SOIL_DEPTH_DATE Ⓒ Required | YYYYMMDDHHMM | Soil depth measurement date Please report the date at the precision known. Allowed reporting precisions are YYYY, YYYYMM, YYYYMMDD, and YYYYMMDDHHMM. |
SOIL_DEPTH_DATE_UNC Optional | days | Uncertainty in the Soil depth measurement date |
SOIL_DEPTH_COMMENT Optional | free text | Soil depth comments |
