BADM Group Overview
BADM variables in this group are organized as shown below. The overview highlights what variables are required per group. It also indicates which variables cannot be specified together ( OR ) in the same group entry. 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:

Examples
| Variable Requirements | Units | Description |
|---|---|---|
| PHEN_EVENT_TYPE Required | LIST(PHEN_EVENT) Show | Phenology event type Use predefined list to indicate phenology event type. |
| PHEN_EVENT_STATUS Ⓒ Required | LIST(PHEN_STATUS) Show | Phenology event status Use predefined list to indicate the temportal status of the phenology event type. |
| PHEN_EVENT_SPP Ⓒ Optional-a | Scientific name | Phenology event species (taxa) Vegetation species being described by the measurement. To enter a plant species, use the scientific name (Genus species Author or Genus Author). Please refer to www.theplantlist.org for current scientific names and authors. If the measurement includes all vegetation present, do not enter a value. Do not use SPP if reporting VEGTYPE. |
| PHEN_EVENT_VEGTYPE Ⓒ Optional-a | LIST(VEGTYPE) Show | Phenology event vegetation type Use the predefined list to indicate the type of vegetation being described by the measurement (e.g., Grass, Evergreen Tree, Deciduous Tree, etc). If the measurement includes all vegetation present, do not enter a value. If vegetation type is not in predfined list, enter "Other/Not in list" and describe briefly in Approach. Do not use VEGTYPE if reporting SPP. |
| PHEN_EVENT_DATE Ⓒ Required-b | YYYYMMDDHHMM | Phenology event date for the reported statistic Report the date at the precision known for the specified PHEN_EVENT_DATE_STATSTIC. Allowed reporting precision are YYYYMMDD and YYYYMMDDHHMM. For variability in the date of the phenological event, consider reporting percentiles if possible or use PHEN_EVENT_DATE_STD_DEV or PHEN_EVENT_DATE_MEAS_UNC. |
| PHEN_EVENT_DATE_STATISTIC Ⓒ Required | LIST(STATISTIC) Show | Phenology event date statistic Only report statistics that can be expressed as a date (e.g., Mean, Minimum, Maximum, Single Observation, and Percentiles). For Standard Deviation and Measurement Uncertainty statistics, use PHEN_EVENT_DATE_STD_DEV or PHEN_EVENT_DATE_MEAS_UNC. |
| PHEN_EVENT_DATE_STATISTIC_METHOD Ⓒ Optional | LIST(STATISTIC_METHOD) Show | Phenology event date 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. |
| PHEN_EVENT_DATE_STATISTIC_NUMBER Optional | integer number | Number of observations used to determine phenology event date statistic Number of observations (samples / replicates) used to calculate the STATISTIC for the reported measurement. |
| PHEN_EVENT_DATE_STD_DEV Optional | days | Phenology event date standard deviation Standard deviation may be reported from a sample population that consists of individual or aggregated samples (observations). If the distinction is important, specify in comments. |
| PHEN_EVENT_DATE_MEAS_UNC Optional | days | Phenology event date spatial measurement uncertainty Report 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. |
| PHEN_EVENT_APPROACH Optional | free text | Phenology event observation approach |
| PHEN_EVENT_COMMENT Optional | free text | Phenology event comments |
