SA Required | years | Stand age The age of standing live trees. Stand age is typically only reported for forest ecosystems. If reporting stand age for non-forest ecosystems, describe details in Approach. |
SA_STATISTIC Ⓒ Required | LIST(STATISTIC) Show | Stand age statistic The statistic for the measurement reported. Use predefined list (e.g., mean, min / max, standard deviation, etc). |
SA_STATISTIC_METHOD Ⓒ Optional | LIST(STATISTIC_METHOD) Show | Stand age 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. |
SA_STATISTIC_NUMBER Optional | integer number | Number of observations used to determine stand age statistic Number of observations (samples / replicates) used to calculate the STATISTIC for the reported measurement. |
SA_APPROACH Optional | free text | Stand age measurement approach |
SA_DATE Ⓒ Required-a | YYYYMMDDHHMM | Stand age measurement date Please report the date at the precision known. Allowed reporting precisions are YYYY, YYYYMM, YYYYMMDD, and YYYYMMDDHHMM. For measurements conducted during a campaign or for temporal averages, use DATE_START and DATE_END instead of DATE. |
SA_DATE_START Ⓒ Required-a | YYYYMMDDHHMM | Start date of stand age measurment Start date of a measurement campaign or start date of a temporal average. Please report the date at the precision known. Allowed reporting precisions are YYYY, YYYYMM, YYYYMMDD, and YYYYMMDDHHMM. |
SA_DATE_END Required | YYYYMMDDHHMM | End date of stand age measurment End date of a measurement campaign or end date of a temporal average. Please report the date at the precision known. Allowed reporting precisions are YYYY, YYYYMM, YYYYMMDD, and YYYYMMDDHHMM. |
SA_DATE_UNC Optional | days | Uncertainty in the stand age measurement date If uncertainty in the start date differs than end date, report the uncertainty for start date here in DATE_UNC and the uncertainty for end date in Comments. |
SA_COMMENT Optional | free text | Stand age comments |
