BADM: Biological, Ancillary, Disturbance, and Metadata

Biological, Ancillary, Disturbance, and Metadata (BADM) are non-continuous information that describe and compliment flux-met data. BADM include general site description, metadata about the sensors and their setup, maintenance and disturbance events, and biological and ecological data that characterize a site’s ecosystem.

BADM are submitted and distributed following BADM Standards that describe BADM variables, units, and requirements. The BADM Standards are co-developed and used by AmeriFlux, ICOS, Fluxnet and other networks.

Download AmeriFlux BADM (BIF) at the AmeriFlux Download Data page.
An explanation of the BADM Interchange Format (BIF) Data Product is available here.

To Submit BADM to AmeriFlux, see BADM Submission Instructions.

General Instructions for Completing BADM using the Standard xlsx files

  • Use column D and higher in the first worksheet to enter your information. Only use the columns past D when you have more than one entry that you need to put in a row. If you have nothing to enter in a row, leave it blank.
  • Do not enter information in shaded columns.
  • Variables with units of LIST(xxx)—see second worksheet in each template—should use only the choices listed.
  • Enter all values in the units requested. For numeric entries, use only numbers (no letters or symbols).
  • Fill in the submitter’s name—whoever is filling in the template (likely you).
  • See Explanations, the third worksheet, for variable groups that must be reported together.
    • Column A lists the variable groups.
    • Column C has a “p” if a variable is the primary variable for a group of variables.
    • Column D lists an “r” if a variable is a required qualifier for a primary variable. For example, if H2O is entered for FLUX_MEASUREMENTS_VARIABLE on the Site-General-Info Template, the FLUX_MEASUREMENTS_DATE_START is required.
