    BADM for This Site

    Access the Biological, Ancillary, Disturbance and Metadata (BADM) information and data for this site.

    BADM contain information for many uses, such as characterizing a site’s vegetation and soil, describing disturbance history, and defining instrumentation for flux processing. They complement the flux/met data.

    * Online updates are shown on the Overview tab real time. However, downloaded BADM files will not reflect those updates until they have been reviewed for QA/QC.
