BADM Standards (Beta): DM

Template: Disturbance and Management
Description: Disturbance and Management

Variables with their units and descriptions are found below. If a group is specified in the Group-Required column, the variable is required within that group. Variables without a group and marked required are required for every group. Some variables are marked required / optional with a prefix (e.g., “Optional-a”, “Required-b”). For these variables, only one of the variables with the same prefix should be reported. The Multiple column indicates whether multiple entries of the group are allowed at a tower site.
