# aa\_int\_cnt

Number of print intervals for average annual output

If *aa\_int\_cnt* = 0, the model will print average annual output for the entire period. If *aa\_int\_cnt* > 0, the end years of the print intervals have to be specified by the user by listing them in chronological order in the same line as *aa\_int\_cnt*. 

{% hint style="info" %}
Example: If *aa\_int\_cnt* = 3   1955   1965   1975, average annual results will be printed for the time periods ending in 1955, 1965, and 1975.
