**Tool**. Runs: [gridmet.launcher](../../../gridmet/doc/members/launcher)

## Description

This tool preprocesses a NetCDF (.nc) file and aggregates gridded data 
over shapes (zip codes or counties) and time. It produces daily mean values.
The tool expects daily values in teh grid nodes.

The tool expects multiple (daily) values for one variable in every grid node. 
The variables are expected to be formatted as they are in

See also [aggregate_wustl.cwl](aggregate_wustl) for aggregating
single variable values with multiple variables in every node as formatted
