File type abbreviation: trace

The tracers subset category contains variables extracted from the raw wrfout files related to the four inert tracers added to WRF for LASSO-CACTI. More information about the tracers is provided in the Modeling Methodology Section. The data are on the raw model levels listed in Table 20.
