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.

See the Bundle Browser section for instructions regarding downloading the files.
