Fig. 1. Location of sampling plots relative to New Mexico, USA, and New Mexico State Highway 501, which borders the west side of Los Alamos National Laboratory. The burn gradient is represented as variously shaded boxes. Within each burn category, the primary sampling sites are represented as larger rectangles and secondary sites represented as smaller rectangles. The map also shows the locations of the TA-6 meteorological tower and the sites used to establish relationships between HDF (horizontal dust flux) and VDF (vertical dust flux).
