Title: Dustfall on the southern high plains of Texas
Author: Crabtree, Gregory
Abstract: Dust and dust storms are a frequent occurrence on the Southern High Plains . According to previous research , the Plains were formed by a “slow and gradual process of aeolian deposition on grassland vegetation” (Gustavson and Holliday , 1999 ) . In the early part of the 20th century the Southern High Plains was transformed into agricultural lands that were highly susceptible to wind erosion . By the mid -1980s much of the highly erodible crop land was removed from production by the Conservation Reserve Program (CRP ) in an effort to reduce the amount of soil available for wind erosion : Bernier (1995 ) showed the declining number of blowing dust days after the introduction of the CRP program . This research project evaluated data from passive dustfall traps located in Lubbock and /or Big Spring , Texas since the late 1990s . The devices were sampled on a quarterly basis and the mass and some of the physical and chemical characteristics of the dust were recorded . Meteorological and air quality data corresponding to the periods of dustfall sampling were also obtained : meteorological variables were collected on an hourly average basis and air quality data as daily averages . An objective was to try and correlate the amount of dustfall with meteorological parameters such as wind speed , temperature and precipitation . By and large , there was no statistically significant relationship between the meteorological parameters and dustfall .
