Climate Impact Meteorological Stations (CLIM-MET) Data and Repeat Photography

Map of study sites

Meteorological measurements and repeat photography support studies of processes and deposits and provide calibration of regional and sub-regional change-detection mapping of vegetation and aeolian deposits using remote-sensing techniques.

The CLIM-MET stations are meteorological/geological stations that are designed to function in remote areas for long periods of time without human intervention. These stations measure meteorological and wind-erosion parameters under varying climatic and land-use conditions to detect and describe ongoing landscape changes. Combined with historic and other data, CLIM-MET data can provide inputs into regional climatic models that describe how the Southwest will respond to future climatic conditions.

Twice a year repeat photographs are taken at each of the seven CLIM-MET sites, once in the spring and once in the fall. Starting from a predetermined point, photos are taken in a 360-degree panorama, showing the site, vegetation and surrounding landscape for that season. In addition to the panoramic site photos, photos are taken of the Sensit instrument, BSNE sediment sampler, and a brick, which is used to characterize surface changes.

Canyonlands National Park in Utah has sites at Virginia Park, Needles, Dugout Ranch, and Corral Pocket. Aeolian activity varies greatly at these four sites in and near Canyonlands National Park having different land-use histories. Two sites are currently grazed and most wind erosion occurs at one of them. Extreme drought in the region during 2002 greatly exacerbated vegetation loss, wind erosion, and dust-event frequency at this site.

Mojave National Preserve in California has sites at North Soda Lake, Balch, and Crucero. All three meteorological stations are located in the in the vicinity of Soda Lake. These stations record standard meteorological parameters along with wind-erosion data and include two kinds of traps for aeolian (wind-blown) sediment. The stations are located in three distinctive geomorphic settings, each scoured by wind: one site (North Soda Lake) near the playa margin on a shallow-gradient slope that carries sheet wash during rare flooding, a second site near a small but periodically active wash (Balch), and the third site (Crucero) in the broad outwash of the Mojave River. At each site small coppice dunes are common, and surficial deposits in the top 15 cm are dominantly sandy (typically greater than 80 percent sand). Deposits between dunes and in washes commonly have higher silt/clay content (20 to 50 percent).
