Sevilleta Meteorological Network (SevMET) was first established in 1988 as a network of automated meteorological stations with the primary objective of collecting long-term climate records across a variety of ecoregions in the SNWR representative of the southwestern US. By 2002, ten complete stations were operating, along with two partially instrumented stations. These stations were strategically located to capture climatic variables across vegetation and elevation gradients spanning a broad spatial extent, as well as to supplement nearby research studies, such as long-term plant and animal monitoring transects. Complete stations currently measure on an hourly basis a standard suite of meteorological variables that include air temperature, relative humidity, wind speed and direction, precipitation solar radiation, and barometric pressure, while partial stations measure only air temperature, wind speed, and precipitation. Funnel-and-bottle collection systems located at each station enable monthly analyses of precipitation chemistry.
Below: Existing and proposed (highlighted) stations in the SNWR that comprise SevMET. Partially instrumented stations are noted with asterisks. Years indicate when station was established. Elevation is expressed in meters. Grassland biome is abbreviated by grass, shrubland by shrub, and woodland by wood. Soil classifications were obtained from the USDA Web Soil Survey (Soil Survey Staff 2017). Mean annual precipitation (MAP), expressed in mm, and the coefficient of variation (CV) of MAP were calculated using existing long-term datasets (Moore 2017).
