AmeriFlux FLUXNET-1F US-Ses Sevilleta shrubland

This is the AmeriFlux Management Project (AMP) created FLUXNET-1F version of the carbon flux data for the site US-Ses Sevilleta shrubland. This is the FLUXNET version of the carbon flux data for the site US-Ses Sevilleta shrubland produced by applying the standard ONEFlux (1F) software. Site Description - The Sevilleta Desert Shrubland site is located in Larrea-dominated shrubland in the northern Chihuahuan Desert of the Rio Grande Valley, on the Sevilleta National Wildlife Refuge (SNWR). The site is within the McKenzie Flats area of the Sevilleta National Wildlife Refuge (NWR). McKenzie Flats is an extensive (~130 km2), nearly flat, mixed-species desert grassland bounded on the east by Los Pinos Mountains and on the west by the Rio Grande. Historically, this area has been used for livestock grazing; however, the McKenzie Flats have not been grazed since 1973 and the effects of this previous grazing are considered negligible for the purposes of this study. The density of Larrea at this site is 0.9 m-2 , interspersed with C4 perennial grasses (Bouteloua gracilis, B. eriopoda, Sporobolis spp., Hilaria jamesii, Muhlenbergia spp.). Sixty percent of mean annual precipitation comes in isolated, short duration showers during the monsoon season (July – September); the remainder arrives with winter frontal systems, although with considerable year-to-year variation.
