2008-Nov 2022 overview of fluxes from US-Mpj

Top panel: Monthly net ecosystem exchange of carbon (NEE, net carbon balance where positive values indicate net carbon release to the atmosphere and negative values indicate net carbon stored in the ecosystem). Second from top: Monthly sums of Gross Primary Production (GPP, total carbon entering ecosystem through photosynthesis) and Ecosystem Respiration (RE, total carbon released through both autotrophic and heterotrophic respiration).  Third from top: Monthly sums of Evapotranspiration (ET, total water released to atmosphere through transpiration and evapotranspiration) and incoming solar radiation (Rg).  Bottom panel: Monthly precipitation totals (Precip) and average air temperature (bottom).

History of site

This tower has been operational since Nov. 2007.  This tower is located in central New Mexico on an extensive mesa  approximately 25 km south of Mountainair, NM, owned by the Deer Canyon Preserve. The installation of this site was funded by the USFS, and funding for this site has come from NASA-ROSES (2010-2013) and DOE (2 awards, DOE EPSCoR University-Lab, and DOE BER).  This site is currently funded through Ameriflux Management Project, which started in 2013. This site is also the control site for a large-scale manipulation project started in 2009 to quantify the consequences of large scale coniferous mortality in semi-arid woodlands described in more detail here.
