2007- July 2019 overview of fluxes from US-Seg
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 was originally set up as part of the MODIS BIGFOOT project in 2001. My lab has been running the tower since January 2006. It is currently funded by Ameriflux Management Project, which started in 2013. Past sources of funding include: 1) NSF EPSCoR, 2) an award from NSF Ecosystems (2008-2011), 3) a NASA ROSES award (2010-2013), 4) UNM Biology, and 4) Sevilleta LTER. This site burned in August 2009, initiated by a lightning strike.
