2016 - Nov 2022 overview of fluxes from US-Vcs

Figure legend.   Overview of data from the newly established Valles Caldera Sulfur Springs subalpine conifer forest from 2016
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 set up with funding from Ameriflux Management Project using the Rapid Response System. Our original Subalpine mixed conifer site experienced a very hot, stand-replacing burn in late May/early June 2013.
