As a college undergraduate, my advisor gave me the lofty responsibility of walking up and down the scaffold stairs of an eddy-covariance flux tower. My job was to swap out some data cards and dust cobwebs off the sonic anemometer. Today, I am the technician on nine flux towers across the ecologically diverse New Mexico… More

High-elevation montane forests are disproportionately important to carbon sequestration in semiarid climates where low elevations are dry and characterized by low carbon density ecosystems. However, these ecosystems are increasingly threatened by climate change with seasonal implications for photosynthesis and forest growth. As a result, we leveraged eddy covariance data from six evergreen conifer forest sites… More

Water and CO2 flux responses (e.g., evapotranspiration [ET] and net ecosystem exchange [NEE]) to environmental conditions can provide insights into how climate change will affect the terrestrial water and carbon budgets, especially in sensitive semiarid ecosystems. Here, we evaluated sensitivity of daily ET and NEE to current and antecedent (past) environment conditions, including atmospheric (vapor… More
