Short summary

Turbulent fluxes quantify the exchange of energy, water, or trace gases into and out of the atmosphere. The U.S. Department of Energy Atmospheric Radiation Measurement user facility has been making atmospheric measurements since the early 1990s, including measurements of turbulent fluxes using two well-established methods: the energy balance Bowen ratio and eddy covariance. This paper documents key aspects of these datasets, including their history, changes through time, and best use practices.
