Short summary
The hardware and software used to collect eddy-covariance ecosystem fluxes of carbon dioxide, heat, and water vapor at a high-elevation subalpine forest site over 17 years are described. Over time, software/hardware improvements have increased the system robustness, leading to a successful 10 Hz data-collection rate of better than 99.98 %. We also provide philosophical concepts that shaped our data system design and are applicable to many different types of environmental data collection.
