Over the past decades, the eddy covariance (EC) community has clearly demonstrated the power of networks; regional networks and FLUXNET have shown us that combining data across multiple sites creates a whole that is greater than the sum of its parts. The FLUXNET database has been used extensively to evaluate satellite measurements, inform Earth system… More

Releases of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from thawing permafrost are expected to be among the largest feedbacks to climate from arctic ecosystems. However, the current net carbon (C) balance of terrestrial arctic ecosystems is unknown. Recent studies suggest that these ecosystems are sources, sinks, or approximately in balance at present….

The AmeriFlux Tech Team has completed another successful site visit season. This year they visited nine AmeriFlux sites. The below gallery features an image from each site visit. The Tech Team is planning for the upcoming site visit season. If you would like to learn more about site visits and what to expect, please see our… More

Aerodynamic canopy height (ha) is the effective height of vegetation canopy for its influence on atmospheric fluxes and is a key parameter of surface‐atmosphere coupling. However, methods to estimate ha from data are limited. This synthesis evaluates the applicability and robustness of the calculation of ha from eddy covariance momentum‐flux data. At 69 forest sites,… More
