AmeriFlux is a network of sites and scientists measuring ecosystem carbon, water, and energy fluxes across the Americas using eddy covariance techniques and the many scientists who use these data. The DOE-funded AmeriFlux Management Project (AMP) aims to enhance the value of AmeriFlux for Earth system modeling, terrestrial ecosystem ecology, remote sensing, and many other fields. To do this, AMP has teams focused on four tasks: (1) technical support and quality assessment/quality control (QA/QC), (2) data support and QA/QC, (3) core site support, and (4) outreach. The network continues to grow. In January 2024, AmeriFlux registered its 641st site. The team makes 3,360 site years of flux/met data from 478 sites publicly accessible. These data are used by a large community of scientists and practitioners worldwide. To maintain a high level of support, AMP invests in new data services and is pioneering a new mode of evaluating each site’s data quality (e.g., remote data “visits” and mini workshops). The project also benefits from productive partnerships. For example, the National Ecological Observatory Network’s 47 AmeriFlux sites make it the single largest network-within-the-network. Researchers co-develop data standards and products with the Integrated Carbon Observation System Ecosystem Thematic Centre. The team collaborates with the National Science Foundation–funded FLUXNET-Coop, which co-sponsors workshops, builds early career resources, and strengthens international connections among flux networks. This poster will highlight some of these recent activities, ongoing initiatives for remote sensing and urban fluxes, and special offerings for scientists regardless of previous level of experience, such as the Rapid Response Systems (loaner eddy flux systems for urban environments and other research opportunities) and systems available for DOE Atmospheric Radiation Measurement campaigns (e.g., in the Southeast United States).
