Lianhong Gu’s book review on Terrestrial Biosphere-Atmosphere Fluxes (2014), by Russell Monson and Dennis Baldocchi, is now available at ESA 2015, Book Review, Ecology 96:1736: “Fluxes as functions of ecosystems and drivers of atmosphere.” Read the review at “Monson and Baldocchi, two accomplished researchers and admired educators, masterfully incorporate real equations into a scientific storytelling… More

There is growing interest to use sun induced fluorescence to estimate ecosystem photosynthesis from space.  This new paper from Yang et al tested indices from hyper spectral reflectance measurements with gross carbon fluxes at Harvard forest. Results look interesting and the response between SIF and GPP is much more linear than that between GPP and… More

If you missed the 2015 AmeriFlux Data and Tech Workshop, you can now view videos of several presentations from the workshop online. These presentation may be of use to AmeriFlux tower teams, AmeriFlux data users, and anyone with interest in flux, meteorological, and BADM data. Follow the links below to watch the presentation videos. See… More

Congratulations to Margaret Torn, AmeriFlux Management Project lead PI! Margaret received an honorary doctorate from the University of Zurich last Saturday, in recognition of her efforts to deeper understanding of biogeochemical processes and their climate implications of the soil-plant-atmosphere system, which contribute to science-based solutions to sustainable development of natural resources. She was one of… More

Check out this new feature on the AmeriFlux website. You can now request populated BADM templates for tower sites. To make a request: From the Data menu, choose Download Data. Click the BADM button. Use the form to specify which tower sites and templates you want. Click the Request BADM button. You will receive an… More

By Chad Hanson, AMP Tech Team. Many flux sites do not have access to line power, and run on solar power. This post shares my recent experience of building a simple solar system, and the design considerations that went into it. We hope this will help others as they design and maintain their own systems. Please use the Comments at the… More

During this past AmeriFlux PI Meeting, Gil Bohrer and Tim Morin presented a live demonstration of their Portable Canopy Lidar (PCL), shown in Figure 1, which was developed by their team. The system is based on Lidar (light detection and ranging), which uses pulsed laser light to measure distances based on “time-of-flight.” In the demo,… More

Every spring on the Sevilleta grasslands (elevation 5000 ft), strong northeast winds blow the tumbleweeds down the Rio Grande valley. The tumbleweeds stick to anything that stands out—like the AmeriFlux 3-meter flux tower, US-Seg.  Jonathan Furst, photographer and NMEG research scientist, deals with them every year after the seasonal die-off.  “They stick to each other. They’re covered with… More

Good metadata management is especially important when data are shared across a large community.  Therefore, AmeriFlux is encouraging all sites to fill out an instrument operations (Instrument_Ops) BADM template within the next three months. Both instrument BADM templates have recently been updated: The updated Instrument_Ops template is designed for the submission of basic instrument operations… More

At the 2015 Ameriflux Principal Investigators Meeting in Washington DC, 35 people participated  in a World Cafe session to brainstorm about the Next Big Ideas in climate research. Below are listed the primary themes that emerged from discussions. Tables Three rounds of discussion were held at each table. At the end, participants used dots to indicate favorable… More
